JP4080498B2 - Control method of intelligent type movement of touch panel - Google Patents

Description

  The present invention relates to a control method for intelligent type movement of a touch panel.

  Currently, touch panels are widely applied to electronic products including portable computers, personal digital assistants, mobile phones or other electronic systems. A touch panel is an import device that is used to slide or touch a user's finger or a conductive article (eg, a touch pen) on the panel, which causes relative movement or absolute coordinate movement to the cursor, and other Supports extensibility function, eg key function simulation. In order to support more various functions in the operation area, there is a concept of section division, and a detection method for distinguishing the functions that the user wants to use is necessary.

  Advances in monitor and display card technology have allowed all computer systems to support screen menus of high resolution, eg, 1024 × 768 pixels. However, the size of the touch panel has practical limitations and does not provide such a high degree of analysis. For this reason, an intelligent type automatic edge scrolling function is already provided, and according to this, when the user reaches the boundary area of the touch panel, the cursor is automatically moved. In FIG. 1, the touch panel 10 is divided into two areas 12 and 14, and the area 14 is divided into eight blocks. When the user's fingers are moved to different blocks, the cursor automatically moves in different directions. When the user's finger 16 moves within the area 12, the touch panel 10 sends out the position information of the finger 16, and the cursor 18 on the monitor moves accordingly. When the finger 16 moves to reach the area 14, the touch panel 10 sends a scroll signal, and the cursor 18 is automatically moved in the corresponding direction by the block where the finger 16 is located. For the detailed contents of the intelligent type edge automatic scroll function, refer to Patent Document 1.

  Such an intelligent type edge automatic scrolling function sends a cursor movement signal every time the user's finger reaches the boundary area 14, so that the user wants to perform a general cursor movement, or intelligent type edge automatic scrolling. It is not possible to determine whether or not the user wants to perform the signal transmission, and an erroneous signal transmission is formed. For example, even if the user wants to move the cursor 18 along a locus as shown in FIG. 2, if the finger 16 inadvertently enters the area 14 while moving, the touch panel 10 sends a scroll signal accordingly. For this reason, the movement locus of the cursor 18 is modified as shown in FIG. In addition, since the area 14 is divided into 8 blocks, the cursor can move only in 8 directions, and the user's request to avoid restrictions on the moving direction cannot be satisfied.

  In addition, the area of the touch panel is reduced as the volume of the electronic product is reduced. However, when the touch panel is divided into a plurality of areas, inconvenience for the user is brought about.

  In addition, there is a demand for a control method that can activate intelligent type movement without defining a specific area on the touch panel and that is not subject to movement direction restrictions.

US Pat. No. 5,543,590

  An object of the present invention is to provide a kind of touch panel intelligent type movement control method, so that the touch panel can activate intelligent type movement without being restricted to a specific area and is not subject to movement direction restrictions. There is.

  According to the present invention, the intelligent type movement control method of the touch panel detects the position of the article on the touch panel, sends out the position information of the article when the article moves, and on the touch panel after the article moves. It includes a step of stopping and sending a movement signal when the stop time exceeds the reference time.

The invention of claim 1 detects the position of the article on the touch panel and generates coordinates of the position;
Detecting movement of the article and sending position information of the article;
Detecting a movement stop of the article and sending a movement signal when the stop time exceeds a reference time;
And the movement signal includes direction information, and the direction information is determined by the direction before the movement of the article is stopped .
According to a second aspect of the present invention, there is provided an intelligent type movement control method for a touch panel according to the first aspect, wherein the coordinates include absolute coordinates or relative coordinates .
According to a third aspect of the present invention, in the intelligent type movement control method for the touch panel according to the first aspect, the position information includes an absolute movement amount or a relative movement amount. It is said .

  According to the present invention, an intelligent type movement can be activated even if the touch panel does not define a specific area, the operation area of the touch panel can be increased, and the direction before the movement is stopped becomes the direction of the intelligent type movement. The convenience of operation can be increased.

  FIG. 4 is an operation flowchart of the embodiment of the present invention. Please refer to FIG. 4 and FIG. First, in step 20, the position coordinates of the touch of the finger 32 on the touch panel 30 are detected. Subsequently, in step 22, the movement of the finger 32 on the touch panel 30 is detected, the touch panel 30 sends out the position information of the finger, and the cursor 34 is moved accordingly. In step 24, when the movement stop of the finger 32 is detected and the finger 32 stops on the touch panel 30 exceeding the reference time, the touch panel 30 sends a movement signal and automatically points the cursor 34 in the direction before the movement stop. Move. Typically, the touch panel 30 includes a sensing line in the first direction and a sensing line in the second direction, the coordinates may be absolute coordinates, may be relative coordinates, and the position information may be an absolute movement amount. Or a relative movement amount. Among them, absolute coordinates are coordinate values generated with a fixed position (for example, the center point or one corner of the touch panel 30) as a fixed origin, and relative coordinates are relative positions (for example, a position where the finger 32 first contacts the touch panel 30). Is a coordinate value generated with reference origin, the absolute movement amount is the movement amount with respect to the fixed origin, and the relative movement amount is the movement amount with respect to the reference origin.

It is a display figure of operation on the known touch panel of fingers. It is a display figure of operation on the known touch panel of fingers. It is a display figure of operation on the known touch panel of fingers. It is an operation | movement flowchart of the Example of this invention. It is a display figure of operation on the touch panel which operated this invention of fingers.
