Pointing device and method of control of same

摘要

The pointing device is usable for moving a pointer or a cursor on a display of a computer (32; 140; 421) to any position of the display (21), characterized by being comprised of a slider (1) which can move in at least an X direction and Y direction. A detector (9a, 9b) detects the position of the said slider in the X direction and Y direction along with its movement. A processor (CPU) which has a position information memory (MRY) successively stores position information obtained by said detector at predetermined timings and a vector processing unit (VEC) and compares the latest position information and the preceding position information stored by said position memory so as to compute the relative positional relationship of the two and outputs a signal for moving the cursor or pointer on the display based on the results of the same.
