Embodiment Construction

[0016] refer to figure 1 Shown is the operating environment diagram of the preferred embodiment of the portable electronic device unlocking system of the present invention.

[0017] In this embodiment, the portable electronic device 1 includes an unlocking system 10 , an acceleration sensor 11 , a processor 12 and a memory 13 . The unlocking system 10 presets unlocking patterns for unlocking operations and stores them in the memory 13 . For example, the unlocking graphics are characters and graphics, wherein the characters can be various text symbols, and the graphics can be plane or three-dimensional graphics. The acceleration sensor 11 is used to sense the acceleration of the portable electronic device 1 , and the unlocking system 10 obtains the acceleration of the portable electronic device 1 from the acceleration sensor 11 , and decomposes it to calculate its displacement in each moving direction. When the preset unlocking operation is a character or a plane figure, the ...

Abstract

The invention provides a system and a method for unlocking a portable electronic device, wherein the method comprises the steps of obtaining the acceleration of the portable electronic device, calculating the time of duration, from non-zero to zero, of the acceleration of the portable electronic device, decomposing the obtained acceleration in each set axis to obtain the moving direction of the portable electronic device in each axis, calculating the displacement of the portable electronic device moving in each set axis according to the obtained acceleration, the obtained time of duration and a displacement calculation formula, drawing an unlocking graph according to the displacement of the portable electronic device moving in each decomposition direction, determining whether the drawn unlocking graph is the same as a predetermined unlocking graph, and if the drawn unlocking graph is the same as a predetermined unlocking graph, executing the operation of unlocking. The system and the method are capable of sensitively controlling the unlocking function of the electronic device through interesting graphic unlocking operation without damage to the screen and leakage of important data of the electronic device.

Description

technical field [0001] The invention relates to an electronic device unlocking system and method, in particular to a portable electronic device unlocking system and method. Background technique [0002] Currently, popular portable electronic devices on the market, such as mobile phones, MP4 players, and handheld computers, generally have so-called screen locks or keyboard locks to avoid unnecessary erroneous operations. Commonly used unlocking methods include single button unlocking, combination button unlocking, touch screen click to unlock, dragging the touch screen to unlock and so on. With the widespread use of touch screens, touch-type unlocking of portable electronic devices is more widely used, while key-press unlocking is gradually weakened. [0003] Touch-type unlocking needs to click the touch screen to perform corresponding operations, which is simple and convenient. However, too frequent touch operations may easily cause scratches on the screen. In addition, if...
