Method and apparatus for detecting and interpreting path of designated position
First Claim
1. A position information processing apparatus for processing position information comprising:
- designated position detector means for detecting a plurality of concurrently designated positions at a plurality of times, sequentially;
identifying means for identifying, each time the concurrently designated positions are detected, a corresponding one designated position, from among the plurality of designated positions detected at a preceding time, having an area closest in size to an area of each of the plurality of designated positions detected at a current time, by calculating the difference in size between each of the areas of the designated positions detected at the current time and each of the areas of the designated positions at the preceding time; and
travel path recognizer means for recognizing respective travel paths of the plurality of designated positions by recognizing each travel path which connects corresponding designated positions detected at the plurality of times.

Abstract
A method of detecting and interpreting a path of designated positions is disclosed. The method concurrently detects a plurality of designated positions on a touch panel, again detects the plurality of designated positions subsequent to a travel of the designated positions, determines the distances between each of the current designated positions and the respective immediately preceding designated positions, treats an immediately preceding designated position, closest to the current designated position of interest, as the immediately preceding designated position of the current designated position of interest, and acquires the path of each designated position, thereby recognizing the paths of the plurality of designated positions that move concurrently. A combination of the paths of the plurality of designated positions is interpreted to identify a designation input by a user, and an operation thus designated is executed.

5. A position information processing method for processing position information, comprising:
-
a detecting step of detecting a plurality of concurrently designated positions at a plurality of times, sequentially; an identifying step of identifying, each time the concurrently designated positions are detected, a corresponding one designated position, from among the plurality of designated positions detected at a preceding time, having an area closest in size to an area of each of the plurality of designated positions detected at a current time, by calculating the difference in size between each of the areas of the designated positions detected at the current time and each of the areas of the designated positions at the preceding time; and a travel path recognition step of recognizing respective travel paths of the plurality of the designated positions by recognizing each travel path which connects corresponding designated positions detected at the plurality of times.

6. A computer-readable storage medium storing a position information program for controlling a computer to perform processing of position information, the program comprising codes for causing the computer to perform:
-
an acquisition step of acquiring a plurality of concurrently designated positions at a plurality of times, sequentially; an identifying step of identifying, each time the concurrently designated positions are detected, a corresponding one designated position, from among the plurality of designated positions acquired at a preceding time, having an area closest in size to an area of each of the plurality of designated positions acquired at a current time, by calculating the difference in size between each of the areas of the designated positions detected at the current time and each of the areas of the designated positions at the preceding time; and a travel path recognition step of recognizing respective travel paths of the plurality of the designated positions by recognizing each travel path which connects corresponding designated positions acquired at the plurality of times.
