Microsoft developed a 3D touch screen. It consists of a liquid crystal display screen. This comes with both force detectors and a robotic arm. By making it move back and forth the robotic extension creates an illusion of surface texture. The resistance to a user’s fingertip is mimicked thereby simulating the form and weight of an object. The images you see on screen can thus be virtually touched and moved around here and there. According to BBC News, the use to which this delightful device can be put includes medical diagnosis of MRI scans. It can also be incorporated into the structure of the video games of the future. The user’s finger simply touches the screen and from there onwards a magical journey ensues. The senses of touch and sight merge stereoscopically.
As long as the convergence is correct and the visuals are constantly changed, an eerie perception of depth is possible. The human brain which is a marvelous tool can be fooled by this high tech wonder into taking the virtual reality for granted. A medical doctor may feel the ridges and lobes in an MRI scan of a human brain. He can gain more practical information via this mechanism than by merely looking at the images. Tumors can be detected easily this way by sensing the difference between soft tissues and hard tissues. However, senior physicians have their doubts. One of them spoke of how the real world is quite different from a simulated version of it. In real life textures and shapes change rapidly and unpredictably. This is a far cry from the world of VR which is still a long way from the cold hard reality of everyday life.
The ultimate goal of this effort by Microsoft is to do for touch what fancy graphics have done for eyesight. It’s a bold attempt alright. Basically, you touch the device which pushes back with its delicately balanced force feedback system. Scientists have so far been able to allow users to feel the surface features of a cup and ball on the device. Users have to wear 3D glasses to enable stereoscopic vision. The device can even be employed as a Braille reader for the blind. This is very practical and would open up a whole new world for the visually impaired. Undoubtedly, the technology has a host of important uses which will manifest themselves as the future arrives in its majestic grandeur.
