- Haptic Design(also: Vibrotactile Design, Haptic Authoring)
- The practice of authoring haptic feedback - typically vibrations, forces, or temperature cues - so that it conveys intended meaning, emotion, or synchronicity with other media. Haptic design involves choosing signal parameters such as amplitude, frequency, timing, and spatial…
- 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 Graph(also: Haptic Chart, Force-feedback Graph)
- A haptic graph is a non-visual rendering of a chart or graph — a bar chart, line graph, scatter plot, or mathematical function — that a blind or low-vision user explores by touch, typically through a force-feedback haptic device such as the PHANToM or a vibrotactile tablet.…
- Haptic Icon(also: Hapticon)
- A short, structured vibrotactile or force pattern designed to carry meaning in the same way a graphical icon or audio earcon does, allowing users to recognize a category of information — an alert, material, identity, or state — through touch alone. The concept generalizes…
- Haptic Rendering(also: Haptic display rendering)
- The process of computing and outputting touch-based signals — forces, vibrations, textures, or friction — so that a user can perceive virtual or remote objects through the sense of touch. Haptic rendering covers kinesthetic rendering (force feedback via joysticks, exoskeletons,…
