Tactile holograms are a touch of future tech
- ByStartupStory | September 29, 2021
The idea of touchable holograms is familiar to millions from its appearance in sci-fi favourites like Star Trek’s holodeck, where characters can interact with solid-seeming computer simulations of people, objects and places. To the merriment of sci-fi lovers, researchers from the University of Glasgow have developed a new way to create the sensation of physically interacting with holographic projections. They have termed this new technique they have developed as “aerohaptics”.
The system pairs volumetric display technology with precisely controlled jets of air to create the sensation of touch on users’ hands, fingers and wrists. The technique could form the basis of new ways to interact with virtual objects, advanced forms of teleconferencing, and even empower surgeons to perform procedures remotely. The system, developed by the University’s Bendable Electronics and Sensing Technologies (BEST) research group, is based around a pseudo-holographic display that uses glass and mirrors to make a two-dimensional image appear to hover in space—a modern variation on a 19th-century illusion technique known as Pepper’s Ghost.
