First Claim
1. A device comprising:
- a touch panel including a touch screen located on a first surface of the device;
one or more electrodes located on a second surface of the device, the second surface opposite the first surface;
sensing circuitry coupled to the one or more electrodes and configured to generate sense signals indicative of one or more distances between the one or more electrodes and a proximate object; and
logic coupled to the one or more electrodes, the logic calculates the one or more distances.

Abstract
A portable electronic device include one or more electrodes for calculating distances and rotational angles between the device and the user is disclosed. Based on the calculated distances and rotational angles, a physical activity of the user can be determined. Additionally, the calculated distances and rotational angles can be used for compensation of optical artifacts in one or more signals detected by the device. User movement or physical activity can introduce optical artifacts, which can lead to erroneous determination of the one or more characteristics. The calculated distances and rotational angles can be used to reduce or remove the optical artifacts, leading to a more accurate determination of the one or more characteristics of the user.
