Gesture detection and interaction techniques are described. Object detection used to support the gestures may be accomplished in a variety of ways, such as by using radio waves as part of a radar technique. In a first example, the techniques are implemented such that one hand of a user sets a context for a gesture that is defined by another hand of the user. In another example, a gesture recognition mode is utilized. In yet another example, detection of distance is used such that the same motions may be used to different between operations performed. In a further example, split gestures are supported. In another instance, entry into a gesture recognition mode may be implemented through touch and then recognized through three-dimensional orientation and motion of that hand or another.

The computing device of claim 9, wherein the first orientation and movement of the first hand of the user are usable to disambiguate the second orientation and movement of the second hand of the user as corresponding to different said gestures when the second orientation and movement of the second hand of the user matches the first orientation and movement of the first hand. 12. The computing device of claim 9, wherein the housing is configured to be worn or carried by the user. 13. The computing device of claim 9, wherein the housing is part of an automobile, television, or desktop computer. 14.
