https://interfacemuseum.com/exhibits/ Newest additions and artifacts in the HCI Museum collection. en-us Tue, 07 Jul 2026 15:40:54 GMT https://interfacemuseum.com/exhibits/active-badge/ https://interfacemuseum.com/exhibits/active-badge/ Olivetti Research made an IR badge that told the building where you were. Phones followed you. Desktops moved with you. Privacy was born as a question. Wearable Location-Aware Ubicomp https://interfacemuseum.com/exhibits/cave/ https://interfacemuseum.com/exhibits/cave/ The CAVE turned the room itself into the display: three walls and a floor projecting stereoscopic 3D that surrounded you, rendered from your tracked viewpoint. You walked naturally. Three other people could stand in there with you, making eye contact and pointing at the same virtual objects. VR Immersive Display https://interfacemuseum.com/exhibits/twiddler/ https://interfacemuseum.com/exhibits/twiddler/ A chording keypad you hold like a grenade. MIT wearable researchers typed 60 wpm while walking. Still in production 33 years later. Input Chorded One-Handed https://interfacemuseum.com/exhibits/virtual-fixtures/ https://interfacemuseum.com/exhibits/virtual-fixtures/ In 1992, Louis Rosenberg bolted himself into a full upper-body exoskeleton covered in motors, peered through binocular magnifiers salvaged from a parachute test rig, and reached out to touch a virtual surface that pushed back — the first system to merge real and virtual with force feedback. Augmented Reality Haptic Exoskeleton https://interfacemuseum.com/exhibits/barcode-battler/ https://interfacemuseum.com/exhibits/barcode-battler/ In 1991, Epoch Co. released a handheld LCD game with a built-in barcode scanner. Swipe any product barcode through its slot — cereal, soup, toilet paper — and an algorithm hashed the digits into character stats for turn-based RPG combat. No graphics, just 7-segment numbers. In Japan, it was a mania: products sold out because kids thought they had lucky barcodes. In the West, it flopped completely. A genuinely novel physical-to-digital bridge, decades before Skylanders or QR-code games. Barcode Tangible Gaming https://interfacemuseum.com/exhibits/buchla-lightning/ https://interfacemuseum.com/exhibits/buchla-lightning/ Don Buchla built an optical gesture-sensing MIDI controller 15 years before the Wii. Two wireless wands emit IR light; a photosensor array triangulates their position, velocity, and acceleration in real time. A TMS370 DSP classifies strikes, sweeps, and zones into MIDI notes and controllers. $1,995, hand-built in Berkeley. Used at IRCAM, CCRMA, and Times Square's millennium celebration. Music HCI Gesture Optical Tracking https://interfacemuseum.com/exhibits/ibva/ https://interfacemuseum.com/exhibits/ibva/ A wireless EEG headband that transmitted brainwaves by radio to a Macintosh, converting alpha and beta rhythms into MIDI notes, visuals, and control signals. Shipped April 1991 by Psychic Lab Inc. Used by Mariko Mori at the Venice Biennale, and by HBO to measure TV audience engagement. BCI EEG Wearable Brainwave https://interfacemuseum.com/exhibits/ntt-clearboard/ https://interfacemuseum.com/exhibits/ntt-clearboard/ ClearBoard-1 is one of the most beautiful and strange interaction models ever built. Two people at remote locations each draw on a large glass pane with marker pens. A half-silvered mirror superimposes the remote collaborator's live video face onto the drawing surface, so you see them 'through' the glass while drawing together. CSCW Video Drawing https://interfacemuseum.com/exhibits/digital-desk/ https://interfacemuseum.com/exhibits/digital-desk/ Pierre Wellner pointed a camera and projector at an ordinary desk. Point at printed numbers; the desk calculates and projects the answer onto the paper. Tangible AR Projection https://interfacemuseum.com/exhibits/tongue-touch-keypad/ https://interfacemuseum.com/exhibits/tongue-touch-keypad/ A custom-fitted dental retainer embedding a nine-key keypad, digital encoder, and magnetic-flux radio transmitter — worn on the palate and operated entirely by tongue. Received FDA clearance in 1991, served ~70 quadriplegic users, and established the paradigm for every modern intraoral interface from the Georgia Tech Tongue Drive to MIT's MouthIO. Accessibility Assistive Technology Tongue Interface https://interfacemuseum.com/exhibits/bat-keyboard/ https://interfacemuseum.com/exhibits/bat-keyboard/ The BAT keyboard is one-handed chording reduced to its most elegant form: four finger keys, three thumb keys, a 25-degree tilt, backwards-facing keycaps, and Cherry MX switches with springs so light they had to be custom-modified. Conceived by an Israeli Air Force human-factors specialist who needed to cut fighter-jet control sequences from 32 seconds to 12, then developed with NASA Stennis Space Center for accessibility and spaceflight use. Input Accessibility Wearable https://interfacemuseum.com/exhibits/biomuse/ https://interfacemuseum.com/exhibits/biomuse/ Eight channels of EMG, EOG, and EEG electrodes feed a $20,000 DSP box. Tensing a forearm muscle triggers a synth note. Shifting your gaze bends a parameter. Built at Stanford's CCRMA by