By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Gan, Dayong (Beijing, CN), filed on June 7, 2012, was made available online on May 8, 2014.

The assignee for this patent application is Beijing Lenovo Software Ltd.

Reporters obtained the following quote from the background information supplied by the inventors: "In recent years, electrical devices with touch screen are rapidly developed. In such electrical devices, a touch sensing unit is generally arranged in stack above a display unit to form a touch display screen. By a user performing a gesture input such as touch or slide on the touch display screen, the electrical device is made to perform a corresponding operation.

"Generally, when the user performs a slide operation, the position of a start point of the slide gesture on the touch display screen is arbitrary. For the existing electrical devices, no matter whether the start point of the slide gesture is at an edge of the touch display screen or a central area other than the edge, the electrical device will equally handle it. In other words, the electrical device will not perform different operations according to the different the start points of the slide gesture.

"In addition, with development of the technology, processing ability of a processor is improved, and functions that can be provided by a portable electrical device for users are constantly increased. However, the type of the touch operation has a limit on the control type that can be performed by the user through the touch. Although in order to satisfy the continuous improvement of the requirement of touch control, many solutions have been proposed. For example, in these solutions, it is generally necessary for user to perform a relatively complex touch input, which demands the user a lot and may easily cause the misjudgment of the electrical device."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "In view of the above cases, the invention provides an electrical device and a touch input method thereof, which can perform different operations in accordance with different slide gestures (more particularly, edge slide operation and center slide operation), so as to facilitate the user to issue various operation commands with simple gestures and improve the user's experience. In addition, an object of embodiments of the invention is to provide an electrical device and a control method which can be applied to the electrical device so as to solve the above problems.

"According to an embodiment of the invention, there is provided a touch input method for a touch sensing unit, the touch sensing unit including an input area which is divided into a first area and a second area that are not overlapped with each other, and a first edge of the input area and a second edge of the second area being overlapped, wherein the second area can identify an input operation in which at least part of an operation object is in contact with the second edge, and the first area can identify an input operation in which the operation object is not in contact with the second edge, the touch input method comprising: detecting a gesture input; judging whether a start point of the gesture input is within the first area or the second area so as to generate a judgment result; generating a first command when the judgment result indicates that the start point of the gesture input is within the first area; generating a second command which is different from the first command when the judgment result indicates that the start point of the gesture input is within the second area; and executing the first command or the second command.

"The first command refers to an object operation command corresponding to the gesture input, the object operation command being used for operating the object, and the second command refers to a system administration command corresponding to the gesture input.

"An end point of the gesture input is within the first area or the second area when the start point of the gesture input is within the first area, or the end point of the gesture input is within the first area or the second area when the start point of the gesture input is within the second area.

"The second area refers to the edge of the first area and surrounds the first area.

"Said generating the system administration command corresponding to the gesture input further includes: identifying type of the gesture input; and generating a back command when the gesture input is identified to be a leftward slide operation in which the start point is within the second area.

"The input gesture refers to a gesture coming from outside of the touch area of the touch sensing unit.

"A length of the second border of the second area perpendicular to the first edge is less than a first distance and greater than a second distance, wherein when a physical touch imprint left by the finger is substantially identical to the first touch area sensed by the touch sensing unit, the touch sensing unit converts the first touch area to a first touch point and the distance from the first touch point to the first edge refers to the first distance, and when the physical touch imprint left by the finger is greater than the second touch area sensed by the touch sensing unit, the touch sensing unit converts the second touch area to a second touch point and the distance from the second touch point to the first edge refers to the second distance.

"The distance value from the divided boundary of the second area and the first area to the first edge of the input area of the touch sensing unit is less than the distance value from the first touch point to the first edge of the input area of the touch sensing unit corresponding to a case in which the edge of the first touch area is tangent with the first edge of the input area of the touch sensing unit.

"According to another embodiment of the invention, there is provided an electrical device comprising: a display unit for displaying an object of the electrical device on a display area; a touch sensing unit arranged above the display unit and used to detect a gesture input, a touch area of the touch sensing unit being overlapped with the display area of the display unit, the touch area being divided into a first area and a second area that are not overlapped with each other; a processor; wherein the processor is configured to: judge whether a start point of the gesture input is within the first area or the second area so as to generate a judgment result; generate a first command when the judgment result indicates that the start point of the gesture input is within the first area; generate a second command which is different from the first command when the judgment result indicates that the start point of the gesture input is within the second area; and execute the first command or the second command.

"The first command refers to an object operation command corresponding to the gesture input, the object operation command being used for operating the object, and the second command is a system administration command corresponding to the gesture input.

"The processor can be configured to: identify type of the gesture input; and generate a back command when the gesture input is identified to be a leftward slide operation in which the start point is within the second area.

"In the electrical device according to the embodiment of the invention and the touch input method thereof, by detecting the position of the start point the user's slide gesture and performing different commands in accordance with difference of positions of start point, it is possible for the user to manipulate the electrical device so as to execute various commands more easily, thus user's experience is improved.
