September 11, 2014



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 Luo, Yijun (Shenzhen, CN), filed on December 22, 2011, was made available online on August 28, 2014.

The assignee for this patent application is Zte Corporation.

Reporters obtained the following quote from the background information supplied by the inventors: "Currently, the application scope of the touch screen rapidly extends from a former commercial market for the minority, such as automatic teller machines of banks and industrial control computers, to the electronic field for public consumption, such as mobile phones, Personal Digital Assistants (PDAs), Global Positioning Systems (GPSs), Portable Media Players (PMPs) (such as MP3 and MP4), and even Tablet Personal Computers (Tablet PCs). Hopefully, the touch screen, of which the touch and control operation is simple, convenient and humanized, will become an optimum interface for human-machine interaction, and thus can be rapidly popularized.

"Touch screen inputting has advantageous, such as simple, convenient, humanized operation and the like, but also has disadvantageous: it is very difficult to perform precise click and location operations. For example, when inputting a text, one letter in a word is wrong, and the wrong letter is desired to be selected and amended. In this case, it is very difficult for operation, and it is easy to make a wrong selection. That is mainly because: the distance between letters is very small, and when a finger operates on the touch screen, the touching area between the finger and the touch screen is large. Moreover, when performing operations (such as click) with the finger, the finger covers the sight line of the user, so it is very difficult to perform a precise operation with the finger. Of course, the problem may be solved by using a handwriting pen, but carrying and using the handwriting pen also brings inconvenience to the user. Therefore, there is the problem that the user experience is not good when an operation is performed on the touch screen, as long as the distance between operation objects is very small."

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 this, the disclosure is intended to provide a method and device for implementing click and location operations on a touch screen, to solve the problem that it is difficult to precisely click and locate when the distance between operation objects is very small.

"To this end, a technique solution of the disclosure is implemented as followings.

"A method for implementing click and location operations on a touch screen is provided, which includes:

"a position relation between a touch point and a target point is set such that the touch point is separated from the target point;

"position information of the touch point is acquired;

"position information of the target point is calculated based on the position information of the touch point and the position relation between the touch point and the target point, and a position of the target point is displayed; and

"a confirmation operation is performed according to the displayed position of the target point.

"After the position information of the touch point is acquired, the method may further include:

"it is determined, according to the position information of the touch point, whether the touch point is located in an area where a precise click and location is required; and

"when the touch point is located in an area where a precise click and location is required, the position information of the target point is calculated based on the position information of the touch point and the position relation between the touch point and the target point.

"Before the confirmation operation is performed according to the displayed position of the target point, the method may further include:

"when it is determined, according to the displayed position of the target point, that the position of the target point needs to be fine-tuned, a touch object is moved and the position information of the touch point is re-acquired; and

"the position information of the target point is re-calculated based on the re-acquired position information of the touch point and the position relation between the touch point and the target point, and the re-calculated position of the target point is displayed.

"The process that the confirmation operation is performed according to the displayed position of the target point may include:

"the touch object leaves the touch screen, so as to confirm the position of the target point; or the touch object touches and then leaves the touch screen, so as to confirm the position of the target point.

"A device for implementing click and location operations on a touch screen is provided, which includes:

"a location information setting module configured to set a position relation between a touch point and a target point such that the touch point is separated the target point;

"a location information acquiring module configured to acquire position information of the touch point;

"a location information feedback module configured to: calculate position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point, and display a position of the target point; and

"an operation confirming module configured to perform a confirmation operation for a user according to the displayed position of the target point.

"The location information feedback module may be further configured to: determine, according to the position information of the touch point, whether the touch point is located in an area where a precise click and location is required; and when the touch point is located in an area where a precise click and location is required, calculate the position information of the target point based on the position information of the touch point and the position relation between the touch point and the target point.

"The location information acquiring module may be further configured to, when a user determines, according to the displayed position of the target point, that the position of the target point needs to be fine-tuned and when the user moves a touch object, re-acquire the position information of the touch point; and

"the location information feedback module may be further configured to re-calculate the position information of the target point based on the re-acquired position information of the touch point, and display the re-calculated position of the target point.

"The operation confirming module may further be configured to, when a touch object leaves the touch screen, confirm the position of the target point; or when the touch object touches and then leaves the touch screen, confirm the position of the target point.

"With the method and device for implementing click and location operations on the touch screen according to the disclosure, the position relation between the touch point and the target point is set such that the touch point is separated from the target point, so that the problem of covering the sight line of the user by the finger is avoided when the click operation or another operation is performed with a finger; the position information of the target point is calculated based on the position information of the touch point, and the position of the target point is displayed; and the fine-tuning can also be performed according to the displayed position of the target point. Therefore, the precise click and location can also be implemented even though the distance between operation objects is very small.
