A portable electronic device configured to be positioned on a users wrist, the portable device being configured to perform an electrocardiogram, ECG, the portable electronic device includes a watchcase, a case back, configured to be at least partially in contact with the skin of the wrist, a glass, a bezel, mounted on the watchcase and surrounding the glass, movable in rotation with respect to the watchcase, a first ECG electrode, made of conductive material, on the case back and configured to be in contact with the skin of the wrist, a second ECG electrode, made of conductive material, on the bezel, an ECG electronic module, electrically connected to the first ECG electrode and the second ECG electrode, and configured to receive and process electrical signals from a user and retrieved by the ECG electrodes, to perform an electrocardiogram.

A modular sensing assembly may be used to detect user inputs at an electronic device. Example user inputs include touch inputs, fingerprint inputs, translational inputs, audio inputs, biometric inputs, and the like. Inputs received using the modular sensing assembly may be used to control a graphical output of a display of the electronic device. A modular sensing assembly may be configured, for example, as a power button, a key of a keyboard, a control button (e.g., volume control), a home button, a watch crown, and so on.

An information processing device includes at least one processor, in which the at least one processor acquires first information related to a first movement state of at least one of an arm and a leg of a user performing a movement, the first movement state on which a movement state of a torso of the user is superimposed, acquires second information related to a second movement state of the torso of the user performing the movement, and generates third information related to a third movement state of the at least one of the arm and the leg of the user based on the first information and the second information.

A processor-based personal electronic device (such as a smartphone) is programmed to automatically respond to data sent by various sensors from which the user's activity may be inferred. One or more alarms on the device may be temporarily disabled when sensor data indicates that the user is asleep. One or more of the sensors may be worn by the user and remote from the device. A wireless communication link may be used by the device to obtain remote sensor data. Data from on-board sensors in the device—such as motion sensors, location sensors, ambient light sensors, and the like—may also be used to deduce the user's current activity. User data (such as calendar entries) may also be used to determine likely user activity and set alarms accordingly. Biometric data from a second, nearby person may also be used to automatically select certain alarm modes on a first person's device.

A method, system, apparatus, and/or device to determine a condition of a user using multiple sensors. The method, system, apparatus, and/or device may include: a band configured to extend at least partially around a body part of a user having a subdermal feature within body part; a light configured in the band to emit light into the body part; a miniaturized spectrometer positioned in the band to press against the body part to receive the light, where the miniaturized spectrometer comprises: an optical filter configured to isolate a relevant constituent wavelength of the light; a collimator configured to collimate the light; and an optical sensor configured to detect an intensity of the relevant constituent wavelength; and an impedance sensor integrated into the band and configured to be positioned against a same side of the body part as the miniaturized spectrometer.

A dynamic wake-up alarm is provided-for, including a clock, a contactless biometric sensor, a processor, memory, and a speaker. The processor may be configured to receive a wake-up rule based on at least two wake-up criteria including a time from the clock and data from the biometric sensor, and evaluate whether the criteria are met to activate an alarm.

A wrist-wearable electronic device comprising first and second light emitting elements, a sensor, and a processor. The processor is configured to transmit a first command to the first light emitting element in response to the wrist-wearable device reaching a forward position relative to a user based on data received from the sensor and transmit a second command to the second light emitting element in response to the wrist-wearable device reaching a rearward position relative to the user based on the data from the sensor.

A method of a wearable device displaying icons is provided. The method includes displaying a plurality of circular icons comprising a first circular icon located in a center area of a touch display in a first size and a second circular icon located outside of the center area of the touch display in a second size smaller than the first size, and based on a direction of a touch input received on the touch display, moving the plurality of circular icons such that the first circular icon is moved to a first position located outside of the center area of the touch display and the second circular icon is moved from a second position located outside the center area of the touch display to the center area of the touch display and enlarged in size from the second size to the first size.

A wearable electronic device includes: an input module configured to receive a user manipulation for changing a configuration setting value of a main electronic device; and a communication module configured to transmit a control signal for changing a configuration setting value to the main electronic device.
