Control device comprising detection unit configured to perform detection of brain wave and control method therefor

The present technology relates to a control device and a control method capable of providing a more convenient electroencephalogram input user interface.Provided is a control device including a detection unit configured to perform detection of a brain wave included in a measured biometric signal of a user and detection of a user action based on information other than the brain wave included in the biometric signal, and a processing unit configured to perform a predetermined process based on the brain wave in a case where the user action is a predetermined action. For example, the present technology can be applied to a measurement device capable of measuring a brain wave signal.
