An information terminal is used with a wrist information device. The information terminal includes a position measurement module, communication circuit, a memory, and a processor. The position measurement module obtains position information. The communication circuit communicates with the wrist information device. The processor obtains information about an operation of a clock function input into the wrist information device during establishment of connection of the communication, obtains the position information from the position measurement module, and stores, in the memory, the position information and the information about the operation of the clock function in association with each other.

This invention is a smart watch or other wrist-worn device with one or more cameras and a display which enables a person wearing the device to aim the focal direction of imaging while keeping with their arm in a comfortable, non-contorted configuration. The display can serve as a view finder for a camera. An arcuate array of cameras can be distributed around a portion of the circumference of the person's wrist and one camera from the array can be selected to record images from a particular angle at a particular time.

An electronic device includes: a TFT liquid crystal panel; a light source that emits light to be radiated onto a back face of the TFT liquid crystal panel; and a processor that generates a common signal to be input to a common electrode of the TFT liquid crystal panel. The processor generates the common signal so as to have a waveform that differs between when the light source is not lit and when the light source is lit.

A user performing a water sport is appropriately supported. A wrist terminal includes an LCD and an output control unit. The output control unit measures a time from when a swell of a wave occurs or passes until the swell breaks. In addition, the output control unit causes the LCD to display time information of the measured time.

Various systems and methods for providing a separatable wearable device are provided herein. A detachable portion of a wearable device includes a microcontroller; a memory coupled to the microcontroller; a battery assembly coupled to the microcontroller; and a display coupled to the microcontroller, wherein the microcontroller is to: operate in a first mode when the detachable portion is coupled to a holder portion of the wearable device; and operate in a second mode when the detachable portion is decoupled from the holder portion, and being recharged.

A device includes a context engine and a notification engine. The context engine determines a context indicator relative to received input while the notification engine selects, based on the context indicator and the received input, at least one type of notification from different types of notifications. A wearable electronic arrangement selectively communicates, and senses for different types of single user response to, at least a portion of the received input via the selected type of notification. The context engine receives feedback regarding the sensible different types of single user response to at least partially determine the context indicator.

A mobile terminal and a method for controlling the mobile terminal are disclosed. The present invention includes a band wearable on a user's body, a display, and a controller configured to display, via the display, a clock area at a center of the display, cause to the display to move the clock area to an edge of the display corresponding to a first drag input when the first drag input is received on the clock area, and display, via the display, an notification icon at the center. According to an embodiment of the present invention, notification contents may be dynamically displayed according to user's interaction.