Hugh Lusted and Benjamin Knapp in 1990. Performed in concert halls by Atau Tanaka. Used by NASA, the U.S. Air Force, and a disabled child playing video games at Loma Linda Medical Center. Biosignals Music Accessibility Wearable EMG https://interfacemuseum.com/exhibits/datahand-keyboard/ https://interfacemuseum.com/exhibits/datahand-keyboard/ The most extreme keyboard redesign ever brought to market. Each finger rests in a padded well with five magnetic switches (N/S/E/W + center). No wrist movement, sub-millimeter finger twitches. Invented by Dale Retter to solve his own RSI, prototyped by 1989, sold from 1990. HCI Input Ergonomic https://interfacemuseum.com/exhibits/grope-iii/ https://interfacemuseum.com/exhibits/grope-iii/ Repurposed a nuclear-industry teleoperator arm from Argonne National Lab as a 6-DOF haptic force display. Chemists grasped a handle and felt real-time electrostatic forces — steric repulsion, van der Waals attraction, and Coulomb forces — guiding drug molecules into protein receptor sites. Demonstrated a two-fold performance improvement over purely visual interaction and founded the field of haptic rendering. Haptics Force Feedback Scientific Visualization https://interfacemuseum.com/exhibits/konami-laserscope/ https://interfacemuseum.com/exhibits/konami-laserscope/ An astonishingly ambitious consumer wearable from 1990: head-mounted crosshair eyepiece + voice trigger + light gun sensor, all for $39.95. It combined head-based spatial aiming, voice input, heads-up display, and stereo headphones into a single NES peripheral. That it failed spectacularly — the mic triggered on any loud noise, neck fatigue from head-aiming, and you still needed a regular Zapper to make it work — makes it a perfect HCI design-failure case study. Voice Control Head-Mounted Display Gaming https://interfacemuseum.com/exhibits/minsky-sandpaper/ https://interfacemuseum.com/exhibits/minsky-sandpaper/ The origin story of computational haptics — the moment touch became programmable. Margaret Minsky's 2-DOF force-feedback joystick used a lateral-force algorithm to synthesize virtual textures (sandpaper, rubber, velvet) that users could genuinely feel and distinguish. A wooden box with DC motors, optical encoders, and metal linkages — every haptic device since descends from it. Haptics Force Feedback MIT Media Lab https://interfacemuseum.com/exhibits/williams-facial-animation/ https://interfacemuseum.com/exhibits/williams-facial-animation/ At SIGGRAPH 1990, Lance Williams of Apple ATG introduced the 'electronic mask': retroreflective dots on an actor's face tracked by computer vision, driving a photorealistic 3D CG character in real time. The actor's smile, frown, or raised eyebrow became a real-time animation input stream — the birth of facial performance capture, decades before Avatar or ARKit. Williams later served as Chief Scientist at Walt Disney Animation Studios and won a Technical Academy Award for this work. Facial Tracking Computer Vision Performance Capture https://interfacemuseum.com/exhibits/sega-r360/ https://interfacemuseum.com/exhibits/sega-r360/ A 1,100 kg gyroscopic arcade sphere that rotated freely through 360 degrees on two axes, physically inverting the player to match in-game flight. $90,000 per unit. Emergency stops on every installation. Only ~100 were ever built. Motion Platform Arcade Kinesthetic Simulation https://interfacemuseum.com/exhibits/virtuality/ https://interfacemuseum.com/exhibits/virtuality/ Amiga 3000s, camcorder LCDs, and magnetic tracking. Dactyl Nightmare let four players fight in cyberspace years before Doom. VR Arcade Multiplayer https://interfacemuseum.com/exhibits/xerox-liveboard/ https://interfacemuseum.com/exhibits/xerox-liveboard/ The LiveBoard was the moment collaborative computing outgrew the desk. A 67-inch rear-projection display with laser-based pen sensing, built from repurposed Xerox copier parts, let multiple people write simultaneously on a shared digital wall. The Colab room that housed it — with motorized desks, no-glare lighting, and four networked workstations — was an entire physical environment designed around a new way of working together. Input Display CSCW https://interfacemuseum.com/exhibits/dragondictate/ https://interfacemuseum.com/exhibits/dragondictate/ Dragon Systems' husband-wife team put 30,000-word speech recognition on a 386 PC with a $9,000 ISA DSP board and Shure headset. Defined the dictation interaction model: speak, pause, 'Oops' to correct. Life-changing for quadriplegic users. Speech Recognition Dictation Natural Language https://interfacemuseum.com/exhibits/fakespeare-boom/ https://interfacemuseum.com/exhibits/fakespeare-boom/ Suspended two 1280x1024 CRTs and LEEP optics inside a viewing hood on a spring-balanced articulated arm. Gripped the handles, pressed your face in, and physically wrestled the display through space — joint encoders giving sub-millisecond 6-DOF tracking. Invented by Mark Bolas (who later mentored Oculus founder Palmer Luckey). Used by NASA, Boeing, and Sandia Labs. VR Immersive Display Head-Coupled Display https://interfacemuseum.com/exhibits/gridpad-100/ https://interfacemuseum.com/exhibits/gridpad-100/ Pioneered portable form-factor handwriting recognition and stylus-driven UI on MS-DOS. pen computing handwriting recognition tablet PC https://interfacemuseum.com/exhibits/hard-drivin/ https://interfacemuseum.com/exhibits/hard-drivin/ First commercial arcade game with continuous force-feedback steering (not vibration — actual road-force resistance). Full manual transmission with clutch and H-pattern shifter. Real vehicle dynamics by Doug Milliken, credited as 'test driver' to keep it secret. 