Abstract

A mobile terminal device includes a display section, a touch panel for detecting a touch operation at least on a display area of the display section, a judgment section for judging whether or not a contact area of the touch operation is equal to or larger than a predetermined threshold value when the touch operation on an outer side region which is the outer peripheral portion of the touch panel is detected, and a control section for disabling the touch operation on the outer side region when judged that the contact area of the touch operation on the outer side region is equal to or larger than the predetermined threshold value. Accordingly, an erroneous operation is prevented during a normal touch operation without requiring a specific operation.

Claims

1-6. -6. (canceled)

7. A mobile terminal device comprising:

a display section;

a touch panel for detecting a touch operation at least on a display area of the display section;

a judgment section for judging whether or not a contact area of the touch operation is equal to or larger than a predetermined threshold value when the touch operation on an outer side region which is an outer peripheral portion of the touch panel is detected; and

a control section for disabling the touch operation on the outer side region when judged that the contact area of the touch operation on the outer side region is equal to or larger than the predetermined threshold value.

9. The mobile terminal device according to claim 7, further comprising a posture detection section for detecting a posture of the device,

wherein, when the device can be assumed to be used in a portrait orientation, by the posture detection section, the control section limits a range of detecting the touch operation to a predetermined region including a lower end out of the outer side region.

10. The mobile terminal device according to claim 9, wherein, when the device can be assumed to be used in a landscape orientation by the posture detection section, the control section limits the range of detecting the touch operation to a region including a lower right corner and a lower left corner, out of the outer side region.

11. A mobile terminal device method for preventing operational errors, comprising:

a detecting step of detecting a touch operation, by a touch panel for detecting the touch operation at least on a display area of a display section, on an outer side region which is an outer peripheral portion of the touch panel;

a judging step of judging whether or not a contact area of the touch operation on the outer side region is equal to or larger than a predetermined threshold value; and

a disabling step of disabling the touch operation on the outer side region when judged that the contact area of the touch operation on the outer side region is equal to or larger than the predetermined threshold value.

12. A non-transitory computer-readable storage medium having a program stored thereon that is executable by a computer of a mobile terminal device equipped with a display section and a touch panel for detecting a touch operation at least on a display area of the display section, the program comprising:

a touch operation detecting function of detecting the touch operation on an outer side region which is on an outer peripheral portion of the touch panel;

a judgment function of judging whether or not a contact area of the touch operation on the outer side region is equal to or larger than a predetermined threshold value; and

a touch operation control function of disabling the touch operation on the outer side region when judged that the contact area of the touch operation on the outer side region is equal to or larger than the predetermined threshold value.
