- Microelectrode Array(also: Utah Array, MEA)
- A small grid of fine recording electrodes (typically 96 silicon shanks in a 4mm x 4mm Utah array) surgically implanted into the cerebral cortex to record the electrical activity of individual neurons and small neural populations. Microelectrode arrays are the sensing front-end…
- Microsoft Kinect(also: Kinect, Kinect sensor)
- A motion-sensing device that captures RGB video, depth images, and skeletal tracking data simultaneously. Originally developed for gaming, the Kinect became widely adopted in accessibility research due to its affordable price point (compared to laboratory equipment) and ability…
- Motion capture(also: Mocap)
- The process of recording the movement of objects or people, typically using optical systems with reflective markers, depth cameras, or body-worn sensors. Motion capture is used in accessibility research to create ground-truth datasets for developing assistive body-tracking…
- Mouse(also: Computer Mouse, Optical Mouse)
- A mouse is a hand-operated pointing device that translates relative motion across a flat surface into movement of an on-screen cursor, with one or more buttons and usually a scroll wheel for selection and additional commands. It is the dominant pointing device for desktop…
- Myo Armband(also: Thalmic Myo)
- A commercially available wearable gesture-recognition armband released by Thalmic Labs in 2014 and discontinued in 2018, containing eight dry sEMG electrodes sampling at 200 Hz plus a 9-axis IMU. Despite its discontinuation, the Myo remains widely used in accessibility and HCI…
