摘要:
An information selecting apparatus includes a computer, and makes a user select an arbitrary item from a plurality of items by a direction input of the user. Each of the items is assigned to a direction based on an input frequency, for example. In a case that a direction input is performed by means of a polygonal guide, the items are assigned to directions corresponding to the vertexes of the guide and directions corresponding to the parts except for the vertexes. For example, a high-frequency item is assigned to the direction corresponding to the vertex, or a range of the direction assigned to the high-frequency item is relatively made larger. Furthermore, when a direction corresponding to the vertex is input, items assigned to the parts except for the vertexes may temporarily be assigned to other vertexes. In addition, when predetermined operation data is input, the items of the directions corresponding to the vertexes and the items of the directions corresponding to the parts except for the vertexes may be interchanged.
