The invention discloses a virtual electronic wall clock based on acoustic gesture recognition. The virtual electronic wall clock comprises a micro projection device, a microphone, a loudspeaker, a single-chip microcomputer, a protection plate, an arc-shaped plate and a main panel, wherein the micro projection device, the microphone and the loudspeaker are arranged in a groove of the arc-shaped plate; a lens of the micro projection device faces to the projection plate; the micro projection device, the microphone and the loudspeaker are successively connected to the single-chip microcomputer; the single-chip microcomputer is arranged on the main panel; the arc-shaped plate is connected to the main panel; the projection plate is connected to the main panel. Through the adoption of micro projection, the virtual electronic wall clock is achieved; the microphone is used for acquiring gesture acoustic characteristics of the loudspeaker; gestures of the user can be recognized; the user can operate the clock content by not directly touching the clock.
Description
technical field [0001] The invention relates to a virtual electronic wall clock, in particular to a virtual electronic wall clock controlled based on sound wave gestures. Background technique [0002] Traditional digital wall clocks and mechanical wall clocks have fixed content and a single style, and cannot easily change positions, seriously affecting user experience. At present, the multimedia application technology based on micro-projection is gradually becoming mature, and has broad application prospects in the military field, manufacturing field, education and scientific research field. At the same time, the human-computer interaction technology based on acoustic wave recognition receives ultrasonic signals through receivers, and creates a 3D environment based on the signal change characteristics of multiple locations to judge user gestures, so as to realize message transmission, which is an important development direction in the field of human-computer interaction. . ...
