Mouse goes invisible

MIT scientists have worked out a way of making your mouse invisible, or at least not there at all.
Using the system user’s click and scroll exactly the same way they would with a computer mouse, without the device actually being there.

According to Wired you can pretend you have a mouse in your hand move it around the table and the cursor on the screen hovers. Tap on the table like you would click a real mouse, and the computer responds.

The project, called “Mouseless,” uses an infrared laser beam and camera to track the movements of the palm and fingers and translate them into computer commands.

Though new user interfaces such as touchscreens and voice recognition systems have become popular, the two-button mouse with scroll wheel still reigns supreme among computer users and is jolly difficult to replicate through technologies such as touch and speech.

With the Mouseless project, the infrared laser and camera are embedded in the computer. When a user cups their hand as if a physical mouse was present under their palm, the laser beam lights up the hand that is in contact with the table. The infrared camera detects this and interprets the movements.

It only costs $20 to build, and you never have to worry about it running out of batteries or filling up with nerk.
