PROBLEM TO BE SOLVED: To solve the problems that a user hardly instructs an object the user wants to instruct because display is increasingly fined in a user interface using a touch panel and that an object the user wants to instruct is sometimes hidden by a finger.SOLUTION: Positions inputted to an input surface are detected to generate input coordinates, the input coordinates are stored in a time series order, instruction item directions of instruction items are calculated from the input coordinates in a time series order, instruction item positions where the instruction items should be displayed are calculated from the input coordinates and the instruction items, and the instruction items are combined on a display surface at the instruction item position on the screen. When an input is started, control is performed so as to change the positions of the instruction items in accordance with input coordinates, and further, when an input locus satisfies a prescribed condition, control is performed so as to also change the directions of the instruction items according to the input locus, then, the coordinates of input points of the instruction items are defined as determined coordinates when the input is finished, and processing corresponding to the coordinates is performed.SELECTED DRAWING: Figure 1 |
