Abstract: In some implementations, optimizations for detecting steps when a pedometer is worn at a user's wrist are described. In some implementations, a threshold crossing step detection method can be enhanced for wrist locations by counting the number of positive peaks between comparison threshold crossings, adjusting a minimum peak-to-peak threshold for qualifying threshold crossings, and inferring a second step based on the amount of time between threshold crossings. In some implementations, the pedometer can automatically determine that the pedometer is being worn on a user's wrist.

Abstract: Techniques are provided for improving pedometer readings. In some embodiments, motion data, such as acceleration data is detected, and a magnitude of the acceleration data, referred to as the modulus, is processed for improved step detection. Techniques involve computing a moving average of the modulus and applying an acceleration threshold filter to the modulus. Crossings are detected based on peak-to-peak swing of the modulus about the moving average. In some embodiments, the frequency of the modulus is used in an adaptive filtering technique. based on the dominant frequency of the modulus, a frequency band is selected to filter to modulus. The frequency band may be dynamically changed to one of several frequency bands when a significant frequency change is detected in the dominant frequency of the modulus. In some embodiments, steps are detected based on the acceleration threshold-filtered and the frequency-filtered modulus.
