Step Detection Methods and Apparatus |
| 摘要 |
Step detection methods and apparatus are described. According to one aspect, a footstep detection method includes obtaining accelerometer data regarding movements of a user device, filtering the accelerometer data to remove frequencies above a typical stepping frequency range of a user, after the filtering, analyzing individual ones of a plurality of cycles of the accelerometer data to determine whether any of the individual cycles corresponds to a user taking a footstep with the user device, and as a result of the analyzing, indicating at least one of the individual cycles as corresponding to the user taking a footstep. |

1. A footstep detection method comprising:
obtaining accelerometer data regarding movements of a user device; filtering the accelerometer data to remove frequencies above a typical stepping frequency range of a user; after the filtering, analyzing individual ones of a plurality of cycles of the accelerometer data to determine whether any of the individual cycles corresponds to a user taking a footstep with the user device; and as a result of the analyzing, indicating at least one of the individual cycles as corresponding to the user taking a footstep. |
