Sound-output-control device, sound-output-control method, and sound-output-control program

A mobile information processing apparatus comprising:

• a processor configured to output an audio signal,
• wherein the processor is configured to change an original tempo of the audio signal to a current tempo based on a comparison between a heart rate of a user detected by a sensor and a target heart rate range,
• wherein the processor is configured to determine the target heart rate range based on at least an exercise intensity specified by the user and an anaerobic threshold of the user, the target heart rate range thereby being a user-defined target heart rate range,
• wherein the anaerobic threshold is determined from a slope or stability of the user's heart rate with a varied exercise load or intensity, and
• wherein the processor is configured to change the current tempo of the audio signal according to a change of the comparison to lead the heart rate of the user to the user-defined target heart rate range,
• wherein the processor is configured to change the current tempo by selecting a track from a database of tracks and associated tempos based on a target tempo, and the processor is configured to output the audio signal to play the selected track,
• wherein the mobile information processing apparatus is configured to be worn on an arm of the user,
• wherein the processor is configured to estimate the anaerobic threshold at least in part by gradually increasing varying a tempo of the audio signal while the heart rate is detected.
