iWatch likely contains pedometer; Jawbone designer imagines ‘wearable kit of sensors’
With Apple’s iWatch looking set to have a major health and fitness angle, and likely to be bristling with sensors, it seems likely that a pedometer will be one of them. Patently Apple reports on an Apple patent designed to allow steps to be accurately tracked using a wrist-mounted device. Or, in patentspeak:
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.
