The rear input unit may be implemented in a form capable of inputting by a touch input, a push input, or a combination thereof.

The rear input unit may be disposed to overlap the front display unit 151 in the thickness direction of the terminal body. For example, when the user holds the terminal body with one hand, the rear input unit may be disposed on the rear upper end of the terminal body so that the user can easily manipulate the terminal body using the index finger. However, the present invention is not necessarily limited thereto, and the position of the rear input unit may be changed.

When the rear input unit is provided on the rear surface of the terminal body, a new type of user interface can be implemented using the rear input unit. In addition, when the touch screen or the rear input unit described above replaces at least some functions of the home button 123a provided on the front of the terminal body, and the home button 123a is not disposed on the front of the terminal body, the display unit 151 ) Can be configured as a larger screen.

In the case of having a physical button, since the side button 123b is inserted into the button hole 104a formed in the side case 104, a waterproof part 1238 is required to block water from flowing into the button hole 104a. . The waterproofing part 1238 is also important in waterproofing performance, but it is necessary to minimize the increase in volume or complexity of the process by adding the waterproofing part.

2 is a perspective view showing an example of a wearable device 300 related to another embodiment of the present invention.

Referring to FIG. 2, the wearable device according to the present invention may be a watch-type wearable device 300. However, the wearable device 300 according to the present invention is not limited to a watch type wearable device, and includes an integral wearable mobile device 100 such as an earphone type, a band type, a clothing type, or a glass type.

The watch-type wearable device 300 includes a main body 301 having a display unit 351 and a band 302 connected to the main body 301 and configured to be worn on a wrist. In general, the wearable device 300 may include features of the mobile device 100 of FIGS. 1A to 1C or similar features.

The watch-type wearable device 300 is configured to enable wireless communication, and an antenna for the wireless communication may be installed in the main body 301. On the other hand, the antenna can extend its performance by using a case. For example, a case including a conductive material may be configured to be electrically connected to an antenna to expand a ground region or a radiation region.

A display unit 351 may be disposed on the front surface of the main body 301 to output information, and a touch sensor may be provided on the display unit 351 to be implemented as a touch screen.

The fastener 302a may be implemented by a buckle, a hook structure capable of snap-fit, or velcro (trade name), and may include an elastic section or material. . In this drawing, an example in which the fastener 302a is implemented in the form of a buckle is shown.

Watch-type wearable devices currently on the market are generally used in pairs with other terminals (eg, bar-type smart phones). For example, when a watch-type wearable device and a bar-type smart phone are paired based on Bluetooth communication, the watch-type wearable device outputs data (eg, weather information, schedule information, or call log) received from the smart phone. , The control signal for remote control of the smart phone can be transmitted to the smart phone.

For example, the controller 180 may set the effective angle range through an input unit or an external device interlocked with the wearable device 300. The controller 180 may analyze the sensed ultraviolet light data and set an effective angle range. The controller 180 may set an angle range in which ultraviolet data is highly sensed as an effective angle range. For example, the controller 180 may set an angle range including a value larger than a value obtained by multiplying the largest ultraviolet data value by a predetermined ratio as the effective angle range. The controller 180 may select UV data within a preset angle range as valid data.

Referring to FIG. 9A, the controller 180 may set a specific pitch angle range as an effective angle range. The controller 180 may select ultraviolet data within a specific pitch angle range as valid data. Here, the controller 180 may select the largest value among the ultraviolet data as valid data. For example, the specific pitch angle range may be a pitch angle range of 45 degrees or less and 315 degrees or more.

Referring to FIG. 9B, the controller 180 may set a specific roll angle range as an effective angle range. The controller 180 may select ultraviolet data within a specific roll angle range as valid data. Here, the controller 180 may select the largest value among the ultraviolet data as valid data.

10 is a diagram illustrating a method of providing a notification service according to an average value of selected data according to an embodiment of the present invention. The present invention is implemented by the controller 180.

The controller 180 may output an event by comparing the average value of the selected data with reference data. Here, the average value may be a moving average value of UV data measured during the first set time. For example, the average value may be an average value of UV data 5 minutes before the reference time point.

The controller 180 may acquire and select ultraviolet data at every second set time interval. Here, the second setting time may be shorter than the first setting time. For example, the controller 180 may acquire ultraviolet data every minute and select ultraviolet data within an effective angle range as valid data.

The controller 180 may assign a weight to the selected data according to a sensing angle. The controller 180 may compare weighted values to extract a representative value and compare it with reference data.

The controller 180 may output a notification service when the average value or the representative value exceeds a preset criterion. Here, the controller 180 may control an output unit or an external device interlocked with the wearable device 300 to output a notification service. For example, the notification service may be a vibration, a text message, or a voice message. The controller 180 may output events differently according to the risk of ultraviolet rays based on the reference data.

The controller 180 may set a different setting time according to a condition for sensing ultraviolet rays. For example, in the case of indoors, the controller 180 may set the first set time to 1 hour.

The controller 180 may delete UV data stored before the first set time. The controller 180 may store only ultraviolet data related to an event. Accordingly, the present invention can lower the data processing load of the device and the external server compared to the case of storing data in real time or transmitting it to an external device.

Referring to FIG. 11B, the reference data may be an ultraviolet index stored in the memory 170 or an external device. For example, the controller 180 may compare the selected UV data with the Global Solar UV Index issued by the International Health Organization (WHO) in connection with an external device. The controller 180 may receive reference data from an external server or an external device and store it in the memory 170.

According to an exemplary embodiment of the present invention, the present invention may provide accurate ultraviolet data within an effective angle range based on an angle at which the ultraviolet sensor senses ultraviolet rays.

According to another embodiment of the present invention, an average UV value is calculated based on the selected data, and only UV data above a reference value is stored or transmitted to reduce a data processing load.

The processor-readable recording medium includes all types of recording devices that store data that can be read by the processor. Examples of recording media that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and also include those implemented in the form of carrier waves such as transmission through the Internet. . Further, the processor-readable recording medium is distributed over a computer system connected through a network, so that the processor-readable code can be stored and executed in a distributed manner.
