This document describes techniques and devices for non-visible radar-based gesture recognition. Through the use of the techniques and devices described herein, users can control their devices through in-the-air gestures, even when the gestures are not within the line of sight of the sensors of their device. . Thus, the techniques may be to lower the temperature in the room when the user is obscured by the thermostat's gesture sensor, increase the volume of the media player when the user is in a different room than the media player, or the user's gesture to a chair, sofa, Or, in many situations where control is required but conventional techniques do not allow effective control, such as pausing a television program when covered by other obstacles, allow users to control their devices.