3,318 cabinets built. Every modern force-feedback racing wheel descends from this. Force Feedback Haptics Arcade Simulation https://interfacemuseum.com/exhibits/nintendo-hands-free/ https://interfacemuseum.com/exhibits/nintendo-hands-free/ Designed for quadriplegic players and co-developed with Seattle Children's Hospital. A chest-strapped device with a chin-operated joystick for directional movement and a sip-and-puff tube: sipping activates A, puffing activates B. Sold at cost via mail-order with zero marketing, predating Microsoft's Xbox Adaptive Controller by 29 years. Very few units survive today. Accessibility Sip-and-Puff Assistive Technology https://interfacemuseum.com/exhibits/poqet-pc/ https://interfacemuseum.com/exhibits/poqet-pc/ Pushed the limits of portable full-PC interaction years before Palm and Windows CE. Palmtop PC Power Management MS-DOS https://interfacemuseum.com/exhibits/nintendo-power-glove/ https://interfacemuseum.com/exhibits/nintendo-power-glove/ Mattel had nine months to turn VPL's research-grade DataGlove into a toy. It sold 1.3 million units. "I love the Power Glove. It's so bad." Gesture Gaming Wearable https://interfacemuseum.com/exhibits/private-eye/ https://interfacemuseum.com/exhibits/private-eye/ A 2.5-ounce monochrome display using 280 LEDs and a vibrating mirror to paint a 720x280 image onto your retina. By covering only one eye, your brain fused the display with reality — accidental AR, years before the term existed. MIT researchers wore them daily. Google Glass traces its lineage here. Head-Mounted Display Wearable Augmented Reality https://interfacemuseum.com/exhibits/uforce/ https://interfacemuseum.com/exhibits/uforce/ Broderbund Software had never made hardware. Then it shipped a clamshell pad with nine IR emitter-detector pairs that tracked your hand in 3D space above the NES. Ambient light confused it. Calibration drifted. 'Don't Touch!' became an ironic epitaph. A perfect HCI failure study. Touchless Input Infrared Sensing Gaming https://interfacemuseum.com/exhibits/vpl-datasuit/ https://interfacemuseum.com/exhibits/vpl-datasuit/ The VPL DataSuit extended the DataGlove's fiber-optic bend sensor technology from one hand to the entire body. Worn as a tight Lycra outfit with 30+ sensors measuring joint angles along arms, legs, and trunk, it made the human body a real-time input device for virtual environments. Combined with the EyePhone HMD and DataGlove in VPL's 'Reality Built for Two' (RB2) — the first multi-user VR system — it embodied Jaron Lanier's concept of 'post-symbolic communication': using body movement as a programming language. Ann Lasko-Harvill designed gender-specific tailoring for different body types. The suit appeared in the 1992 film The Lawnmower Man, introducing full-body VR to mass audiences. Though VPL filed for bankruptcy in 1990, the DataSuit established the template for every full-body tracking system that followed. VR Wearable Motion Capture Full-Body https://interfacemuseum.com/exhibits/convolvotron/ https://interfacemuseum.com/exhibits/convolvotron/ Built under a NASA contract by Scott Foster and Crystal River Engineering, the Convolvotron was the first system capable of real-time binaural spatialization of multiple independent sound sources. A custom parallel ALU engine with 128 16×16 multiply-accumulators performed head-related transfer function (HRTF) convolution in real time — as you turned your head, virtual sound sources stayed anchored in 3D space through standard stereo headphones. At $14,995 for a two-board PC set, it spawned a product family (Acoustetron, Beachtron, Alphatron) and was used in landmark VR artworks including Brenda Laurel's Placeholder and Char Davies' Osmose. Its technology was distilled into Aureal's A3D consumer 3D audio API before being acquired by Creative Technology. Audio Spatial Audio VR NASA https://interfacemuseum.com/exhibits/nes-power-pad/ https://interfacemuseum.com/exhibits/nes-power-pad/ A foldable plastic floor mat with 12 pressure sensors that turned the player's entire body into a game controller. Years before DDR, Wii Fit, or Kinect, the Power Pad proved that feet and whole-body movement could be a viable consumer input modality. It pioneered exergaming, invented the 'body as controller' paradigm, and is the direct ancestor of every motion-based game interface that followed. Plus, kids discovered you could cheat by kneeling and slapping the mat with your hands. Full-Body Input Exergaming Floor Mat https://interfacemuseum.com/exhibits/p300-speller/ https://interfacemuseum.com/exhibits/p300-speller/ The first BCI that let you type with brainwaves alone. Focus on a letter in a 6×6 grid; the system reads the P300 spike when your target flashes. 