Motion-based gestures patent filed by Google
Flow chart for Google's hands-free system
The hands-free concept has been done before. The Pantech Vega LTE, sold only in Korea, uses its front-facing camera to allow users to make a waving gesture to answer a call, flip an ebook page, browse pictures in the gallery or change a song. Check out the video below to see how the phone works. And while not important to its hands-free use, we should also point out that the Pantech Vega LTE offers a 4.5 inch LCD display with one of the highest pixel density counts we have seen at 335ppi.
With all of the patent battles going on, the first to get new technology protected is more important than ever. A promising technology that allows handset owners to control their device hands-free seems almost destined to be in use in a wide number of handsets in the not too distant future. The question then will be whether or not Google gets to collect the toll for use of the highway, or if manufacturers of non-Android handsets try to take a ride for free.
