PROBLEM TO BE SOLVED: To reduce disturbance components included in a detection signal of a biosensor without using an acceleration sensor and to highly accurately perform a determination using the biological information irrelevant to a type of an operation device and without causing a cost increase.SOLUTION: A signal processing section 12 of a signal processing unit 200 detects an operation period on the basis of operation information outputted from an operation information acquisition section 11, determines an operation content, and reads a template waveform information corresponding to the determined operation content from an operation information DB 13. According to the read template waveform information, a signal waveform processing process such as a subtraction process and an invalidation process for suppressing disturbance components is performed on signals in a section included in the detected operation period and in a fixed period before and after the operation period among pulse wave signals after a preprocessing. |
