Abstract
A wearable device includes: a first sensor configured to provide a first sensor signal; a second sensor configured to provide a second sensor signal; and a processor configured to i) determine whether the wearable device is being worn based on the first sensor signal, and ii) calibrate the second sensor responsive to determining that the wearable device is being worn. Also, a holdable device includes a first sensor configured to provide a first sensor signal; a second sensor configured to provide a second sensor signal; and a processor configured to i) determine whether the holdable device is being held based on the first sensor signal, and ii) calibrate the second sensor responsive to determining that the holdable device is being held.
