One-touch transmission and one-touch silencing of a wearable group communication device utilize an end user device body and face that can be moved relative to one another in one or more simple, single-motion actions. One-touch audio transmission is enabled after an end user device is activated to enable communications. Depressing the end user device face relative to the end user device body enables audio transmission. While the face is in its depressed position audio can be transmitted. To cease audio transmission the face is released. One-touch audio silencing of an activated end user device can be performed by rotating the face relative to the body to silence audio broadcast.

An electronic device and a system including the same are disclosed. An electronic device of the present invention includes: a body; a plurality of supports each of which is coupled to the body through one side thereof; and a holder configured to connect other sides of the plurality of supports having a curved portion corresponding to the shape of the ear of a user and fitted in the ear of the user, wherein at least one of the plurality of supports rotates on the body, wherein the radius of the holder is changed according to rotation of the at least one of the plurality of supports. According to the present invention, the supports coupled to the body rotate to be fixed to the user's ear.

The present disclosure provides an electronic device, including: a movable body having at least one functional unit and a main body. The movable body is movable from a first position to a second position with respect to the main body, the main body has a first surface provided with a first display unit, the movable body includes a second surface, a long side of the second surface has a length identical to a length of a short side of the first surface. The first surface and the second surface are both located in a first plane when the movable body is located in the first position with respect to the main body.

An electronic apparatus includes: a hosing including a first facing wall portion and a second facing wall portion which face each other; a cable provided in the housing; and a restriction portion, provided between the first facing wall portion and the second facing wall portion, configured to restrict the first facing wall portion and the second facing wall portion to approach with each other and to retain the cable.

A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer. By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment of an interesting event is expected to be captured. The small size of the recall device makes it possible to integrate it into common portable consumer products, such as MP3 players, purses, clothing, hats, backpacks, necklaces, collars, and other human-wearable products.

A mobile terminal includes a sub-device that is attached thereto or detached therefrom, to remotely control the operation and state of the terminal. The mobile terminal includes: a sub-device having an input/output unit and attached to or detached from the terminal; and a controller configured to receive a user input via a certain communication path from the sub-device when the sub-device is separated, and control elements and applications of the terminal according to the user input.
