摘要:
The description relates to user control gestures. One example allows a speaker and a microphone to perform a first functionality. The example simultaneously utilizes the speaker and the microphone to perform a second functionality. The second functionality comprises capturing sound signals that originated from the speaker with the microphone and detecting Doppler shift in the sound signals. It correlates the Doppler shift with a user control gesture performed proximate to the computer and maps the user control gesture to a control function.

Systems and methods for sensing environmental changes using electromagnetic interference (EMI) signals are disclosed herein. An EMI monitoring system may be used to monitor an EMI signal of one or more light sources provided over a power line, e.g., in a home or building. The received EMI energy at the power line may be analyzed to detect variations in the EMI signature indicative of environmental changes occurring in the proximity of the light sources. Environmental changes that may be sensed include, but are not limited to, proximity, touch, motion, and temperature change.

摘要:
Examples of systems, devices, and methods are described herein that may provide for gesture recognition. Wireless communication signals may be received from sources in an environment (e.g. cellular telephones, computers, etc.). Features of the wireless communication signals (e.g. Doppler shifts) may be extracted and utilized to identify gestures. The use of wireless communication signals may accordingly make possible gesture recognition in a whole-home environment that may identify gestures performed through walls or other obstacles.
