Method and apparatus for detecting and interpreting path of designated position
First Claim
1. An information processing apparatus comprising:
- a display control unit configured to cause a touch screen display to display an image;
a detection unit configured to detect a plurality of touched positions which are multi-touched in the image displayed on the touch screen display by the display control unit; and
an interpreting unit configured to,in a case where it is detected that the plurality of touched positions detected by the detection unit remain stationary during a predetermined period, interpret a designation based on the touched positions as a first operation for determining a touched area enclosed by the plurality of touched positions within the image, andin a case where it is detected that the plurality of touched positions move, interpret the designation based on the touched positions as a second operation different from the first operation according to the movement of the plurality of touched positions.

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.

7. An operational method comprising:
-
displaying an image on a display screen; detecting a plurality of touched positions which are multi-touched in the image displayed on the display screen; interpreting, in a case where it is detected that the plurality of touched positions remain stationary during a predetermined period, a designation based on the touched positions as a first operation for determining a touched area enclosed by the plurality of touched positions within the image; and interpreting, in a case where it is detected that the plurality of touched positions move, the designation based on the touched positions as a second operation different from the first operation according to the movement of the plurality of touched positions.

8. A non-transitory computer-readable storage medium storing a manipulation program for controlling to perform manipulation, the program comprising codes for causing the computer to perform the steps of:
-
displaying an image on a display screen; detecting a plurality of touched positions which are touched in the image displayed on the display screen; interpreting, in a case where it is detected that the plurality of touched positions remain stationary during a predetermined period, a designation based on the touched positions as a first operation for determining a touched area enclosed by the plurality of touched positions within the image; and interpreting, in a case where it is detected that the plurality of touched positions move, the designation based on the touched positions as a second operation different from the first operation according to the movement of the plurality of touched positions.
