Glossary
Tactile sensing: Measuring touch: where something makes contact and how hard it presses. Robots use tactile data to grip without crushing or dropping what they hold.
Egocentric video: Video recorded from the wearer's own point of view, with a head-worn camera that sees what the person sees while they work with their hands.
Tactile array: A grid of individual touch sensors. Each sensing channel reports pressure at one spot, so 464 channels together map where and how hard the hand is touching.
Force resolution: The smallest change in force a sensor can report. 12-bit means 4,096 steps per reading; 0.1 N is roughly the weight of a 10-gram object.
IMU (inertial measurement unit): A motion sensor. The accelerometer and gyroscope track movement and rotation; a 9-axis IMU adds a magnetometer, a compass for heading.
AprilTag: A printed square marker, like a simple QR code, that a camera can locate precisely. It lets a camera track the hand's position and orientation.
Global-shutter stereo camera: Two cameras side by side, like a pair of eyes. Global shutter captures every pixel at the same instant, so fast hand motion is not skewed.
Field of view: How much of the scene the camera captures, given as the angle across the image's diagonal, width and height.
Stereo baseline: The distance between a stereo camera's two lenses. Comparing the two views gives depth. Calibrated per unit means each camera's exact geometry is measured individually.
Frame-synced inertial data: Motion readings stored inside the video itself, so every frame carries its matching accelerometer and gyroscope data with no separate clock to line up.
