Abstract
A control system includes an information processing apparatus and a terminal device which perform wireless communication with each other, wherein the terminal device is moved with a user, and includes: a switching request signal transmission section that transmits a switching request signal, the information processing apparatus includes: a received signal strength measuring section that measures a received signal strength of a transmitted signal; and a control section that sets the received signal strength measured when receiving the switching request signal to a switching threshold value, and switches the information processing apparatus from the second status to the first status when the received signal strength becomes less than the switching threshold value, and switches it from the first status to the second status when the received signal strength becomes larger than the switching threshold value.
