Electronic device, recording medium and method
First Claim
1. An electronic device, comprising:
- a screen display unit that has a screen, displays operation information on a user'"'"'s operations in at least one effective area within the screen, and distinguishes the at least one effective area from at least one ineffective area within the screen;
a touch input unit that accepts the user'"'"'s tactile touch operation upon a screen of the screen display unit;
a touch location detection unit that detects the touch location of the touch operation within the screen, upon acceptance of a touch operation through the touch input unit; and
a display mode change unit that changes a relative relation between the display mode of the at least one effective area and the display mode of the at least one ineffective area within the screen, if the touch location detected by the touch location detection unit is determined to be corresponding to the at least one ineffective area within the screen.

Abstract
Methods, computer program products, computing and printing systems for improved screen display and touch input, where an operation/display unit comprises a screen display unit such as a LCD; a touch location detection unit, which is a touch panel that accepts a user'"'"'s touch operation; a touch decision unit that determines the touch location of the user'"'"'s touch operation to the touch panel; and a touch execution unit that executes functions according to the user'"'"'s touch location. If the user'"'"'s touch location is within the effective area(s) of the operation button(s), then the touch execution unit executes the function allocated to the operation button(s). If the touch location is outside of the effective area(s) of the operation button(s), then the region outside of the operation button(s) is displayed as grayed-out.
