Input data processing program and input data processing apparatus
First Claim
1. A computer-readable storage medium having stored thereon an input data processing program which causes a computer, having a detecting device that detects input positions on an input surface at intervals of a predetermined time period, to execute:
- storing, as a reference point position, an initially detected input position among a series of input positions which are continuously detected, in a memory of the computer;
updating the reference point position so as to move the reference point position from the initially detected input position toward a predetermined target position, wherein the predetermined target position represents a center of the input surface;
calculating, when each of the series of input positions is detected, an operation vector connecting between an input position having been most recently detected and the reference point position stored in the memory; and
performing a predetermined process using a magnitude and a direction of the operation vector.

Abstract
An information processing apparatus stores a series of input positions which are continuously detected by an input device in a memory thereof in order of the detection. An input position (B1) initially stored in the memory is stored as a reference point position in the memory. When each of the series of input positions is stored in the memory, an operation vector (vector v′1) connecting between an input position having been most recently stored in the memory and the reference point position in the memory is calculated. The information processing apparatus performs a predetermined processing using a magnitude and a direction of the operation vector. The reference point position stored in the memory is updated to a position obtained when the reference point position is moved toward a predetermined target position (point A) when each of the series of input positions is stored in the memory.
