Light-operated computing: Lomak

A different kind of keyboard and mouse replacement, the Lomak is considered so innovative that it's earned a spot in New York's Museum of Modern Art. Art with a purpose, Lomak stands for "light operated mouse and keyboard," and for those without the use of their hands, it can mean freedom to compute on their own.

The system uses a head-mounted device that shoots a laser beam to a keyboard replacement that has 105 photo-sensitive spots arranged in circles that correspond to letters and numbers, punctuation and mouse movements. When the user aims the beam at what she wants and moves the beam to the Confirm button at each circle's center, Lomak carries out the command. (There's also an LED hand pointer for those with limited hand movement.)

Not only does Lomak work with Macs and Windows machines, but unlike other keyboard replacements, it doesn't require calibration or any extra software. Made by New Zealand-based Opdo, a complete Lomak setup costs $2,500.
