touch less keyboard : A new touchless keyboard for all of us who are physically impaired

Life sucks and sucks badly, but when you are physically impaired, any little thing like typing on a keyboard can become extremely difficult. And this is where the Japanese company Actbrise comes to our rescue with their new touchless keyboard.
To make it simple, the person who needs to use this keyboard needs to install a sensor on his/her head (or body), plug the touch less keyboard to their computer, and hang it over their PC screen. Once in position, each movement of your head will be transmitted to the keyboard and you will be able to start typing your text, or use your head as a mouse in order to navigate between windows or documents…
I must say that I am quite impressed by the simplicity of the system, but extremely sad to say, that the system will cost almost 1800€ !
