Title:
GESTURE RECOGNITION WITH SENSOR
Document Type and Number:
Japanese Patent JP2023021967
Kind Code:
A
Abstract:
To provide a movement sensing apparatus and a high frequency motion sensing method that improve a sensor and processing for radio frequency sensing for gesture detection or recognition.SOLUTION: A sensor apparatus for motion or gesture sensing configured to emit radio frequency signals and pulses such as for pulsed range gated sensing includes a radio frequency transmitter and a receiver configured to receive reflected ones of the emitted radio frequency signals. The received pulses are processed by a motion channel and/or a gesture channel. The gesture channel produces signals for further processing for identification of one or more different motion gestures such as by calculating and evaluating features from one or more of the amplitude, phase and frequency of output signals of the gesture channel. The apparatus may optionally serve as a monitor for evaluating user activities, such as by counting certain activities.SELECTED DRAWING: Figure 3
