Haptic technology the texture of clothes for sale on the internet. Future advancements in haptic technology may create new industries that were previously neither feasible nor realistic. Researchers at the University of Tokyo are working on adding haptic feedback to holographic projections. The feedback allows the user to interact with a hologram and receive tactile responses as if the holographic object were real. The research uses ultrasound waves to create acoustic radiation pressure, which provides tactile feedback as users interact with the holographic object. The haptic technology does not affect the hologram, or the interaction with it, only the tactile response that
Haptic technology by a fingertip, as a programmable function of the finger's motion. The TPaD Tablet Project uses an ultrasonic technology to modulate the slipperiness of a glass touchscreen, as if a user's finger is floating on a cushion of air. In February 2013, Apple Inc. was awarded the patent for a more accurate haptic feedback system that is suitable for multitouch surfaces. Apple's U.S. Patent for a "Method and apparatus for localization of haptic feedback" describes a system where at least two actuators are positioned beneath a multitouch input device to provide vibratory feedback when a user makes contact with the
