You don't need us to tell you how this could change the adult-entertainment business beyond recognition
A 3D image you can touch. Is your heart now pounding with excitment? Is your imagination running at 1000 miles-an-hour?
So are the imaginations of a group of Japanese scientists, who claim to be using Nintendo Wii Remotes and ultra-sound techniques to create a vaguely touchable sort of 3D display.
A holographic image has been augmented with sensors that detect when someone's hand is moving through it, allowing the computer brain behind it all to fire off a command to activate a touch sensor. A couple of off-the-shelf Nintendo Wii Remotes are used to relay the position of the user in 3D space, with ultrasonic waves apparently able to produce a convincing enough form of tactile feedback when the user "touches" the hologram.
As ever, there's a boring a serious reason behind the research - it could be used in hospitals to help patients turn on holographic light switches.
Not sure why people in hospitals would need holographic lights, though. The poor people are probably confused and bewildered enough already, without having to work out what's real, what's a medication-induced hallucination, and what's a bloody hologram.
Oh. Apparently it's to avoid contamination.
