The computer mouse has advanced over the years by trimming down a little, becoming optical, becoming more responsive and becoming wireless to name a few advances. The next step is to get rid of the mouse altogether and have an invisible mouse, also known as Mouseless.
The concept was created by Pranav Mistry along with Patti Maes and Liyan Chang and basically gets rid of the mouse completely.
By using an IR sensor with some custom software, the movements of a hand on a desk can be interpreted in to mouse and finger movement allowing users to simple glide their hand on a desk and tap the desk with their finger.
The IR sensor sits on the back of a laptop and detects movement to the side of the laptop. By skimming the IR beam across the desk the software can pick up where the signal is cut off and calculate where your hand is and move the mouse pointer appropriately.
The system costs just $20 to build which is interesting and would allow laptop users to more comfortably work as well as carry less around when out and about.
The video below shows a demonstration of how the software works and how accurate it is. It’s fairly impressive stuff and would be good for companies to adopt in the future.
