The patented techniques enable Google to provide improved searches through additional information provided by radar-recognized gestures and physiological information. The techniques permit recognition of a great breadth of gestures and physiological information and in a robust set of circumstances.

Consider, for example, a case where a person is watching a television program on a computing device. Assume that the person sees a car being driven during the television program. The techniques described herein permit the user, with as little as an audio statement of “what kind of car is that?” or even “what is that?” and a gesture pointing at the television screen, to receive search results for the particular car shown on the television.

The radar field may be created by a smartphone or any other device in the vicinity.
