Mobile device and wake-up method

The present invention relates to a mobile device, and more particularly to a mobile device that unlocks a hardware button with a specific gesture for unlocking.

In recent years, portable devices have become more advanced and more diverse in function. For example, handheld devices such as mobile phones or tablets can have telecommunications capabilities, send and receive email, maintain social networks, address book management, media playback, and a host of other functions and applications. Due to the diverse functions of these devices, these devices have become one of the necessities of life, and users perform activities ranging from simple telephone communication to various social activities and commercial transactions on the Internet. Because of this, the usage history records and various personal information stored on these handheld devices are becoming more and more important and diverse.

At present, there are a variety of handheld devices equipped with touch-sensitive display units (such as touch screens), and users can input them through the touch screen. When the user idles the electronic device for a period of time without using the electronic device, the electronic device automatically enters the sleep mode. When the user wants to use the electronic device again, the electronic device must first be unlocked to return the electronic device to the normal working mode for subsequent operations.

Generally, the unlocking action of the handheld device needs to be unlocked after the hardware button is enabled, and then the user can perform the unlocking by inputting a preset password on the touch screen or following the unlocking prompt displayed on the touch screen. the goal of. In the above unlocking program, whether it is a password memory or a complicated operation The steps all cause a burden on the user. For example, when the user unlocks the handheld device with only one hand operation, it is easy to cause the center of gravity of the handheld device to be unstable or slip while pressing the button, thereby causing inconvenience in use.

Next, in step S508, the touch processor 108 divides the summed value by a total number to obtain an average value, wherein the total number is a predetermined number minus one, that is, 3 (4 minus 1). Next, in step S510, the touch processor 108 multiplies the average value obtained in step S508 by a constant to obtain a determination value. It is to be noted that the constant is greater than or equal to 1 or an integer, such as 1, 3/2, 5/4, etc., and the invention is not limited. Next, in step S512, the touch processor 108 compares the largest one of the distances d1 with the determination value to determine whether the user gesture that generates the contact points constitutes a natural gesture. For example, when the judgment value is less than the largest one of the distances d1, the touch processor 108 determines that the user gestures that generate the contact points constitute a natural gesture. The flow ends in step S512.
