Haptic Design

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 distribution, often through specialised tools that provide libraries of effects, timeline editors, or reference-based authoring from audio or video. For accessibility, well-designed haptic feedback can substitute for visual or auditory information, enable tactile icons, reinforce notifications for deafblind users, and deliver non-visual cues in games, navigation, and media playback.
