Towards holograms that can be seen, touched and felt

Research by the computer science department of the University of Bristol in the UK, could change the way we view and interact with virtual objects in three dimensions.

This new technology could, for example, allow surgeons to explore the results of 3D scanner, allowing them to feel the internal organs as if they were real.

This technology uses ultrasound to provide haptic feedback (ie a force feedback) to the user. Associated with a holographic display system, it could see, touch and feel the fingers invisible virtual objects and non-palpable in reality.

Managing precisely the issue of these ultrasound, researchers can create disturbances in the air that can be felt and interpreted as complex 3D shapes by the user.

In the future, we may well feel virtual materials and feel their shape under our fingers. Interesting to be able to manipulate objects in museums ...
