eCompass for high-precision pedestrian dead reckoning
Fitness-tracking smartphone apps, smartwatches, and bands need continuous location data for mapping and recording, and accuracy is critical for wearers who like to monitor their progress and share achievements online. A built-in eCompass helps calculate location when satellite signals are unavailable, such as inside buildings or when running or cycling under tree cover. A new eCompass reduces the heading error to less than 4° instead of the typical 10° of current devices.
