摘要:
An object information providing apparatus and an object awareness apparatus are provided. The object information providing apparatus includes at least one light emitting element and controls a light emitting state of the at least one light emitting element so as to provide information of an object to the object awareness apparatus in the form of light. Accordingly, the object information providing apparatus provides information of a diverse number of different objects and the object awareness apparatus recognizes the information of the different objects such that the object awareness apparatus becomes aware of the identity and the location of the different objects.
