An electronic watch includes a housing defining a side surface of the electronic watch, a transparent cover coupled to the housing and defining a front surface of the electronic watch, an image-sensing element, and a crown extending from the side of the housing and defining an imaging surface. The crown may include a light-directing feature configured to direct, onto the image-sensing element, an image of an object in contact with the imaging surface.

A method and an electronic device implementing the method are disclosed. The electronic device may include sensors, a memory and a processor executing instructions stored in the memory to: select at least one sensor of the one or more sensors to detect movement of the electronic device and select a sampling frequency of the selected at least one sensor based on usage state information of the electronic device, detect the movement of the electronic device using the selected at least one sensor at the selected sampling frequency, and when the detected movement corresponds to at least one preset condition of the one or more preset conditions, execute a specific application of the one or more applications associated with the at least one preset condition.

A wrist apparatus as a portable electronic apparatus calculates an evaluation value based on data outputted from acceleration sensors, each of which serves as an inertia sensor, and assuming that when the evaluation value becomes greater than a first threshold, it is determined that a first state has been achieved, and when the evaluation value becomes smaller than a second threshold, it is determined that a second state has been achieved, performs a predetermined display when a result of the determination shows that the first state has transitioned to the second state.

A hand position control device includes a mode switching unit that is capable of switching between a normal hand movement mode and a manual hand position setting mode and a control unit that sets a pulse width of a driving pulse to be output to a coil of a motor that rotates a hand and sets a manual pulse width of the driving pulse in the manual hand position setting mode to be larger than a normal pulse width of the driving pulse in the normal hand movement mode.

The present invention relates to a method and apparatus for processing a wearing state of a wearable device. Embodiments of the present invention achieve the purpose of obtaining an actual wearing state of the wearable device by obtaining a space quaternion parameter of the wearable device worn by the user, then obtaining a posture angle of the wearable device according to the space quaternion parameter, and then obtaining a measurement wearing state of the wearable device according to the posture angle of the wearable device.

For indirect determination of digit movement, apparatus, methods, and computer program products are disclosed. The apparatus for indirect determination of finger movement includes a processor and a memory that stores code executable by the processor. The processor obtains frequency data corresponding to movement of a user's limb, extracts frequency data having a predetermined feature value from the measured frequency data; and determines from the extracted frequency data whether the movement of the limb corresponds to a predetermined digit motion.

A wearable device includes a dial, a watch body, and a position detection member. The position detection member includes a first component and a second component, one of the first component and the second component is arranged on the dial, the other of the first component and the second component is arranged on the watch body. The first component includes a first subcomponent and a second subcomponent, and the first subcomponent and the second subcomponent are spaced from each other in a rotation direction of the watch body. The position detection member has a first state and a second state, when the position detection member is in the first state, the first subcomponent is opposite to the second component, and when the position detection member is in the second state, the second subcomponent is opposite to the second component.
