Abstract: Examples described herein may detect gestures using multiple antennas and/or using reflected signals transmitted by the device which is also detecting the gesture. Multiple antenna detection may allow for classification of 3D gestures around a device. The use of reflected signals transmitted by the device itself may reduce a need for a separate signal source to be used for gesture detection. Accordingly, in some examples, devices (e.g. mobile phones) may detect gestures performed on or around the device without a need to transmit any signal specifically designed for gesture detection. Signals already transmitted by the device (e.g. GSM signals) may be used to detect the gestures.
