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. |