95% accuracy at 12 bits/min. Brain Control BCI EEG https://interfacemuseum.com/exhibits/kramers-talking-glove/ https://interfacemuseum.com/exhibits/kramers-talking-glove/ The first portable ASL-to-speech translation system: 14 strain-gauge flex sensors, a beacon recognition algorithm in 16-dimensional hand-space, and a DECtalk speech synthesizer. Built by James Kramer at Stanford (1988–1991) for deaf users to have everyday conversations without an interpreter. The sensor design proved so robust it became the CyberGlove, dominating VR hand-input for two decades before Immersion Corp acquired it and leveraged the patents against Microsoft and Sony. Wearable Accessibility Gesture Recognition https://interfacemuseum.com/exhibits/akai-ewi-1000/ https://interfacemuseum.com/exhibits/akai-ewi-1000/ A wind instrument controller from 1987 where every key is a capacitive touch sensor. Zero mechanical travel, zero clicks. Breath pressure, bite pressure, and finger capacitance combined into three continuous MIDI channels. Nyle Steiner invented it in his Utah basement. Akai sold it to jazz musicians who needed more than a keyboard could give. Music Capacitive Touch Breath Control MIDI https://interfacemuseum.com/exhibits/canon-cat/ https://interfacemuseum.com/exhibits/canon-cat/ No files, no applications, no operating system — just a single unified document stream navigated by content via pink LEAP keys. Designed by the man who initiated the Macintosh, it represents the road not taken in personal computing. The interaction model IS the point. HCI Input Interface Paradigm https://interfacemuseum.com/exhibits/exciting-boxing/ https://interfacemuseum.com/exhibits/exciting-boxing/ An inflatable, life-sized boxer with 11 internal pressure sensors that plugged into the Nintendo Famicom. You stood on a mat, put on knitted gloves, and physically punched the bag. Konami, 1987. Full-body motion gaming nearly two decades before the Wii. Game Controller Full-Body Input Motion Gaming Famicom https://interfacemuseum.com/exhibits/scanman/ https://interfacemuseum.com/exhibits/scanman/ Logitech's 1987 handheld scanner. Four inches wide, 200 dpi, serial port. No motor: the user physically dragged it across the page at a steady speed, with a roller encoder syncing capture and an LED warning if you moved too fast. Scan quality was a direct function of your hand steadiness. Input Scanner Handheld Embodied https://interfacemuseum.com/exhibits/polhemus-isotrak/ https://interfacemuseum.com/exhibits/polhemus-isotrak/ First widely available electromagnetic tracker enabling freehand spatial input in VR and CAD. 6DOF Tracking Electromagnetic Tracking Virtual Reality https://interfacemuseum.com/exhibits/radio-drum/ https://interfacemuseum.com/exhibits/radio-drum/ Max Mathews, father of computer music, and Bell Labs engineer Bob Boie built a 3D mouse that failed. Then they realized it was a musical instrument. Two batons hover above a capacitance-sensing antenna plate, tracking X, Y, and Z at 100Hz with 1mm precision. No contact required. 3D Spatial Input Music HCI Gestural Controller https://interfacemuseum.com/exhibits/headmaster/ https://interfacemuseum.com/exhibits/headmaster/ The first commercially successful head-operated computer cursor controller. A lightweight headset with three 40 kHz ultrasonic receivers tracked rotational head movement (yaw and pitch) through analog phase-comparison circuitry, sampled at 1,000 Hz with sub-millimeter resolution. A sip-and-puff mouth switch provided mouse-button clicks. Built by Personics Corp in 1986 for $795, later sold by Prentke Romich Company through the 2000s, it came with ScreenTyper — an on-screen keyboard with characters arranged by frequency of use, a decade before soft keyboards became common. Its patent was classified under G06F3/012 'Head tracking input arrangements' — the same classification that would define VR input. Units are held by both the Smithsonian and the Computer History Museum. Head Tracking Accessibility Ultrasonic Cursor Control https://interfacemuseum.com/exhibits/mandala/ https://interfacemuseum.com/exhibits/mandala/ The Vivid Group put your live video silhouette inside a virtual world. Punch objects, play drums, dance — 30fps, no controller, on an Amiga 1000. Gesture VR Computer Vision https://interfacemuseum.com/exhibits/psion-organiser-ii/ https://interfacemuseum.com/exhibits/psion-organiser-ii/ Early PDA that demonstrated mobile database and calculator interaction models. Personal Digital Assistant Mobile Database Calculator https://interfacemuseum.com/exhibits/sgi-dial-box/ https://interfacemuseum.com/exhibits/sgi-dial-box/ A dedicated 3D input peripheral for Silicon Graphics IRIS workstations: eight continuous-rotation optical encoder dials and thirty-two programmable buttons in a metal chassis. Animators used their left hand on the dials (rotate, zoom, pan) while the right hand worked the mouse — an asymmetric bimanual workflow later studied by Bill Buxton at the University of Toronto. The dial box represents a lost design philosophy: that professional creative