Patent Hints at Laser-Controlled Google Glasses

With Google's Project Glass still very much in its awkward developmental stages, the best method of controlling it remains up for debate. This patent, though, suggests that a laser-projected control pad might be in the running.

Currently, Project Glass uses a touch pad that runs down the side of one of its arms. Trouble is, that means reaching up every time you need to adjust a setting. This idea, though, would use a laser projector to throw a control pad onto any surface that you're looking at: wall, desk, arm, whatever. Then, a small camera would interpret finger movements in the region of those buttons and turn them into commands. Simple.

This is well-trodden ground, of course: there have been oh-so-many laser projectors designed to throw a keyboard onto a desk in front of you. But they were static; Google's offering would be much trickier to pull off and use. More here.
