A watch having a cover is described. An optical sensor subsystem is attached adjacent to or directly on an interior surface of the cover. In some cases, the optical sensor subsystem includes a substrate to which a light emitter and a light receiver are attached. The light receiver is configured to receive light emitted by the light emitter and reflected from the skin of a person that wears the watch. In some cases, the light emitter and light receiver are separated by a light-blocking wall that abuts the interior surface of the cover. In some cases, a light filter is attached adjacent or directly on the interior surface of the cover, between the cover and the light receiver.

An electronic timepiece includes a storage that stores specific-region DST application rule information and local time information that includes, in association with each other, DST application rules for each region and standard-wave transmitting station information indicating each station transmitting standard waves receivable in the region; a processor that controls clock time to be kept by a clock circuit and displays time to be displayed on a display; and a standard wave receiver that receives standard waves and obtains time information. The processor calibrates the clock time based on the time information indicated by the standard waves received by the standard wave receiver, and controls the display time based on whether the specific-region DST application rule information and the DST application rule information associated with the standard-wave transmitting station information indicating a station transmitting the received standard waves satisfy a predetermined condition.

A portable electronic timepiece includes a display unit which displays an image, and a processor which is operative to display, on the display unit, route information on a traveling route of a user, switch a scale of the route information displayed on the display unit, and in a case where a given point set in association with the route information of a predetermined scale cannot be displayed within a display range of the display unit, change a display mode of the display unit to a display mode that is different from the display mode of displaying the route information.

A wearable electronic device includes a housing and a band attached to the housing. The band has an indicator with a variably and/or progressively illuminable portion. The indicator of the band conveys to a user an analog representation of the completion progress of an activity or task tracked by wearable electronic device. The wearable electronic device also includes a processing unit within the housing, and a sensor operatively coupled to the processing unit. In some cases, the sensor is a motion sensor such as an accelerometer or a gyroscope. In other examples, the sensor is a health sensor or a biometric sensor. Sensor data is used to update the indicator.

According to one embodiment of the preset specification, a method for controlling a wearable device for displaying visual information on a first display area and on a second display area can comprises the steps of: detecting that the wearable device has been changed to a charging state; displaying first visual information on a first display area; displaying second visual information on a second display area; detecting an event relating to a first application while the wearable device is in a charging state; and displaying, on the second display area, third visual information relating to the first application. At this time, the first visual information of the first display area can be displayed on a display unit of the wearable device, and the second visual information of the second display area can be displayed on the basis of a light source projected outside of the wearable device.

The present disclosure generally relates to context-specific user interfaces.

A user interface is provided to schedule a sleep schedule associated with an alarm. Various user interface elements may be presented using the user interface. Responsive to user selection of these user interface elements, certain actions may be performed to configure aspects of the sleep schedule.

One embodiment provides a method, including: monitoring, using an accelerometer integrated with an information handling device, gravitational acceleration experienced by the information handling device; identifying, based on the monitoring, a change in the gravitational acceleration from a first gravitational acceleration metric to a second gravitational acceleration metric; and adjusting, responsive to the identifying, a time-keeping standard referenced by the information handling device based on the second gravitational acceleration metric. Other aspects are described and claimed.

The present disclosure generally relates to methods and user interfaces for providing clock user interfaces. In some embodiments, methods and user interfaces for providing clock user interfaces displaying simulated emitted light, methods and user interfaces for displaying clock user interfaces including astronomical object, methods and user interfaces for displaying clock user interfaces that include adjustable time indications, methods and user interfaces for displaying clock user interfaces that include multiple calendar systems, methods and user interfaces for displaying clock user interfaces including animated numerals, methods and user interfaces for displaying clock user interfaces with colors that are based on a selected color, and/or methods and user interfaces for displaying clock user interfaces including animated lines are described.