tools deserve dedicated, task-specific physical controls. Every modern 3D app's orbit/zoom/pan navigation inherits the SGI dial layout, but the physical knobs are gone. 3D Interaction Professional Workstation Bimanual https://interfacemuseum.com/exhibits/cauzin-softstrip/ https://interfacemuseum.com/exhibits/cauzin-softstrip/ The Cauzin Softstrip is the most literal 'paper-to-silicon bridge' ever sold as a consumer computer peripheral. You physically dragged this beige wand over a strip of tiny black-and-white squares printed in Byte magazine, and 5,500 bytes of program code materialized on your Apple II. Co-founder Jack Goldman had founded Xerox PARC. It won MacUser's 'Most Innovative Concept of 1986' and died within three years, outrun by floppy disks and modems. Input Scanning Optical Reader https://interfacemuseum.com/exhibits/cmu-sensor-frame/ https://interfacemuseum.com/exhibits/cmu-sensor-frame/ Before the iPhone, before Jeff Han's TED talk, there was a metal frame around a CRT monitor at Carnegie Mellon that tracked three fingers, detected their approach angle, and recognized gestures — including canonical pinch-to-zoom in 1985. The sensors were off-the-shelf DRAM memory chips repurposed as crude cameras because CCDs were unavailable. Steve Jobs visited the lab in October 1985 and signed an NDA. The technology was patented, a company was founded, NASA funded a 3D variant — and then nothing. It never shipped. But the idea it proved is now in every pocket. Multi-Touch Gesture Input Research https://interfacemuseum.com/exhibits/etak-navigator/ https://interfacemuseum.com/exhibits/etak-navigator/ A shoebox-sized 8088 computer in the trunk, a compass on the rear windshield, wheel sensors on the brakes, and maps on high-speed cassette tapes. No GPS — just dead reckoning and a map-matching algorithm that snapped your position to the nearest road. Nolan Bushnell seed-funded it after a 4am yacht conversation. Its heading-up rotating map display and triangular arrow symbol became the universal standard for every navigation app since. Navigation Automotive Map Display Location https://interfacemuseum.com/exhibits/eyetap/ https://interfacemuseum.com/exhibits/eyetap/ Steve Mann built camera-display eyeglasses in high school. The computer mediates reality itself — not a HUD, but a reversible eye. Wearable AR Sousveillance https://interfacemuseum.com/exhibits/nintendo-d-pad-controller/ https://interfacemuseum.com/exhibits/nintendo-d-pad-controller/ Established the dominant discrete directional input paradigm still used in handheld and console gaming. D-pad Game controller NES https://interfacemuseum.com/exhibits/nintendo-rob/ https://interfacemuseum.com/exhibits/nintendo-rob/ R.O.B. is an output device disguised as a friend. The NES draws flashing green and black rectangles on a CRT screen. A phototransistor in R.O.B.'s head decodes the pulses into motor commands. Three DC motors grind into action, and the robot reaches into the real world to press buttons on a second controller. Designed by Gunpei Yokoi. Discontinued by 1988. But before that, it saved Nintendo — retailers wouldn't stock a 'video game console' after the 1983 crash, so they bundled a robot and called it a toy. Robotics Game Peripheral Physical Computing Embodied Interaction https://interfacemuseum.com/exhibits/puma-rs-computer-shoes/ https://interfacemuseum.com/exhibits/puma-rs-computer-shoes/ The PUMA RS-Computer transformed a shoe into an active sensing peripheral, measuring stride timing to compute distance, speed, and calories. After a run, you physically plugged your shoes into a computer's printer port to download data — a ritual that anticipated every fitness wearable by 20 years. HCI Wearable Sensing https://interfacemuseum.com/exhibits/rdi-halcyon/ https://interfacemuseum.com/exhibits/rdi-halcyon/ A consumer device in 1985 that bet its entire identity on speech recognition. No joystick, no keyboard — you talked to it through a noise-canceling headset while it navigated branching laserdisc movies with your spoken commands. Funded by Dragon's Lair profits, killed by the 1983 game crash and a price tag that bought 14 NES consoles. One of the rarest game consoles ever made. Gaming Voice Recognition Laserdisc https://interfacemuseum.com/exhibits/sega-hang-on/ https://interfacemuseum.com/exhibits/sega-hang-on/ Before Hang-On, every arcade game was played with fingers. Then Yu Suzuki built a full-size motorcycle cabinet with a spring-loaded axle that translated body lean into steering. Players straddled it, twisted a real throttle, squeezed real brake levers, and leaned through corners. It sold 20,000 units, was the highest-grossing arcade game of 1985 in the US and 1986 in both Japan and the US, and launched Sega's decade of taikan ('body sensation') motion simulators. Suzuki, a motorcyclist himself, built it for '16-year-old males' who wanted to ride but couldn't get a license. Arcade Motion Full-Body Gaming https://interfacemuseum.com/exhibits/synthaxe/ https://interfacemuseum.com/exhibits/synthaxe/ A fretted MIDI guitar controller with two independent sets of strings at an angle: one for pitch (electrical fret