ABSTRACT:
In a pointing system for use in notifying an operator of a cursor position on a display without relying on a sense of sight, information is derived in relation to an interactive item from a plurality of positions which are adjacent to the cursor position. A tactile sense or an inner force sense is determined by a relationship of the interactive items between the cursor position and the adjacent positions. The tactile sense may be displayed by a tactile display while the inner force sense, by a movable stage controllable by braking units. An absolute coordinate system may be used to indicate a position of the tactile display or the movable stage and is in one-to-one correspondence to a coordinate system of the display.
