- DataGlove(also: Data Glove, Sensor Glove, Cyber Glove)
- A wearable input device fitted with sensors that captures hand shape, finger position, and hand orientation data in real time. Originally developed by VPL Research in the 1980s, DataGloves were used extensively in early virtual reality and sign language recognition research to…
- Eye tracking(also: Gaze tracking, Eye-gaze tracking, Eye Tracker)
- A technology that measures where a person is looking on a screen or in an environment by detecting eye position and movement, typically using infrared light and cameras. In accessibility, eye tracking serves dual roles: as an assistive input method allowing people with severe…
- Force-sensitive resistor(also: FSR, Pressure sensor)
- An electronic sensor whose electrical resistance changes in response to applied physical pressure, enabling detection of both the presence and intensity of touch or force. In accessibility applications, force-sensitive resistors offer advantages over capacitive touchscreens…
- Leap Motion(also: Leap Motion Controller)
- A compact infrared hand-tracking sensor that uses binocular cameras to detect and track finger and hand positions in three-dimensional space without physical contact. In accessibility research, Leap Motion controllers have been used to create touchless interfaces for people with…
- PHANTOM(also: PHANTOM Omni, PHANTOM Desktop, SensAble PHANTOM)
- A family of force-feedback haptic devices originally developed by SensAble Technologies (now part of 3D Systems). PHANTOM devices use a pen-like stylus that users grasp while motors apply forces to create the sensation of touching virtual objects or being guided along…
