First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing in the vicinity without mechanical contact using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or in the vicinity of the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like.

In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and furthermore, provides visual information corresponding to the processed data.

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the position of the wave source based on information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source may be calculated using the property that light is much faster than ultrasonic waves, that is, the time at which light arrives at the optical sensor is much faster than the time at which ultrasonic waves reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated by using a time difference from the time that the ultrasonic wave arrives using light as a reference signal.

The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the motion of the sensing target close to the touch screen. More specifically, the photo sensor mounts photo diodes and transistors (TRs) in rows/columns and scans the contents placed on the photo sensor using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing target according to the amount of change in light, and through this, location information of the sensing target can be obtained.

Also, when the watch hand 202 functions as a minute hand, the image object 420 corresponding to the minute hand and the watch hand 202 may be located at the same radius 440 .

Although not shown, when the watch hand 202 functions as the hour or second hand instead of the minute hand, the same radius as the image object 410 corresponding to the hour hand or the image object 430 corresponding to the second hand, respectively may be located in

As a second embodiment, referring to FIG. 4B , the image objects 420 and 430 corresponding to the minute and second hands are output to the first display unit 2511 , and the image object 410 corresponding to the hour hand. may be output to the second display unit 2512 . More specifically, when the second display unit 2512 includes a plurality of light sources, only the light source corresponding to the position of the hour hand among the plurality of light sources may be activated, and the other light sources may be deactivated. Alternatively, the controller may control the plurality of light sources so that the color of the light emitted from the light source corresponding to the position of the hour hand among the plurality of light sources is distinguished from the color of the light emitted from the other light sources.

Meanwhile, the controller 280 may determine whether a user is present in the vicinity of the smart watch using an image input through the camera 221 or a sensing signal measured by the sensing unit 240 . Alternatively, based on the preset signal strength of the mobile terminal 100 sensed through the wireless communication unit 210, it may be determined whether a user is present in the vicinity of the smart watch.

Meanwhile, according to the present invention, in addition to displaying the current time, various information related to time may be displayed on the display unit. Hereinafter, this will be looked at in more detail.

5 is a conceptual diagram illustrating a method of controlling a display unit to display information related to an image of a subject included in an image input through a camera.

The smart watch 200 according to the present invention may include a camera 221 . More specifically, the body 201 may be provided with a camera 221 . The camera 221 may be disposed on the main body 201 such that the photographing direction faces the same direction as the display unit 251 .

An image including an image of a subject may be input through the camera 221 . For example, when the distance between the smart watch 200 (more specifically, a distance sensor) and the subject is within a preset distance, the controller 280 controls the camera 221 to take pictures of the subject. can be controlled

The controller 280 may recognize an image of a subject included in an image input through the camera 221 . More specifically, the controller 280 may specify an image of a subject included in the image based on a preset face recognition algorithm.

The controller 280 may control the display unit 251 to display information related to the image of the subject based on the recognized image of the subject.

Referring to FIG. 5A , as described above, the control unit 280 may control the display unit 251 to output screen information indicating time by using the position of the clock hand 202 . have. More specifically, when the watch hand 202 functions as a minute hand, the controller 280 may control the display unit 251 to output the image object 520 at a position corresponding to the hour hand.

Referring to FIG. 5B , the controller 280 recognizes an image of a subject included in an image input through the camera 221 and displays information related to the recognized image of the subject on the display unit 251 . ) can be controlled.

For example, when the image of the subject A is recognized through the camera 221 , certain information 520a and 520b related to the recognized subject A may be output to the display unit 251 . More specifically, the controller 280 may display the schedule information 520a and 520b at a position corresponding to a clock scale related to the schedule.

Meanwhile, the schedule information 520a and 520b may be transmitted from a preset mobile terminal 100 communicating with the smart watch 200 through the wireless communication unit 210 . In other words, when schedule information is input to the mobile terminal 100 by the user, the smart watch 200 may receive the schedule information in real time through the wireless communication unit 210 . The schedule information transmitted in real time may be temporarily stored in the memory of the smart watch 200 .

Referring to FIG. 5C , the information related to the recognized subject image may be information 540 regarding an event occurring in the preset mobile terminal 100 in addition to schedule information related to the subject.

Furthermore, the controller 280 may control the display unit 251 to output information 530a and 530b related to the operation of the external home appliance.

In this case, the information 530a and 530b related to the operation of the external home appliance may be output together with the information 510 related to the current time. In addition, the information 530a and 530b related to the operation of the external home appliance may be displayed in a different color from the information 510 related to the current time. Accordingly, the user can easily recognize the current time and information related to the operation of the external home appliance at the same time.

For example, when the external home appliance is a washing machine, when an operation of the washing machine starts, the control unit 280 may receive information related to washing time through the wireless communication unit 210 .

Also, the controller 280 may receive information about a subject related to the operation of the washing machine together with the received washing time related information. In this case, the information about the subject may be linked together with the information related to the washing time. Accordingly, based on the image of the subject included in the image input by the camera 221 according to the present invention, information related to the washing time associated with the information about the subject may be output to the display unit 251 .

Meanwhile, when there are a plurality of object images recognized in the image input through the camera, information related to the plurality of objects may be output to the display unit at once or sequentially. When sequentially output, the information related to the plurality of subjects may be sequentially output according to the time sequence of the predetermined information included in the information.

Furthermore, when a plurality of subject images are recognized in the image, when at least one subject image is not a previously registered subject image, for privacy protection, all information related to the plurality of subjects may not be output to the display unit. .

On the other hand, the watch hand 202 related to the present invention is formed to be rotatable by the driving force provided from the driving unit 230 to display the current time.

After reaching the second position, the watch hand 202 may return to a third position adjacent to the first position when the external force is released. Here, the difference between the first position and the third position may be a result of reflecting time passed while the watch hand 202 is moved. When the time elapsed while the watch hand 202 is moved is within 1 minute, the first position and the third position may be the same position.

Alternatively, the clock hand 202 may be formed to return to a position corresponding to the current time after a preset time (eg, several seconds) passes at the time when the external force is released.

Meanwhile, the controller 280 may generate notification information related to a time corresponding to the changed position of the watch hand 202 .

6A (c) and 6A (d), after the clock hand 202 returns to the position corresponding to the current time, as time passes, the position corresponding to the position where the graphic object 620 is displayed , the notification information may be output. In other words, when the current time reaches a time corresponding to the position of the clock hand 202 previously changed by an external force, the control unit 280 displays the notification information 630 to the display unit 251 or the sound output unit 252 . It can be output through
