Abstract

A method for controlling an audio output comprises playing a first audio file having a first tempo, measuring a first heart rate of a user, determining whether the first heart rate of the user is greater than a target heart rate, and playing a second audio file having a second tempo, the second tempo is slower than the first tempo, responsive to determining that the first heart rate of the user is greater than the target heart rate.

First claim

What is claimed is:

1. A method for controlling an audio output, the method comprising:
receiving a target heart rate for a user;
calculating a warmup heart rate for the user based at least in part on the target heart rate;
starting a warmup timer;
playing a first audio file having a first tempo, wherein the first tempo corresponds to the warmup heart rate, wherein the first audio file includes music having the first tempo;
determining whether the warmup timer has expired;
responsive to determining that the warmup timer has not expired,
measuring a first heart rate of the user,
determining whether the first heart rate of the user is greater than the warmup heart rate, and
responsive to determining that the first heart rate of the user is greater than the warmup heart rate, playing a second audio file having a second tempo, the second tempo being slower than the first tempo; and

responsive to determining that the warmup timer has expired,
playing a third audio file having a third tempo, wherein the third tempo corresponds to the target heart rate,
measuring a second heart rate of a user,
determining whether the second heart rate of the user is greater than the target heart rate,
determining a time remaining in the third audio file,
responsive to determining that the second heart rate of the user is greater than the target heart rate, playing a fourth audio file having a fourth tempo, the fourth tempo being slower than the third tempo,
responsive to the time remaining in the third audio file being greater than a threshold, completing the playing the third audio file before playing the fourth audio file;
determining whether an acceleration of the user is below an acceleration threshold,
responsive to determining that the acceleration of the user is below the acceleration threshold, pausing the playing the third audio file or pausing the playing the fourth audio file, and
playing a fifth audio file having a fifth tempo, the fifth tempo being faster than the third tempo, responsive to determining that the second heart rate of the user is not greater than the target heart rate.
