An electronic device that can be worn on a limb of a user can include a processing device and one or more position sensing devices operatively connected to the processing device. The processing device can be adapted to determine which limb of the user is wearing the electronic device based on one or more signals received from at least one position sensing device.

A method includes providing wireless communication between a device having a holography module and a watch. The watch is being worn by a user and has sensors. The holography module outputs one or more holographic objects in three-dimensional space. User's selection of one of the holographic objects is detected by the watch. Direction of rotation of a crown of the watch is detected and rotational speed of the crown of the watch is measured by the watch. The watch communicates to the holography module the direction of rotation of the crown and the rotational speed of the crown. The holography module changes position of the selected holographic object by moving the selected holographic object. Direction of movement of the selected holographic object corresponds to the direction of rotation of the crown. Speed of the movement of the selected holographic object corresponds to the rotational speed of the crown.

An electronic timepiece includes: a main unit having a reporting unit that reports information to a user; a crown that can be pulled out from and pushed back into a main unit by the user; a sensor that detects a state of the electronic timepiece; and a processor, wherein the processor detects a state of the crown and the state detected by the sensor and switches between a plurality of modes in accordance with the state of the crown, and wherein upon detecting that the crown has been pulled out or pushed back in, the processor causes the electronic timepiece to operate in a state reporting mode in which the reporting unit reports the state detected by the sensor to the user.

A smart watch interacting method comprises: obtaining a rotation direction and rate information of a rotary knob; obtaining a displacement information of the rotary knob; querying an interacting mapping library to determine an operation instruction according to the rotation direction and rate information and the displacement information of the rotary knob; and displaying an interacting operation on the user interface according to the operation instruction.

The present disclosure generally relates to interacting with an electronic device without touching a display screen or other physical input mechanisms. In some examples, the electronic device performs an operation in response to a positioning of a user's hand and/or an orientation of the electronic device.

A compact crown for an electronic device such as an electronic watch, including a set of wipers capable of determining a rotation angle, rotation direction, or rotation speed, is disclosed. The set of wipers is in contact with at least one resistance member at different angular positions around a rotation axis. The crown may have a group of ground taps disposed along the resistance member and a measured signal may vary based on the position of each wiper as it contacts the at least one resistance member. A compact crown may also include capacitive members and capacitive sensors in order to similarly determine rotation angle, rotation direction, or rotation speed.

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 timepiece illusion device is formed to appear as an ordinary analog watch or timepiece with hour and minute hands. A software application (Illusion App) is provided that can be loaded onto a smartphone or other device. The Illusion App allows a user to provide inputs into the smartphone, which are transmitted (e.g., as time commands, etc.) from the smartphone to the timepiece illusion device. The timepiece illusion device then moves the hour and minute hands per the time command or otherwise performs the relevant operation per the input from the smartphone.

A rotation detecting apparatus includes a rotating member, detectors regarding a rotating direction of the rotating member, and a predetermined unit. Each detector detects whether a predetermined standard direction is included in detecting ranges different for each rotating member and outputs a result. The predetermined unit combines the detection result output from each detector and extracts an angle range. The predetermined unit specifies the rotating direction of the rotating member based on changes in the angle ranges extracted a plurality of times occurring in the plurality of times. The detecting range corresponding to each of the plurality of detectors is determined to be able to identify relative positions before and after a change from the angle range extracted by the predetermined unit to the angle range that is clockwise or counterclockwise apart a predetermined number or less to the angle range extracted, the predetermined number being two or more.

One embodiment described herein takes the form of a watch, comprising: a housing; a crown comprising: a crown body outside the housing; and a shaft extending from the crown body into the housing; and an actuator coupled to the crown and configured to provide haptic output through the crown.
