A contribution degree calculation apparatus calculates a contribution degree of each of a plurality of players in a video game in which the plurality of players participate. The contribution degree calculation apparatus includes: a biological information obtainer configured to obtain biological information respectively corresponding to the plurality of players; a game data obtainer configured to obtain game data generated by the plurality of players playing the video game; a first calculator configured to calculate a first index related to a degree of an influence by one of the plurality of players to another player and a second index related to a mental load of the one player, from biological information corresponding to the one player; and a second calculator configured to calculate a contribution degree of the one player from the first index and the second index and from the game data.

A bio-information detecting apparatus includes: a band member curved in a C-shape, and attached around a neck part of an examinee from a back side of the neck part; and a pair of electrodes for cardiac potential measurement disposed at positions on the band member that come into contact with right and left skin surfaces of the neck part, and in the pair of electrodes, a position of the electrode on the right is located relatively more frontward than a position of the electrode on the left. The bio-information detecting apparatus further includes a substrate to optically measure a blood oxygen saturation for pulse measurement at a position on the band member that comes into contact with the neck part of the examinee, and a pressing force of the substrate against the skin surface of the neck part is 0.96 to 1.21 [N/cm].

In a sleep quality estimation device, a respiration sensor detects the respiratory waveform of a subject. A sleep stage estimation unit estimates the sleep stage of the subject during sleep based on the respiratory waveform detected by the respiration sensor. In a sleep rhythm model database, models associated with the appearance probability of &#x3b4;-wave for the sleep stage during sleep are recorded. A sleep quality estimation unit estimates the appearance time of &#x3b4;-wave of the subject during sleep based on the sleep stage of the subject estimated by the sleep stage estimation unit and the models associated with the appearance probability of &#x3b4;-wave for the sleep stage recorded in the sleep rhythm model database, and estimates the sleep quality of the subject based on the appearance time of &#x3b4;-wave.

A heartbeat sensor obtains a heartbeat of a driver. A concentration level computing unit estimates a concentration level of the driver at a time later than a timing of obtaining the heartbeat by the heartbeat sensor, on the basis of the heartbeat obtained by the heartbeat sensor. A state determining unit controls driving assistance for a vehicle on the basis of a comparison of the concentration level of the driver estimated by the concentration level computing unit with a target concentration level of the driver that is set in association with a position or an environment in which the vehicle driven by the driver is predicted to travel.
