TECHNOLOGY.... TODAY ,TOMMORROW.....

        Nowadays can you imagine a mobile phone without a touch screen?The technology has so evolved such that the minimum requirement in today's mobile phone is a touch screen. Ohh....sorry recently touchscreen has started shifting its place to almost all the systems that are under human control. However, Texas A&M University's Interface Ecology Lab is working under a very promising technology- Zero Touch.

The Future Technology

       Zero Touch is not like other touch screens which are neither capacitive nor resistive (or any other type). Zero Touch screen is on the principle that a series of light will be projected across the screens by a number of Infrared (IR) sensors and Infrared (IR) LEDs. And the screen is touched when there is an interruption to these "invisible" light beams. Now these interruptions can be visualized to create a visual hull of any objects in the frame of these IR sensors.
        However, this concept is very much similar to capacitive touch screens where any interruption in the electrostatic field is considered as some kind of interaction with the screen. After all this is going to be much more interesting when it comes to real world.

Who knows in future whether the electronic systems touch you one day and wait for its processing....
