INFORMATION PROCESSING DEVICE HAVING TOUCH SCREEN
First Claim
1. An information processing device provided with a touch screen having a touch panel attached thereto, comprising:
- a contact detector that detects a contact position and an area of contact when there is a touch operation on the touch screen;
a region identifier that identifies a region on the touch screen that has been touched among a plurality of regions defined on the touch screen, said region being identified on the basis of the contact position detected by the contact detector; and
a controller that compares an area of contact detected by the contact detector to a threshold set in accordance with the region on the touch screen when said region is identified by the region identifier, the controller interpreting the touch operation on the basis of this comparison.

Abstract
The present invention aims at being able to prevent unintentional operation and to improve operating characteristics even if the entirety of a touch panel can be effectively used as a touch operating surface. Specifically, a touch control table that is a table storing thresholds set in accordance with regions on the touch screen is provided, and this touch control table has “Region” and “Threshold” as respective columns. A CPU detects a contact position and area of contact as contact states at the time of touch operation on the screen (touch screen) of a touch input display unit. The CPU identifies the touched region on the basis of the contact position, and thereafter compares the detected area of contact to the threshold set in accordance with the region. The CPU interprets the touch operation on the basis of the comparisons of the region.

13. A method of controlling a touch operation in an information processing device, comprising:
-
detecting a contact position and an area of contact when there is a touch operation on a touch screen having a touch panel attached thereto; identifying a region on the touch screen that has been touched among a plurality of regions on the touch screen on the basis of the contact position that has been detected; and interpreting the touch operation on the basis of a comparison of the area of contact when the region on the touch screen is identified, said comparison being obtained when the detected area of contact is compared to a threshold set in accordance with said region.
