Patent ID: 8307130

Claim:
A control system, comprising: an information processing apparatus; and an external device communicably connected with the information processing apparatus; the information processing apparatus including: an execution unit for executing an application, a threshold value setting unit for setting a first threshold value for the information processing apparatus and a second threshold value for the external device which are determined according to the running application, a first detection unit for detecting a use state of the information processing apparatus, and a first transmission and reception unit for exchanging information with the external device; and the external device including: a second transmission and reception unit for exchanging information with the information processing apparatus, a second detection unit for detecting an input signal to the external device, a determination unit for determining whether or not to change the operational state of the external device based on the first and second threshold values set by the threshold value setting unit of the information processing apparatus and based on the detection result by at least one of the first detection unit or the second detection unit, and a change processing unit for changing the operational state of the external device based on the determination result by the determination unit.
