When the user wants to draw a horizontal line by determining the start and end points of the horizontal line by clicking a button on the pointing device 1, the user first selects the cursor movement direction input means 2 to change the cursor movement direction of the pointing device 1 in all directions. Specify.

Then, the cursor movement direction input means 2 inputs movement direction instruction data (step 21), and stores the input movement direction instruction data (step 22).

In this state, when the user moves the pointing device 1 to determine the starting point of the horizontal line, the input control processing means 3 is activated.

The input control processing means 3 determines that the manually entered data is coordinate data (step 31), and checks the movement direction instruction data stored in the cursor movement direction input means 2 to confirm that the cursor movement direction is omnidirectional. In step 321), it is determined that X and y are
Both coordinates are updated (step 322), and the cursor control processing means 4 is activated (step 33).

The cursor control processing means 4 erases the current cursor on the screen of the CRT display 6 (step 41), and displays a new cursor at the new X and y coordinates updated by the input control processing means 3 (step 41). 42).

After the processing by the cursor control processing means 4, the input control processing means 3 activates the information notification processing means 5 (step 34).
