Gesture-wakened electronic device and gesture wakening method thereof

Abstract

The invention discloses a gesture-wakened electronic device and a gesture wakening method thereof. The gesture-wakened electronic device comprises a sound generator, a sound receiver, a filter, a gyroscope, an accelerator and a controller. The sound generator transmits sound wave; the sound receiver receives an acoustic positioning detection signal reflected by a moving object; the signal is filtered by the filter to remove background noise. The controller judges current motion state according to the gyroscope and the accelerator. The controller calculates changes in displacement of the moving object according to time of sound wave propagating in the air when in the current motion state of the electronic device; the controller recognizes a motion pattern of the moving object according to the changes in the displacement; if the motion pattern matches with an appointed device wakening pattern in a motion pattern mapping command base, the electronic device is wakened to run. The gesture-wakened electronic device and the gesture wakening method thereof have the advantages that control convenience level is increased, user experience is improved, the gesture recognition technology is combined with the gyroscope and the accelerator, frequent waking of the device caused by maloperation or misjudgment is avoided, and standby power consumption is optimally balanced.

Description

technical field [0001] The invention relates to a method for waking up an electronic device by a gesture. Background technique [0002] As mobile devices play an indispensable role in the daily work and life of human beings, waking up the device, turning on the screen or putting the device into standby mode is the most frequent operation of the final consumer every day. According to statistics, a deep smartphone user can wake up the phone and light up the screen more than one hundred times a day. For ordinary Android mobile phones, the traditional control method for waking up the mobile phone is for the user to press the power button of the mobile phone. The disadvantage of this operation is that the position of the power button is not uniform, and it is difficult for consumers to adapt; in addition, with the increasing size of smart phones The bigger the phone is, the more you need to move up and down with one hand or even cooperate with both hands to wake up the mobile ph...
