Video-to-Haptics

A class of techniques that automatically generate haptic feedback (typically vibrotactile or force cues) from visual content in video, so that viewers feel sensations synchronised with what they see. Video-to-haptics offers a non-visual channel for conveying motion, impact, and rhythm, and is a promising complement to audio description for blind and low-vision viewers of film, games, and live video. Approaches range from specialised pipelines keyed to specific actions (ball impacts, dance moves, first-person camera motion) to general methods that extract motion or saliency signals and map them to haptic actuators on phones, controllers, or wearables.
