Device control apparatus and a device control method

A device control apparatus for controlling the apparatus for vehicle based on the user of the biological signal, the biological signal measurement section for measuring a time series biological signal of the user (101), the biological signal measurement section (101) from a biological signal of a time series which is measured by the parameter extraction unit for extracting a parameter value of the time series for evaluating the state of the user (102), using the parameter values ​​extracted by the parameter extraction unit, wherein responsible for the altered biological signal, whether it is due to a change in the physical condition of the user, the determination unit whether the due changes in the surrounding environment temperature of the user (120), the determination unit (120) based on the determination result in, and a control unit for controlling the apparatus for vehicle (130).
