Abstract

PURPOSE:To smoothly execute the pointing operation of a character, etc., by providing a moving unit managing part for storing and managing a moving unit on the display screen of a cursor, and a display position managing part for determining the display position of the cursor, based on a data from the moving unit managing part, etc. CONSTITUTION:The titled driver is provided with a moving unit managing part 16 for storing and managing a moving unit on the display screen of a cursor which is operated in relation to a pointing device, and a display position managing part 17 for determining a display position of the cursor, based on a data from the moving unit managing part 16, etc. In this state, when there is a request for designating the moving unit, its moving unit is stored in the moving unit managing part 16. The display position managing part 17 moves the position of the cursor by the moving unit portion first, when the moving portion of the cursor, accompanied by the movement of the pointing device becomes the moving unit. In such a way, pointing of a character, etc. can be executed smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mouse and a tablet used for indicating a position on a display screen in a computer system.

This invention relates to drivers for pointing devices such as trackballs and electronic pens.

Conventional technology Conventional pointing device drivers include:
For example, there are drivers for pointing devices used in general personal computers. FIG. 4 shows a block diagram of this conventional pointing device driver, in which reference numeral 41 indicates a request input unit that accepts requests from other parts of the computer system and passes the requests to a processing unit to be described later; 42 is an input unit that receives a signal from a pointing device, converts the signal into data and passes it to a processing unit to be described later; 43 is a processing unit that processes information from each unit; and 44 is a display control that outputs display information regarding the cursor. Department.

In the conventional pointing device driver configured as described above, when the pointing device moves, data from the pointing device is processed by the processing unit 43 via the input unit 42 and displayed on the display screen. Data is output from the display control section 44 as the cursor moves continuously (in units of one dot). Alternatively, when a request to move the cursor position to an arbitrary position on the display screen is input from the request input unit 41, the request is processed by the processing unit 43, and data for moving the cursor position is sent from the display control unit 44. is output and the cursor position moves.

Problems to be Solved by the Invention However, with the above configuration, when a cursor is used to point to characters when editing a document, the size of the characters does not affect the movement of the cursor, as with a general character cursor. Since it is not a single movement, there is a problem in that the pointing operation for each character is not smooth.

In view of this, it is an object of the present invention to provide a pointing device driver that has a function of displaying a specified unit of movement of the pointing device.

Means for Solving the Problems The present invention provides a movement unit management section that stores and manages movement units on a cursor display screen, and a display that determines the display position of the cursor based on data from the movement unit management section, etc. This is a driver for a pointing device that includes a location management section.

Effects According to the present invention, with the above-described configuration, when a request to specify a movement unit is issued, the movement unit is stored in the movement unit management section. The display position management section moves the cursor position by the movement unit (discontinuous movement) only when the movement of the cursor becomes the movement unit as the pointing device moves. Therefore, pointing of characters, etc. can be performed smoothly.

Embodiment FIG. 1 is a block diagram of a pointing device driver in an embodiment of the present invention, and FIGS. 2 and 3 are diagrams showing display screens in an embodiment of the present invention. 1st
In the figure, 11 is a request input unit that accepts requests from other parts of the computer system and passes the requests to a processing unit to be described later, and 12 is a request input unit that receives signals from a pointing device and converts the signals into data. 13 is a processing section that processes information from each section; 14 is a display control section that outputs display information regarding the cursor; and 16 is a section that stores and manages the position of an area on the display screen. An area management unit; 16, a movement unit management unit that stores and manages the unit of movement of the cursor; and 17, a display position management unit that determines the display position of the cursor based on data from the area management unit and the movement unit management unit. It is. In Figures 2 and 3,
20°30 is the area in the display screen, and in Fig. 2, 21
22.23 is a cursor outside a specific area, and in FIG. 3, 31, 32.33 are cursors inside the area.

The operation of the pointing device driver of this embodiment configured as described above will be described below.

Here, it is assumed that characters are written inside the area 20.30, and the size of the characters is assumed to be the unit of movement of the cursor. Now 1. When specifying the unit of movement of the kerful within a specific area, a request for specifying the area and the unit of movement (in this case, the size of the characters) is input to the request input section 11. As a result, the respective data is stored and managed in the area management section 16 and movement unit management section 16. Next, when the processing unit 13 starts operating to update the cursor position, the display position management unit 17 updates the current position of the cursor obtained based on the information from the input unit 12. The area management section 16 is checked to see if it is in a specific area, and if it is not, pointing is performed as shown in 2-a to 2-b and 2-a in FIG.
Continuously move the cursor (
Data is sent to the display control unit 14 to move the dots (one dot at a time). On the other hand, when the cursor is within a specific area, the moving distance of the cursor that is proportional to the moving distance of the pointing device is determined by the movement unit (here, the character is the movement unit) stored in the movement unit management section 17. It is.

) from 3-a to 3-b and 3-a in Figure 3.
Data is sent to the display control unit 14 to move the cursor by the size of the movement unit as shown in FIG.

As described above, according to this embodiment, the cursor can be moved character by character within a specific area, and the cursor can be moved continuously in other areas.

In the embodiment, the interval between the managed area and the managed lattice point is one, but it may be two or more.

As described in detail, according to the present invention, the cursor can be moved in a certain movement unit within a specific area, which has great practical effects.
