Abstract
A projector and a mobile terminal are connected wirelessly in two-way communication, and thus the projector is controlled by the mobile terminal. Also, projection data is exchanged between the mobile terminal and the projector, or between a data server connected to a network and the projector using a command of the mobile terminal. Furthermore, when a plurality of mobile terminals send projection data simultaneously, a communication enabled state is established with only one mobile terminal by a predetermined procedure, or one projector's projection screen is divided in order to project a plurality of projection data simultaneously.