scanning, zero latency) and one for triggering (Hall-effect velocity sensing). Funded by Virgin Group, priced like a small car, built from aerospace materials. Allan Holdsworth called it 'the only guitar synthesizer that really works.' Virgin pulled out, the company folded, and the remaining instruments became holy grails. Music MIDI Gesture https://interfacemuseum.com/exhibits/drawing-prism/ https://interfacemuseum.com/exhibits/drawing-prism/ A transparent glass prism that let artists paint with real brushes, fingers, or any light-colored object directly into a computer's frame buffer in 1985. A video camera underneath saw only points of optical contact via frustrated total internal reflection. HCI Input Art https://interfacemuseum.com/exhibits/versatron-footmouse/ https://interfacemuseum.com/exhibits/versatron-footmouse/ The Versatron Footmouse (1985) was the first commercially available foot-operated cursor controller. A keyboard-wedge device that plugged between the keyboard and PC, it injected cursor-key scan codes when you slid your foot across its surface — no mouse drivers needed. The company that built it, Versatron Corporation, was primarily a defense contractor making actuators for Stinger missiles and the Excalibur artillery shell. The footmouse was their one consumer product: a sliding-pedal floor unit designed for accessibility, years before the ADA. Foot Input Accessibility Cursor Control https://interfacemuseum.com/exhibits/vpl-research/ https://interfacemuseum.com/exhibits/vpl-research/ Jaron Lanier's fiber-optic glove and Fresnel-lens headset defined the visual language of virtual reality. A full system cost $250,000 and ran at 5 fps. VR Gesture Wearables https://interfacemuseum.com/exhibits/aesthedes/ https://interfacemuseum.com/exhibits/aesthedes/ A dedicated graphic-design workstation where every function had a physical key spread across the desk surface — 583 membrane switches on the Aesthedes 1, 636 on the Aesthedes 2. Six screens (three colour, three monochrome) gave every view its own monitor. Ten Motorola 68000 CPUs, 220 kg, and a price tag of $150,000. It designed Dutch banknotes, Heineken labels, and Volvo dashboards before the Macintosh killed it. CAD Workstation Keyboard https://interfacemuseum.com/exhibits/armatron/ https://interfacemuseum.com/exhibits/armatron/ Tomy/Radio Shack's six-degree-of-freedom tabletop robotic arm, operated through purely mechanical dual joysticks with zero digital electronics. The user's hand movements engage rotating gear drums that map directly onto wrist rotation, elbow bend, shoulder elevation, and gripper — a waldo for the price of a board game. Robot Teleoperation Mechanical Toy https://interfacemuseum.com/exhibits/atari-mindlink/ https://interfacemuseum.com/exhibits/atari-mindlink/ A headband that read forehead muscle tension and called it telepathy. Demoed at CES, then canceled. Testers got headaches from wiggling their brows. BCI Biofeedback Vaporware https://interfacemuseum.com/exhibits/koalapad/ https://interfacemuseum.com/exhibits/koalapad/ Brought absolute-position drawing and menu selection to consumer software years before mainstream mice. Graphics Tablet Touch Tablet Absolute Positioning https://interfacemuseum.com/exhibits/seiko-rc1000/ https://interfacemuseum.com/exhibits/seiko-rc1000/ The same year the Macintosh shipped, Seiko sold a wristwatch with 2KB RAM, a 12x2 dot-matrix LCD, and an RS-232C serial port. You authored data on a desktop PC, then blasted it to the watch in a 2051-byte dump. Read-only on the wrist. Spawned the WristMac, which flew on Space Shuttle Atlantis in 1991 for the first email from space. Wearable Wrist-Worn Mobile Computing https://interfacemuseum.com/exhibits/soundbeam/ https://interfacemuseum.com/exhibits/soundbeam/ Touch-free MIDI controller using 50 kHz sonar beams. Conceived by composer Edward Williams, built by the EMS team (legendary VCS3 synth). Dancers were supposed to use it. Instead, children with profound disabilities made music for the first time. Still in production in 2025. Sonar Music MIDI Gestural Accessibility Embodied https://interfacemuseum.com/exhibits/relax-stress-reduction/ https://interfacemuseum.com/exhibits/relax-stress-reduction/ An EMG headband, control unit, and software that let you fly a balloon by relaxing. Synapse Software (of Blue Max fame) got FDA clearance as a Class II medical device in 1984. Co-created by legendary game designer Bill Williams. Rarity 9 on AtariMania. Biofeedback Physiological Computing Wearable https://interfacemuseum.com/exhibits/amiga-joyboard/ https://interfacemuseum.com/exhibits/amiga-joyboard/ Arguably the first commercial full-body input device for a home video game console, predating the Wii Balance Board by 23 years. A plastic board you stood on and leaned to control on-screen action, translating gross motor movement into digital directional input through simple mechanical latches. Balance Board Full-Body Interaction Game Controller https://interfacemuseum.com/exhibits/atarilab/ https://interfacemuseum.com/exhibits/atarilab/ In 1983, physics professor Priscilla Laws realized the Atari's joystick port was secretly a