TECHNOLOGIES FOR RADIOFREQUENCY TOUCH AND GESTURE RECOGNITION

Abstract:

Techniques for radiofrequency (RF) touch and gesture recognition are disclosed. In the illustrative embodiment, RF transmitters and receivers are connected to data lines and gate lines of a display. RF signals sent on one data or gate line may be scattered to a different data or gate line based on the presence of a nearby object, such as a finger. The amount of scattering on different data or gate lines can be used to determine a location of one or more objects.
