Haptic Telescope is a vibro-tactile haptic display designed to map information in a moving visual field to meaningful haptic cues by extracting spatial and frequency changes in the optical flow and modulating them to a high-bandwidth tactile actuator array. Haptic Telescope can simulate the changes in the visual field relative to an observer, combining both spatial changes and frequency variations of tactile actuators. Visually consistent objects with large optical angles (low spatial frequency) are mapped to the haptic domain as low frequencies and small optical angles (fast spatial frequencies) are mapped as high frequencies. Haptic telescope is capable of giving pseudo remote touch sensation along with enhanced motion perception.
