Abstract
A cursor can be operated continuously from a picture now being displayed to another picture not yet displayed. Further, an icon area arranged in another picture not yet displayed can be pointed out accurately without depending upon the operational characteristics of operators. When depressed by an operator, a pad-type input section (5) detects the two-dimensional position and the magnitude of the depression force at a pressure point. The detected data are applied to an encode section (14) through a signal amplifier (13). The encode section (14) detects the two-dimensional coordinates and the pressure value at the pressure point. On the other hand, a domain registering section (15) registers respective partitions on each of a plurality of pictures (8) as a domain group (11) of three-dimensional position domains. Therefore, when the output of the encode section (14) is compared by a comparing section (17) with respect to the positional data, if both match, the data detected by the pad-type input section (5) are assigned to a representative position (12) in a picture of the domain group (11), so that it is possible to accurately allow an input applied onto the pad-type input section (5) to correspond to a two-dimensional area of each of a plurality of pictures (8).
