1. A watch comprising:
- a display located on a first surface of the watch;
one or more optical sensors located on a second surface, opposite the first surface, of the device and configured to detect a reflection of ambient light, from a source external to the watch, that has passed through a user; and
logic coupled to the one or more optical sensors, the logic configured to;
generate one or more signals based on the detected reflection of ambient light, andchange an operating state of the display based on the one or more signals.

Abstract
A portable electronic device including one or more sensors for detecting ambient light through the user'"'"'s skin is disclosed. The sensors can be optical sensors such as ambient light sensors (ALS) and/or cameras. Examples of the present disclosure include a device that can determine the intensity of ambient light and can change the operating state of the portable electronic device based on the ambient light environment. The device can also determine the type of ambient light and generate notifications to the user based on the determined type.

12. A method for adjusting one or more properties of a display included in a watch, the watch including one or more optical sensors, the method comprising:
-
detecting a reflection of ambient light, from a source external to the watch, that has passed through a user using the one or more optical sensors, wherein the one or more optical sensors are located on a second surface of the watch; generating one or more signals based on the detected reflection of ambient light; and changing an operating state of the display based on the one or more signals, wherein the display is located on a first surface, opposite the second surface, of the watch. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
