Haptic Exploration(also: Tactile Exploration, Touch Exploration)

The process of acquiring spatial and object information through systematic touch and hand movements. Haptic exploration involves active manipulation and movement across surfaces to perceive shape, size, texture, temperature, and spatial relationships. For people who are blind or…

Haptic Field of View(also: Tactile Field of View, Haptic Aperture)

The limited area that can be perceived through touch at any given moment, analogous to the visual field of view but much more restricted. While vision allows perception of an entire scene simultaneously, touch typically provides information only from the area directly under the…

Haptic Perception(also: Tactile Perception, Touch Perception)

The ability to perceive and interpret information through the sense of touch, including the detection of texture, shape, temperature, pressure, and vibration. Haptic perception is a primary information channel for blind and low vision people and is central to the use of…

Head-related transfer function(also: HRTF)

A response function that describes how sound from a specific point in space is filtered by the shape of the outer ear, head, and torso before reaching the eardrum. HRTFs are unique to each individual and are used in spatial audio rendering to create realistic 3D sound over…
