Multi-Sensor Fusion Haptics

Multi-sensor fusion haptics combines computer vision, radar, ultrasound, and electromagnetic tracking with haptic feedback to create immersive tactile experiences in VR/AR. By fusing data from diverse sensors, these systems achieve submillimeter tracking precision and detect fine hand gestures and finger positions that single-sensor systems miss. Radar provides robust tracking through occlusions, while cameras offer visual detail, and the fusion compensates for each sensor's weaknesses.

The haptic component delivers precise force feedback, vibrations, or resistance to simulate touching virtual objects and feeling textures. Applications include VR gaming, surgical training simulations, industrial design, and accessible interfaces for visually impaired users. Advanced systems incorporate ultrasonic mid-air haptics for touchable holograms, wearable gloves with finger-level force feedback, and surface haptics that simulate textures on touchscreens.
