"Google might have already patented some nifty eye-tracking controls, but that doesn't mean it isn't considering other sensory input. A recently granted patent hints at a potential glove-based controller, with references to a pair of detectors that record \"images\" of an environment, and then determine gestures based on the calculated movement between them. The illustrations go on to show a hand drawing out the letter J, indicating it could be used for text input, while another suggests recognition of pinch-to-zoom style gestures. There's no mention of its fancy glasses in the patent, but we're thinking a glove to control the Nexus 7 might be a bit overkill."^^<http://www.w3.org/2001/XMLSchema#string>
