1. A system, comprising:
- a gesture detection assembly including;
a sensor cell array,a switching network configured to send signals independently to individual sensor cells of the sensor cell array, anda controller configured to control the switching network to send the signals at different frequencies to the individual sensor cells of the sensor cell array; and
a gesture recognition component configured to;
determine parameters of an object proximate the sensor cell array from responses of the individual sensor cells to the signals sent at the different frequencies, andidentify a gesture performed by the object using the parameters.

Abstract
The description relates to 3D gesture recognition. One example gesture recognition system can include a gesture detection assembly. The gesture detection assembly can include a sensor cell array and a controller that can send signals at different frequencies to individual sensor cells of the sensor cell array. The example gesture recognition system can also include a gesture recognition component that can determine parameters of an object proximate the sensor cell array from responses of the individual sensor cells to the signals at the different frequencies, and can identify a gesture performed by the object using the parameters.

10. A computer readable memory device or storage device storing computer readable instructions that, when executed by one or more processing devices, cause the one or more processing devices to perform acts comprising:
-
driving first individual sensor cells of a sensor cell array with first signals at a first frequency from a set of available frequencies; receiving, from the first individual sensor cells, first responses to the first signals sent at the first frequency; driving second individual sensor cells of the sensor cell array with second signals at a second frequency from the set of available frequencies; receiving, from the second individual sensor cells, second responses to the second signals sent at the second frequency; and identifying a gesture from the first and second responses. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system, comprising:
-
a sensor cell array; a switching network configured to send signals independently to sensor cells of the sensor cell array; and a controller configured to; select a first frequency for a first signal, identify an individual sensor cell of the sensor cell array to send the first signal at the first frequency, control the switching network to send the first signal at the first frequency to the individual sensor cell before controlling the switching network to send a second signal at a second frequency to the individual sensor cell or another individual sensor cell of the sensor cell array, and receive, from the individual sensor cell, a response to the first signal sent at the first frequency. - View Dependent Claims (17, 18, 19, 20)
