Operation method of handheld electronic device

Abstract

The invention provides an operation method of a handheld electronic device. When the handheld electronic device moves, a mobile sensor is started; while a central processing unit detects a signal of the mobile sensor, a timing unit is started; the central processing unit receives a first signal group generated by the mobile sensor within a first time interval; when the central processing unit judges that the handheld electronic device finishes shake for the first time according to the first signal group and a shake judging program, the timing unit starts to count a second time interval; in the second time interval, the central processing unit detects the signal of the mobile sensor and receives a second signal group generated by the mobile sensor within the first time interval; and when the central processing unit judges that the handheld electronic device finishes shake for the second time according to the second signal group and the shake judging program, the corresponding function of an application unit is started. By the device, error judgment can be reduced and the functions of shaking for two times are more correct and convenient.

Description

technical field [0001] The present invention relates to an operating method of a hand-held electronic device, in particular to an operating method that correctly judges that the hand-held electronic device is shaken twice to start software. Background technique [0002] Handheld electronic device operation technology has developed rapidly in recent years. In addition to using keyboard input or touch screen input, the application of detecting the movement of the mobile phone's built-in motion sensor (motion sensor) to operate the handheld electronic device is even more important. is thriving in diversity. For example, US Patent Publication No. US20090280860 discloses a method of using a mobile phone's motion sensor to detect a state of rotation or rapid shaking, and then activate the corresponding phone function. [0003] In the prior art, there is a design that allows the handheld electronic device to have the function of "shaking twice", that is, when the user shakes the h...

Problems solved by technology

[0004] The principle of "shake twice" is that the central processing unit of the handheld electronic device determines whether to send an activation signal to the software application layer by continuously receiving two activation signals sensed by the motion sensor within a predetermined period of time. ,like figure 1 As shown, when the user tilts the handheld electronic device to one side and shakes it twice along paths A and B (like the above-mentioned two quick swings to one side), the output signal is used to determine whether there are two consecutive Shake, because the sensitivity of the motion sensor will be highly positively correlated with the number of signals sent, ideally, when the user uses "shake twice", the central processing unit can only judge that two groups of motion are received. After receiving the signal from the sensor, start the software function. However, in order to avoid missing the signal sent by the motion sensor, the sensitivity of the motion sensor will be set relatively high in practical applications for more sensitive detection. The sensitivity of the mobile sensor has been fixed and cannot be changed, so it is possible that due to the high sensitivity, even if the user only performs two shaking actions, the central processing unit judges multiple start signals; in addition, it is possible to use The operator accidentally touches the hand-held component, causing unnecessary triggering of multiple start signals, resulting in misjudgment results

Sometimes because the hand-held electronic device is placed in the backpack, when the user walks with the backpack on his back, or when the user picks up the hand-held electronic device and rides a car, the hand-held electronic device may receive a sense of movement when the car is driving on a bumpy road. multiple signals from the tester, resulting in false activation of the "shake twice" function
