FACILITATING OPERATION OF CONTROLS DISPLAYED IN A DISPLAY SURFACE INDEPENDENTLY OF THE SIZE OF THE DISPLAY SURFACE

摘要

A method, computer program product and system for facilitating operation of controls displayed in a display surface independently of the size of the display surface. The system includes a touchscreen which displays a screen on the display surface and which inputs an operation point operated by a user on the display surface, and a conversion unit that defines a point which is in a predetermined positional relationship with an operation point operated by the user on the touchscreen as an operation point to be operated. In response to input of an operation on an edge of the display surface, the conversion unit may define as the operation point to be operated a point that is positioned in a center area of the display surface except its edges and that is in a predetermined positional relationship with the operation point at which the edge of the display surface was operated.