general-purpose ADC. She built a breakout box that turned the Atari 800 into a real-time lab instrument: plug in a temperature probe, dip it in water, and watch a cooling curve draw itself on the family TV. The software was written by a 15-year-old. Atari collapsed before a dozen planned modules could ship, but Laws's concept lived on — the Universal Laboratory Interface she later co-developed sold 40,000 units through Vernier Software and launched the modern probeware industry. Education Sensors Physical Computing https://interfacemuseum.com/exhibits/butler-in-a-box/ https://interfacemuseum.com/exhibits/butler-in-a-box/ The Butler in a Box (1983) pioneered the wake-word-plus-command interaction model that now powers every smart speaker. You trained it to recognize a butler name ('Godfrey,' 'Hobson'), it responded 'Yes, boss,' and then controlled your lights, phone, timers, and alarm — all by voice. Created by professional magician Gus Searcy and former IBM programmer Franz Kavan. Priced at $1,495. It could handle 256 functions, 4 users' voice profiles, and if-then conditional logic. A Smithsonian artifact. Voice Control Home Automation Speech Recognition https://interfacemuseum.com/exhibits/eyetyper/ https://interfacemuseum.com/exhibits/eyetyper/ A video camera pointed at one eyeball. A display board with oversized characters. Hold your gaze — and type at 10 words per minute. CMU spinoff Sentient Systems launched EyeTyper in 1983; the company became DynaVox, then Tobii Dynavox. Eye-Tracking Accessibility Camera-Based Input https://interfacemuseum.com/exhibits/hp-150-touchscreen/ https://interfacemuseum.com/exhibits/hp-150-touchscreen/ First mass-market computer to ship with direct finger touch as primary input. Touchscreen Infrared touch MS-DOS computer https://interfacemuseum.com/exhibits/hubot/ https://interfacemuseum.com/exhibits/hubot/ A 50kg wheeled companion with a CP/M computer, a voice synthesizer, an Atari 2600, and a Polaroid sonar head. Priced at $3,495, it scanned rooms, spoke 1,200 words, and played Defender. Robot Voice Home Computer https://interfacemuseum.com/exhibits/mbx-expansion-system/ https://interfacemuseum.com/exhibits/mbx-expansion-system/ In 1983, Milton Bradley shipped a peripheral that wore a headset, learned your voice, understood spoken game commands, and paired them with a 360-degree analog joystick with a twist knob and a 64-key membrane overlay keypad. Voice-recognition gaming in 1983. HCI Input Voice https://interfacemuseum.com/exhibits/vectrex-3d-imager/ https://interfacemuseum.com/exhibits/vectrex-3d-imager/ The first commercially released stereoscopic 3D gaming peripheral: a headset with a spinning half-black, half-RGB filter disk synced to the Vectrex vector CRT via PWM motor control. Only ~2,000 units escaped before the 1983 crash. Invented by John Ross, who also created the Vectrex itself. 3D Display Gaming Electromechanical Stereoscopic https://interfacemuseum.com/exhibits/heathkit-hero-1/ https://interfacemuseum.com/exhibits/heathkit-hero-1/ Brought programmable physical-world sensing and locomotion to hobbyist HCI experiments. Educational Robot Programmable Sensing Human-Computer Interaction https://interfacemuseum.com/exhibits/pencept-penpad/ https://interfacemuseum.com/exhibits/pencept-penpad/ A terminal replacement with no keyboard—just a pen and tablet. Used MIT-developed user-independent handwriting recognition and gesture commands (circle to select, scribble to delete). CHI '85 demo showed real-time pen computing a decade before the Newton. Pen Computing Handwriting Recognition Gesture https://interfacemuseum.com/exhibits/dlr-spacemouse/ https://interfacemuseum.com/exhibits/dlr-spacemouse/ A tennis-ball-sized sphere that reads minute hand pressures — not position, not movement, but force — and translates them into simultaneous control of all six degrees of freedom. Developed at the German Aerospace Center in 1981. Used on Space Shuttle Columbia. Still in production as the 3Dconnexion SpaceMouse. 6-DOF Input Force Input Spatial Controller https://interfacemuseum.com/exhibits/gibson-light-pen/ https://interfacemuseum.com/exhibits/gibson-light-pen/ Steve Gibson's LPS II (1981) was the finest light pen ever made for an 8-bit microcomputer. A photodetector in the pen tip tracked the CRT's electron beam for 1:1 absolute positioning — drawing directly on screen felt, as one reviewer put it, 'utterly analogous to working with a normal pen.' At $250 it bridged the gap between toy tablets and $1,000+ CAD digitizers. Gibson sold the company to Atari, recovered the rights, licensed to Koala, then founded Gibson Research Corporation — making SpinRite and co-hosting Security Now! for decades. Light Pen Apple II Drawing Input https://interfacemuseum.com/exhibits/quantel-paintbox/ https://interfacemuseum.com/exhibits/quantel-paintbox/ The first computer graphics system designed as an artist's tool rather than an engineer's. Its patented pressure-sensitive stylus and tablet, combined with real-time pop-up menus, let traditionally trained illustrators produce broadcast-quality digital graphics with zero computer knowledge. A decade before consumer