Abstract: A technique and a light emitting device that can smoothly read out data while tracking a position of the light emitting device (an object). The light emitting device expresses data with “a change in the change of a color (switching of changes)”. The light emitting device specifies an object and the position thereof with a first primary change and thereafter expresses data with, so to speak, a secondary change (switching of the primary change). The primary change means that G and B alternately turn on (indicated by G*B) and so on. The secondary change means a change from the condition (G*B), in which G and B alternately turn on, to the condition (B*R) in which B and R alternately turn on. Thus, since data is expressed by the change of color condition changes, it is easier to freely express data while the position of an object is specified.
