An electronic watch includes a housing and a crown assembly including a rotatable actuation member. The rotatable actuation member includes a knob external to the housing and configured to receive a rotational input and a shaft assembly coupled to the knob and positioned at least partially within the housing, the shaft assembly defining a sensing surface configured to rotate in response to the rotational input. The electronic watch further includes an optical sensing system configured to detect the rotational input, the detecting including directing light onto the sensing surface, receiving reflected light from the sensing surface, and producing a signal corresponding to a rotational motion of the sensing surface, the signal based at least in part on an interference between the light directed onto the sensing surface and the reflected light.

Described herein is a wearable device, which comprises an ultrasonic system. The ultrasonic system comprises a substrate that comprises an ultrasonic transducer array and accompanying circuitry. The wearable device is configured to produce useful ultrasonic images.

A display device (100) for a watch (1000) including at least one light source (200) and including, between a dial (300) carrying at least one reference scale on a top side (301) and a crystal (400) on the side facing the user a set of hands (10) coaxial about an axis of rotation (D) including at least a first luminous indicator (1) including a first light guide (11) arranged to diffuse some of the light emitted by said at least one light source (200), wherein the first light guide (11) includes first coupling microstructures (110) which are arranged to allow light to enter the first light guide (11) and/or to allow light to exit the first light guide (11).

An electronic watch includes a first hand that is rotated by a first motor, and indicates a higher digit of numerical information or time information, a second hand that is rotated by a second motor, and indicates a lower digit of the numerical information or the time information, and a motor controller. The motor controller performs a numerical value indication mode for driving the first motor and the second motor simultaneously to indicate an increase or decrease in the numerical information, or time correction mode for driving the first motor and the second motor simultaneously to correct the time information, and in the numerical value indication mode or the time correction mode, controls a drive frequency of the first motor and a drive frequency of the second motor such that angular velocity of hand movement of the first hand is less than angular velocity of hand movement of the second hand.

The present disclosure generally relates to user interface for electronic devices, including wearable electronic devices, and device settings based on user identification.

First interaction data may be received and used to determine a beginning sleep time. Second interaction data may be received and used to determine an interrupted period during an expected sleep period. Third interaction data may be received and used to determine an end sleep time.

A watch can include a watch body and a band for securing the watch to the user. The watch body can detect an identification of the band or combination of band portions, which can serve as an input to initiate actions performed by the watch body. For example, a type, model, color, size, or other characteristic of a band can be determined and used to select a corresponding action performed by the watch body. Identification of the band can be performed by components of the watch body that also serve other purposes. The watch body can respond to the identification of a particular band by performing particular functions, such as changing an aspect of a user interface or altering settings of the watch body.

A watch display member includes: a first surface and a second surface that are different in inclination angles, wherein a first notation is displayed on the first surface, and a second notation is displayed on the second surface.

The present disclosure relates to arranging the orientation of a display on device based on motion of the device. In one embodiment, a method includes detecting motion data for the device. The motion data includes data associated with rotational movement of the device. The method includes analyzing, by a controller, the data associated with rotational movement of the device to determine an orientation for presenting a display of the device. The method may also include controlling the device to rotate the display to the determined orientation.
