Cell phones that shall not require you to use your fingers are already here. All you need to do is think and your wishes shall be carried out. NeuroSky Inc, a venture company based in San Jose, Calif, prototyped a system that reads brain waves with a sensor and uses them for mobile phone applications.

Software algorithms try to deduce from your brainwaves what you are thinking and pass on the appropriate commands to the cell phone. The concept is based on medical use of the same techniques. While the whole project currently requires several different parts, the company is planning on creating a single integrated chip to perform all the functions.

Neurosky recently exhibited their product in a working demo. One of the most interesting ones allows the user to move a video game character to an intended place as quickly as possible on the screen of a mobile phone. The more the degree of brain's concentration, the more quickly the character moves. Talk about using the force ; in no time we shall all be Jedis. For the demo, a Nokia handset was used which connected to the brain scanning headset via Bluetooth.
