Abstract: An awakening support system includes: a lyric presence determination unit configured to determine whether lyrics are contained in a target reproduction sound that is being output from an audio device in a mobile body; and an awakening effect control unit configured to, when it is determined by the lyric presence determination unit that lyrics are contained in the target reproduction sound, execute at least one selected from: first bass amplification processing that amplifies and outputs a prescribed bass part of the target reproduction sound from the audio device; cool air sending processing that sends out cool air from an air conditioning device provided in the mobile body; and illuminance increasing processing that increases illuminance of a lighting device provided in the mobile body.

Abstract: An embodiment provides a state estimation device including: an acquisition unit configured to acquire a state variable including an observation value obtained by observing a steersman who steers an moving object; and an estimation unit including a state model having a correlation between the state variable and a cognitive load during steering of the steersman and configured to estimate a state of the steersman from the state variable acquired by the acquisition unit.

Abstract: A biological state guidance device includes a biological state estimation unit configured to estimate a biological state of an occupant of a vehicle, a target value decision unit configured to decide on a target value that is an index for setting the biological state of the occupant as a target state, a stimulus generation unit configured to control a stimulus generation device for generating a stimulus for guidance so that the biological state of the occupant is close to a target value on the basis of the estimated biological state and the target value, and a position information detection unit configured to detect position information of the vehicle. The target value decision unit decides on the target value on the basis of the position information.

Abstract: A biological state guidance device includes a biological state estimation unit configured to estimate a biological state of a driver, a target value decision unit configured to decide on a target value of the biological state, an audio stimulus generation unit configured to generate an audio stimulus for guidance so that the biological state is close to a target value, a fellow passenger information acquisition unit configured to acquire fellow passenger information, a target state decision unit configured to decide on a target state of a biological state of the fellow passenger, and a vibration stimulus generation unit configured to control a vibration stimulus generation device for stimulating the fellow passenger by vibrations. The vibration stimulus generation unit generates the vibrations for guiding the fellow passenger to have the target state as the biological state.
