While the computer has made great leaps and bounds when it comes to ease of us, there are still certain segments of the population that find it difficult to use, especially the disabled. The Lomak (Light Operated Mouse and Keyboard) takes on an ingenious design for a computer input device, featuring a pointer that can be controlled via hand or mounted on one’s head. The light will point at a special input device that lets the user type a letter by moving one’s head slightly. I must say, don’t interrupt anyone using this. I know I would be pissed if I’m busy typing out a letter and turn my head to respond to a call, only to return to my document that now has an array of random letters strewn all over.
