摘要

To prevent a user from sensing change in feeling of operation of a pointing device. There is provided a computer system control method for controlling a computer system having a coordinate designation system for producing base data for calculating position coordinates, the method comprising the steps of obtaining the position coordinates calculated based on the base data; when a predetermined application program is activated from another application program, obtaining position coordinates notified by the other application program, and showing a designated position image on a display screen based on the position coordinates obtained; and when the predetermined application program is activated from an operating system, showing the designated position image on the display screen based on the position coordinates obtained at the step of obtaining the position coordinates.

1. A computer system, comprising:
a coordinate designation system for producing base data for calculating position coordinates of a user controlled position image; at least one memory storing a first application program, a second application program, and an operating system for activating the first and second application programs, at least one processor operating under the control of the first application program to cause the computer system to function as: a first position coordinate unit operating to calculate position coordinates of the user controlled position image based on the base data in accordance with a first position coordinate computing algorithm yielding a first feeling of operation to the user when the user controlled position image is displayed, a first designated position image display unit operating to display the user controlled position image on a display screen based on the position coordinates calculated by the first position coordinate unit, an activating unit operating to permit the first application program to activate the second application program, and a notifying unit operating to notify the second application program of the position coordinates calculated by the first position coordinate unit when the second application program is activated from the first application program, and the at least one processor operating under the control of the second application program to cause the computer system to function as: a second position coordinate unit operating to calculate position coordinates of the user controlled position image based on the base data in accordance with a second position coordinate computing algorithm, which is different from the first position coordinate computing algorithm, yielding a second feeling of operation to the user when the user controlled position image is displayed, and a second designated position image display unit operating such that: (i) when the second application program is activated from the first application program, the user controlled position image on the display screen is based on the position coordinates received from the notifying unit and calculated based on the base data in accordance with the first position coordinate computing algorithm, and (ii) when the second application program is activated from the operating system, the designated position image on the display screen is based on the position coordinates calculated by the second designated position image display unit based on the base data in accordance with the second position coordinate computing algorithm.
