Abstract

Various systems and methods for tracking heart rate for music selection are described herein. A system to track heart rate for music selection comprises a target heart rate module to identify a target heart rate of a user for an activity session; a heart rate monitor module to receive a current heart rate of the user from a sensor coupled to the system; and an audio selection module to determine when a difference between the current heart rate and the target heart rate is larger than a threshold value, and when the difference is larger than the threshold value: identify a beats per minute of a current audio selection; determine a beats per minute to adjust the heart rate of the user from the current heart rate toward the target heart rate; and select a next audio selection from an audio library with a beats per minute similar to the beats per minute to adjust the heart rate.

31. The machine-readable medium of claim 26, wherein instructions to identify the beats per minute of the current audio selection comprise instructions to perform acoustic analysis of the audio selection.

32. The machine-readable medium of claim 26, wherein instructions to determine the beats per minute to adjust the heart rate of the user from the current heart rate toward the target heart rate comprise instructions to use a feedback controller to calculate the beats per minute.

33. The machine-readable medium of claim 32, wherein the feedback controller comprises a proportional integral derivative (PID) controller.

34. The machine-readable medium of claim 33, wherein the PID controller includes a plurality of coefficients.

35. The machine-readable medium of claim 26, wherein instructions to select the next audio selection from the audio library comprise instructions to:

identify a potential next audio selection from the audio library;

analyze the potential next audio selection to determine whether the beats per minute of the potential next audio selection substantially matches the beats per minute to adjust the heart rate; and

when the beats per minute of the potential next audio selection substantially matches the beats per minute to adjust the heart rate, select the potential next audio selection from the audio library as the next audio selection.

36. The machine-readable medium of claim 35, wherein instructions to analyze the potential next audio selection comprise instructions to perform acoustic analysis of the potential next audio selection.

37. The machine-readable medium of claim 35, wherein the instructions to select the next audio selection are performed during playback of the current audio selection.

38. The machine-readable medium of claim 35, further comprising instructions to:

store a history of audio selections played to the user; and

when the potential next selection is in the history of audio selections, select a different potential next selection to analyze beats per minute.

39. The machine-readable medium of claim 26, further comprising instructions to:

present a notification to the user when the difference between the current heart rate and the target heart rate is larger than the threshold value.

40. The machine-readable medium of claim 39, further comprising instructions to:

when a timeout period expires after the notification is presented to the user, evaluate the difference between the current heart rate and the target heart rate to determine whether it has been larger than the threshold value for the timeout period, and is so, performing the identifying the beats per minute of the current audio selection, determining the beats per minute to adjust the heart rate of the user from the current heart rate toward the target heart rate, and selecting the next audio selection from the audio library.

41. A system to track heart rate for music selection, the system comprising:
