Meanwhile, the sensing unit 140 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a sensing signal corresponding thereto. The controller 180 may control the driving or operation of the mobile terminal 100 or perform data processing, functions, or operations related to an application program installed in the mobile terminal 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

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, and an infrared proximity sensor. When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of an object having conductivity by a change in an electric field according to the proximity of the object. 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 further, provides visual information corresponding to the processed data. It can be printed on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. do.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or a change in capacitance occurring in a specific part of the touch screen into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of a touch, an electrostatic capacitance at the time of a touch, etc. in which a touch object applying a touch on the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, when there is a touch input to the touch sensor, a signal(s) corresponding thereto is sent to the touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the controller 180 . Accordingly, the controller 180 can know which area of the display unit 151 has been touched, and the like. Here, the touch controller may be a component separate from the controller 180 , or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or may perform the same control according to the type of the touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different controls or the same control according to the type of the touch object may be determined according to the current operating state of the mobile terminal 100 or a running application program.

On the other hand, the above-described touch sensor and proximity sensor are independently or in combination, a short (or tap) touch on the touch screen (short touch), long touch (long touch), multi touch (multi touch), drag touch (drag touch) ), flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch, etc. It can sense touch.

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 through 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 for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference between the time that the ultrasonic wave arrives using light as the reference signal.

On the other hand, the camera 121 as seen in the configuration of the input unit 120 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing target for a 3D stereoscopic image.

A home automation system and a control method thereof according to an embodiment of the present invention may perform data communication with electronic devices using various network protocols. This improves the network compatibility of the home automation system.

Accordingly, since the user is not limited by the network properties of the electronic device when using the home automation system, user convenience is increased.

The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded. The computer-readable medium includes all types of recording devices in which data readable by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is also a carrier wave (eg, transmission over the Internet) that is implemented in the form of. In addition, the computer may include the control unit 180 of the terminal. Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.
