<p><P>PROBLEM TO BE SOLVED: To provide a technique capable of improving precision in the designation operation of coordinate positions of a pointer, or the like with a simple structure and capable of allowing a user to perform operation more intuitively. <P>SOLUTION: A touch sensor 20 is in a three-dimensional shape and is nearly circular in a top view. A convex section 25 is formed by a curved surface at the center. In the convex section 25, an inner curved surface section 31 that is a convex curved surface is formed at a center 30 in the center, the height becomes lower concentrically toward the outside once, and a bottom section 32 is formed at the deepest section. Then, from the bottom section 32, the height gradually becomes higher concentrically, and an outer curved surface section 33 that is a curved surface is formed up to an edge section 34. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
