Alternatively, the user may rotate the input device 1 by rubbing the input device 1 attached to the index finger F against a flat surface or by using an instrument other than the finger. Here, the index finger F is an example of a "predetermined part".

In addition, although the case where the input device 1 is attached to the index finger F of the right hand will be described below, this is just an example. The input device 1 may be attached to any of the fingers of the right hand and the fingers of the left hand.

FIG. 2A is a schematic diagram of the structure of the input device 1. Note that in the following description, the L axis and the R axis are assumed. The L axis and the R axis are common to all the figures illustrated in the following description. As illustrated in FIG. 2A, the length direction of the index finger F is taken as the L axis. Further, the direction toward the tip of the index finger F is defined as the +L direction, and the direction toward the end of the index finger F is defined as the -L direction. Further, the radial direction of the index finger F is assumed to be the R axis. The direction away from the central axis of the index finger F is the +R direction, and the direction toward the central axis of the index finger F is the -R direction.
