1. Field of the Invention
The present invention generally relates to applications of a touch screen, and more particularly, to a method for unlocking screen by using a touch screen, a mobile electronic device using the same and a storage medium thereof.
2. Description of Related Art
Along with the progresses of science and technology, it may not be possible to meet the demands of customers by merely integrating multiple functions into an electronic device. In fact, a fully-functional electronic device must satisfy not only the requirements of compact shape and nice look, but also operation convenience so as to meet the increasing critical demand of customers. Taking a handset widely used around the world today as an example, it used a hardware keyboard as the input interface in the early stage thereof. However, along with the emergence of touch screen, due to many features of a touch screen, such as usage convenience, visual operation, durability and low cost, the handset manufacturers are using a touch screen to replace the traditional hardware keyboard for promoting the operation convenience of handset.
Although a handset using a touch screen for operation is very convenient, but the manufacturers need to develop a new special mechanism used in a handset to prevent a user from accidentally touching the screen to start any unwanted function. In other words, when a user does not operate the handset, the handset would automatically enter a screen locking state, and thereby disable the inputting function of the touch screen. The above-mentioned mechanism is particularly vital when the handset of a user is put in the pocket or the backpack. Once the handset has such a mechanism and the user sets the handset as screen locking state, the user would never worry about accidental touching of the screen, for example, a phone call is accidentally dialled up.
In terms of a smartphone equipped with an embedded Microsoft Windows mobile OS (operation system), an icon showing screen locking state can be illustrated on the host operation frame of the screen, and the user can click the icon to activate the screen locking state. However, after unlocking the screen, the user needs to follow the instruction on the host operation frame to click the icon or item on the screen step by step, so that the smartphone returns back the state for accepting general operations. The above-mentioned unlocking screen scheme takes more operation time. In particularly, considering the icon or the item to unlock screen usually is not big, therefore, the user may experience wrongly clicking situations so that the operation of unlocking screen can not be completed quickly.
Accordingly, the present invention is directed to a method for unlocking screen, which is able to close the locking screen function according to a touching and sliding manipulation on a screen provided by a user so as to increase the convenience of exiting screen locking state.
The present invention is also directed to a mobile electronic device, which is able to provide a more visual manipulation for a user to unlock the touch screen of the mobile electronic device.
To achieve the above-mentioned or other objectives, the present invention provides a method for unlocking screen for disabling screen locking state of a mobile electronic device. The mobile electronic device herein has a touch screen. The method includes: defining at least two signal input areas on the touch screen; calculating a moving range of a trajectory produced by an input signal when the input signal is detected within at least one of the signal input areas; when the moving range reaches a predetermined value, unlocking the touch screen of the mobile electronic device.

Other objectives, features and advantages of the present invention will be further understood from the further technological features disclosed by the embodiments of the present invention wherein there are shown and described preferred embodiments of this invention, simply by way of illustration of modes best suited to carry out the invention.
The above-described and other technical descriptions, the features and the functions of the present invention are clearly presented in association of the detail depiction of an embodiment with the accompanying figures.
In order to more clearly disclose present invention, several embodiments are depicted in follows.
Except for displaying the operation frames of various application programs, the touch screen 110 herein further includes at least two signal input areas, and each of the signal input areas receives an input signal produced by touching actions of a user.
The moving range calculation module 120 is connected to the touch screen 110 for calculating a moving range of a trajectory produced by the input signal when the input signal is detected within one or more of the signal input areas.
The processing module 130 is connected to the touch screen 110 and the processing module 130 is for unlocking a screen locking state of the mobile electronic device 100 when the moving range calculated by the moving range calculation module 120 reaches a predetermined value.
To explain how the mobile electronic device 100 originally in the screen locking state disables the screen locking state through the operations of the touch screen 110, the moving range calculation module 120 and the processing module 130, the following is exemplarily depicted.
In an embodiment, the touch screen 110 split by the processing module 130 is shown by the one of
Then, in step 220 as shown in
In step 230, the processing module 130 judges whether or not the moving range reaches the predetermined value. In the embodiment, the moving ranges calculated by the moving range calculation module 120 includes a horizontal component and a vertical component, and the processing module 130 judges whether or not the vertical component of the moving range reaches the predetermined value. If the vertical component of the moving range reaches the predetermined value, as shown by step 240, the processing module 130 would disable the screen locking state of the mobile electronic device 100. In another embodiment however, the horizontal component is taken as the base to judge whether or not the horizontal component exceeds the predetermined value so as to disable or remain the screen locking state, which the present invention is not limited to.
It can be seen from the described above since the processing module 130 defines two signal input areas on the touch screen 110, thus, the user can use an input tool to touch the blocks 115 or 119, or both the blocks 115 and 119, on the touch screen 110 to produce an input signal. When the user moves the input tool to make the moving range reach the predetermined value, the processing module 130 automatically closes the screen locking function of the mobile electronic device 100 so as to allow the user conducts general manipulations on the mobile electronic device 100.
Next, in step 420, a first input signal and a second input signal are simultaneously detected within the two signal input areas (the blocks 115 and 119), the moving range calculation module 120 starts respectively calculating the moving range of the first trajectory produced by the first input signal and the moving range of the second trajectory produced by the first input signal, wherein the above-mentioned first trajectory and second trajectory have the same moving directions or two opposite moving directions, which the present invention is not limited to.
In step 430, the processing module 130 judges whether or not the moving range reaches the predetermined value. As shown by step 440, when the moving range reaches the predetermined value, the screen locking state of the mobile electronic device 100 is disabled. In an embodiment, once one of the moving ranges of the first trajectory and the second trajectory reaches the predetermined value, the processing module 130 would disable the screen locking state of the mobile electronic device 100. In other words, the user can use two fingers to simultaneously touch the blocks 115 and 119 on the touch screen 110; once the displacement of one of the fingers on the touch screen 110 reaches the predetermined value, the mobile electronic device 100 would close the screen locking state.
In another embodiment, the processing module 130 would close the screen locking state of the mobile electronic device 100 only both the moving ranges of the first trajectory and the second trajectory reach the predetermined value. In other words, after the user uses two fingers to simultaneously touch the blocks 115 and 119, and the moving ranges produced by the two fingers on the touch screen 110 simultaneously reach the predetermined value, the screen locking state of the mobile electronic device 100 can be disabled.
In the embodiment of
Note that the above-described method for unlocking screen can be executed by any mobile electronic device having a processor. The above-mentioned embodiments can be further designed to include a plurality of program codes, and a storage medium readable by a computer (for example, optical disk, diskette and removable hard disk) is used to store the computer program. After loading the computer program to a mobile electronic device, the mobile electronic device can execute the method for unlocking screen as the described above embodiments.
In summary, the method for unlocking screen, the mobile electronic device and the storage medium thereof provided by the present invention through defining two or more than two signal input areas on the touch screen and detecting an input signal within the at least one signal input area so as to calculate the moving range of the trajectory of the input signal. The present invention decides whether or not to disable the screen locking state of the mobile electronic device according to whether or not the moving range reaches the predetermined value, and thereby provides the user with a more varied scheme to close the screen locking function.
