Abstract: A state prediction system includes a controller. The controller is configured to acquire a current state value indicating a current state of a targeted individual in a group. The controller is configured to acquire a state propagation amount indicating a state amount propagated from another person in the group to the targeted individual by communication between the targeted individual and the other person. The controller is configured to predict a future state value indicating a future state of the targeted individual from the acquired current state value of the targeted individual and the acquired state propagation amount.

Abstract: 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.

Abstract: A judgment ability calculation apparatus calculates a judgment ability of a player of a video game. The judgment ability calculation apparatus includes: a biological information obtainer configured to obtain biological information relating to the player in linkage with time information; a first calculator configured to calculate a time change in an internal state of the player on the basis of the biological information; an extractor configured to extract an event of attention in linkage with time information; and a second calculator configured to extract an internal state of a predetermined period including a timing at which the event of attention occurs from the time change in the internal state on the basis of the time information linked with the event of attention, the second calculator being configured to calculate the judgment ability of the player from the extracted internal state.

Abstract: In a system, a motion estimating unit is configured to output supervising reference position values of the plurality of regions of the body of a person or the like at a correct answer reference time at which a time difference from a measurement time is the same as a time difference between the reference time and the estimation time based on learning sensor-measured values over the first time length before the measurement time of the learning sensor-measured values using the learning sensor-measured values measured while the person or the like is performing a predetermined motion by learning according to an algorithm of a machine learning model and the supervising reference position values of the plurality of regions of a person or the like at the time of measurement thereof.

Abstract: Methods, systems, and apparatus for a drowsiness detection system that alerts the user to potentially drowsiness. The drowsiness detection system includes a sensor configured to detect a heart rate of a user. The drowsiness detection system includes an indicator configured to alert the user before the user becomes drowsy and a processor that is connected to the sensor and the indicator. The processor is configured to obtain the heart rate of the user and measure the heart rate of the user. The processor is configured to calculate at least one of a heart rate variability or a heart rate interval of the user based on the measured heart rate. The processor is configured to determine that the at least one of the heart rate variability or the heart rate interval of the user indicates that the user is becoming drowsy and activate the indicator to alert the user before the user becomes drowsy.
