Claim:
1. An information processing device, comprising: a touch screen having a touch panel attached thereto; a memory that stores a plurality of thresholds that are different from each other for detecting touch operations so as to provide for differing touch sensitivities in various regions on the touch screen; and a processor that defines a plurality of regions on the touch screen, and assigns said plurality of thresholds to the plurality of regions, respectively, in accordance with a content of an image displayed on the touch screen or an orientation of the touch screen, or both, so that touch sensitivities are mutually different among at least some of the plurality of regions, wherein the processor receives signals from the touch screen to detect a contact position and an area of contact when there is a touch operation on the touch screen, wherein the processor further identifies a region on the touch screen where the touch operation has occurred among said plurality of regions defined on the touch screen, on the basis of the detected contact position and compares the detected area of contact to one of said plurality of thresholds assigned to said identified region, the processor interpreting the touch operation on the basis of this comparison and controlling a process corresponding to the touch operation, wherein said plurality of regions defined on the touch screen includes an indicator display region that displays a command indicator; a screen edge region that is arranged on an edge of the touch screen; and a whole region that includes said indicator display region and said screen edge region as sub-regions therein, the threshold assigned to the whole region being smaller than the threshold assigned to the indicator display region, and the threshold assigned to the indicator display region being smaller than the threshold assigned to the screen edge region, wherein when the processor determines that the touch operation had occurred in the indicator display region, the processor executes a process corresponding to the command indicator if the area of contact of the touch operation is larger than the threshold assigned to the indicator display region, and if the area of contact of the touch operation is smaller than the threshold assigned to the indicator display region, the processor compares the area of the contact with the threshold assigned to the whole region, and executes a corresponding process if the area of the contact is greater than the threshold assigned to the whole region, wherein when the processor determines that the touch operation had occurred in the screen edge region, the processor compares the area of contact of the touch operation with the threshold assigned to the screen edge region, and if the area of contact is larger than the threshold assigned to the screen edge region, the processor determines that the touch operation is invalid, and if the area of contact is smaller than the threshold assigned to the screen edge region, the processor compares the area of the contact with the threshold assigned to the whole region, and executes a corresponding process if the area of the contact is greater than the threshold assigned to the whole region, and wherein the processor measures a contact time for each region on the touch screen when the processor identifies that a plurality of regions have been touched, wherein, when the processor identifies that a touch operation has straddled multiple regions among said plurality of regions defined by the processor, the processor interprets the touch operation by determining that said touch operation has contacted one of said multiple regions on the basis of the measured contact time for each of the multiple regions, and wherein, when the processor identifies that the touch operation has straddled the multiple regions among said plurality of regions defined by the processor, the processor interprets the touch operation by determining that said touch operation has contacted one of said multiple regions that had the longest contact time among the multiple regions.