tablets and Photoshop, it proved natural gestural interaction could power professional creative work. Graphics HCI Pressure-Sensitive Stylus Broadcast Graphics https://interfacemuseum.com/exhibits/microwriter/ https://interfacemuseum.com/exhibits/microwriter/ Early wearable-style one-handed text entry device aimed at mobile professionals. chording keyboard portable computing mobile text entry https://interfacemuseum.com/exhibits/put-that-there/ https://interfacemuseum.com/exhibits/put-that-there/ MIT's Architecture Machine Group let you move shapes by speaking and pointing. It asked clarifying questions when it couldn't understand you. Voice Gesture Multimodal https://interfacemuseum.com/exhibits/big-trak/ https://interfacemuseum.com/exhibits/big-trak/ Milton Bradley's six-wheeled programmable tank (1979). A TI TMS1000 microcontroller, 16 command memory, and no screen — you typed FORWARD 5, RIGHT 15, FIRE on the keypad and the tank carried out your orders on the living room floor. Carnegie Mellon psychologists adopted it to study how humans learn without instructions. Robot Programming Education Toy https://interfacemuseum.com/exhibits/fairlight-cmi/ https://interfacemuseum.com/exhibits/fairlight-cmi/ The first commercially successful creative tool that used a light pen for direct-manipulation content creation. Musicians drew sound waveforms on a CRT and composed visually via Page R, the first graphical pattern sequencer. Years before the Macintosh, it proved that visual, gestural interfaces could power professional creative work. Music HCI Light Pen Digital Audio https://interfacemuseum.com/exhibits/talking-signs/ https://interfacemuseum.com/exhibits/talking-signs/ A network of infrared transmitters that broadcast spoken labels on modulated light beams. A blind person carrying a pocket receiver could 'read' the city by pointing it around — doorways, bus stops, ATMs would whisper their names with directional clarity. Codified into US federal building standards (ADAAG 703.7) in 2000. In 2016, the concept became a free smartphone app used by thousands daily. Accessibility Infrared Navigation https://interfacemuseum.com/exhibits/versabraille/ https://interfacemuseum.com/exhibits/versabraille/ A 20-cell piezoelectric Braille display that functioned as notetaker, reading machine, and computer terminal — giving blind users direct tactile access to electronic text for the first time. The same transducer technology invented for this device still powers most Braille displays today. HCI Accessibility Tactile https://interfacemuseum.com/exhibits/reading-epg/ https://interfacemuseum.com/exhibits/reading-epg/ One of the most intimate human-computer interfaces ever built. A custom-molded acrylic plate, clipped to the user's upper teeth like a retainer, carries 62 gold electrodes in an 8-row grid. When the tongue touches the palate during speech, a CRT monitor illuminates dots wherever contact occurs—turning the invisible act of articulation into a visible, teachable skill. Developed at the University of Reading in 1978. Biofeedback Speech Therapy Accessibility https://interfacemuseum.com/exhibits/speak-spell/ https://interfacemuseum.com/exhibits/speak-spell/ Texas Instruments put a 10th-order LPC vocal tract model on a single chip. It taught kids to spell, became an IEEE Milestone, and soundtracked Kraftwerk. Voice Speech Synthesis Toy https://interfacemuseum.com/exhibits/videoplace/ https://interfacemuseum.com/exhibits/videoplace/ Myron Krueger put people in shared silhouette worlds using only cameras and projectors. No headsets, no gloves — just your body, glowing on screen. Gesture Computer Vision Art https://interfacemuseum.com/exhibits/writehander/ https://interfacemuseum.com/exhibits/writehander/ Early commercial attempt at compact, eyes-free chorded text entry that predates later wearable keyboards. Chorded Keyboard Wearable Eyes-Free https://interfacemuseum.com/exhibits/summagraphics-bit-pad/ https://interfacemuseum.com/exhibits/summagraphics-bit-pad/ Standardized absolute coordinate input for professional graphics long before consumer tablets. Digitizing Tablet Absolute Positioning Professional Graphics https://interfacemuseum.com/exhibits/upic/ https://interfacemuseum.com/exhibits/upic/ A music composition tool with no keyboard, no notation, no code — just drawing. Xenakis, the avant-garde composer who had worked for Le Corbusier, built a large electromagnetic drawing tablet where the X-axis was time and the Y-axis was pitch. Draw a waveform shape → that's the timbre. Draw an envelope → that's the dynamics. Draw a line across the grid → that's the melody. Designed to be usable by children. The entire system fit in under a megabyte. Aphex Twin called it 'under 1mb and it shits on everyone.' His first UPIC piece premiered at the Acropolis of Mycenae. Music Drawing Tablet Synthesis https://interfacemuseum.com/exhibits/kurzweil-reading-machine/ https://interfacemuseum.com/exhibits/kurzweil-reading-machine/ The first omni-font OCR plus a CCD scanner plus a speech synthesizer. Walter Cronkite read his sign-off with it. Stevie Wonder took the first unit home. Accessibility OCR Text-to-Speech
