1. A device comprising:
a case body;
a plurality of markers configured to emit light to an outside of the case body, where the plurality of markers are disposed at respective positions over the case body such that the light operates to provide information on a position of the device;
a control portion configured to light the plurality of markers at predetermined intervals of time such that the position of the device is determined during such predetermined intervals of time;
an indicator configured to emit visible light to a user to indicate a state of the device, where presence of the visible light from the indicator during the predetermined intervals would interfere with the light from the plurality of markers and interfere with the determination of the position of the device during the predetermined intervals, wherein:
a light source for the indicator is separately controllable from a light source for the plurality of markers, and
the control portion lights the indicator in a period during which the plurality of markers are unlit such that the visible light from the indicator does not interfere with the determination of the position of the device during the predetermined intervals.
