Over the years, the mouse has evolved. First wired and connected through Bluetooth, it ended up with a half-dozen buttons to eventually take over the multicast. If for some future pass through touch screens, the mouse has not said its last word and now she makes us hocus-pocus.
The Mouseless (read "without a mouse") is visible, or rather, it does not. Over the last truly is emulated by your own fingers. Pranav Mistry, currently a research assistant at MIT Media Lab, has developed a device consisting of an infrared laser and a camera filming the hands of the user. Thereafter each finger movement is interpreted and associated with the mouse cursor on the screen. The click is also analyzed and transformed into action.
Pranav Mistry added that the prototype has been manufactured for about $ 20. Here is a video presentation.
