The present invention relates to a wearable smart appliance in the form of a wristwatch. The appliance is designed to track a user's vital signs and send real-time alerts to a paired electronic device for remote monitoring of the user. More specifically, the appliance tracks vital signs such as heart rate, and notifies a parent or guardian if the user is in danger. The appliance also includes a water sensor that activates an alert if the sensor is underwater for a certain length of time. A GPS sensor detects the current location of the user and is included in the real-time alerts during emergencies.

Provided are a control and apparatus for a wearable device, an electronic device, and a computer-readable storage medium. The wearable device has a first operation mode and a second operation mode. The first operation mode is a mode for running a first system and a second system. The second operation mode is a mode for running only the second system. The first operation mode has a higher power consumption than the second operation mode. The control method includes: obtaining user behavior data (102), determining a user behavior status based on the user behavior data (104), and switching, in response to detecting that the user behavior status is a sleep status, the wearable device from the first operation mode to the second operation mode (106).

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.

A photoelectric converter including a crystalline silicon substrate having a light receiving surface including a smooth section and a rough surface section having surface roughness greater than the surface roughness of the smooth section and a light transmissive inorganic film so provided as to overlap with the smooth section and the rough surface section, and the film thickness t1 of a portion of the inorganic film that is the portion where the inorganic film overlaps with the rough surface section is smaller than the film thickness t2 of a portion of the inorganic film that is the portion where the inorganic film overlaps with the smooth section. The arithmetic average roughness of the rough surface section is preferably greater than or equal to 0.1 μm.

An electronic device such as a wearable device may have an optical sensor. The optical sensor may have a light source such as one or more visible-light light-emitting diodes or other light-emitting devices and may have a light detector formed from one or more photodetectors. The wearable device may have a wearable housing in which the optical sensor is mounted. During operation, light from the light source may pass through a transparent portion of the housing, may reflect from an external object such as a wrist or other body part of a user, and may be received by the photodetectors after passing through light control members. The light control members may be arranged in a ring with a center and may have curved shapes with concave surfaces that face the center. Each light control member may be formed from a stack of laminated bent light control films.

A user-wearable device comprises a device band and a housing section connected to the device band. The housing section comprises a roller and an extendable display spooled around the roller. The extendable display comprises a first end that is attached to the roller. The user-wearable device also comprises an anchor that is attached to a second end of the extendable display and that is located outside the housing section. The user-wearable device comprises a locking mechanism attached to the anchor. Separating the anchor from the housing section causes the extendable display to unspool from the roller and extend out of the housing section.

An electronic device includes a non-rectangular display, an information acquisition sensor, and a processor. The processor allocates information acquired from the information acquisition sensor to any of a plurality of display regions having different sizes or shapes within a display range. The information is displayed on the display in a different display mode depending on whether the information is allocated to a first display region or to a separate display region out of the plurality of display regions.

An information processing apparatus according to the present disclosure includes a fingerprint information acquisition unit that acquires fingerprint information, a determination unit that determines an action of a finger on the basis of the fingerprint information, and a processing unit that performs specified processing predetermined depending on the action on the basis of the determined action. This configuration makes it possible to perform a desired operation depending on the operation even with a compact apparatus, thereby enhancing user convenience.

A wearable device (100) includes a body (1) and a detection electrode (21). The body (1) includes an electrocardiosignal collection circuit (11), and an inner electrode (12) and an outer electrode (13) that are electrically connected to the electrocardiosignal collection circuit (11). The inner electrode (12) is configured to collect an electric potential signal of a first wearing position (200), and the outer electrode (13) is configured to collect an electric potential signal of a non-wearing position (300). The detection electrode (21) can move relative to the body (1), and the detection electrode (21) is configured to electrically connect to the electrocardiosignal collection circuit (11) and collect an electric potential signal of a second wearing position (400). The non-wearing position (300) and the second wearing position (400) are different from the first wearing position (200). The wearable device (100) can measure electrocardiosignal data in time.
