We all know Pranav Mistry, the inventor of Sixth Sense technology, now he is working on technology that will convert your regular monitor into touch screen monitor, the technology is called as ‘PreCursor’.
Watch this Video for a Demo of PreCursor technology
Precursor create an invisible layer that hovers in the front of your screen, this layer is created using 2 cameras and one infrared laser. With mouse there are 3 level of interactions, i.e. Hover, click and double click. But current touch screen technology is limited to one level only. Precursor adds more level to touch interaction . When your fingers interrupt the plane, the reflected light will be detected by the 2 cameras and blob will be interpreted
Precursor is still in labs but this technology has great potential, it has potential to expand beyond basic computer screen
