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 of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by 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 proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 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 output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

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

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to a change amount of light, and position information of the object to be sensed can be obtained through the calculation.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Referring to FIG. 2, the location of an LDAF (Long Distance Auto Focusing) sensor according to an embodiment of the present invention will be described.

Referring to FIG. 2, the LDAF sensor may be mounted on the rear surface or the front surface of the mobile terminal 100, but is not limited thereto. In the present specification, it is assumed that the LDAF sensor is mounted on the rear surface of the mobile terminal 100. [

The LDAF sensor may be disposed adjacent to the camera 121 of the mobile terminal 100 while being mounted on the rear surface of the mobile terminal 100. [ Further, the LDAF sensor 1 can be arranged on the same plane as the camera.

Hereinafter, the function of the LDAF sensor 1 will be described.

Unlike conventional proximity sensors (optical sensors), LDAF sensors can use IR Laser (Infrared Laser) as a light emitter.

The LDAF sensor 1 can measure the distance between the object to be measured and the mobile terminal 100 using an infrared laser.

The LDAF sensor 1 measures the distance from the mobile terminal 100 (or the LDAF sensor 1) by applying the ToF (Time of Flight) principle in measuring the distance between the object of measurement and the mobile terminal 100 It is a sensor that calculates the distance by measuring the light flight time to the object.

Specifically, the LDAF sensor 1 emits the light emitting body using the IR Laser, calculates the amount of light emitted from the LDAF sensor to the measurement object, and the time the light is reflected from the measurement object and returns to the LDAF sensor 1 The distance between the object and the mobile terminal 100 can be measured.

The LDAF sensor 1 is a sensor that measures a distance regardless of physical or chemical characteristics (e.g., material, color, etc.) of an object to be measured.

The LDAF sensor 1 performing this function can be used to perform an operation other than the distance measurement operation (for example, heart rate measurement) based on the above-described function.

The LDAF sensor 1 can be used in conjunction with other sensors (for example, the infrared sensor 8, the motion sensor 7, etc.) other than the LDAF sensor 1 and will be described in detail below .

3 to 13, a method of measuring heart rate using the LDAF sensor 1 according to an embodiment of the present invention will be described.

The distance measuring operation of the LDAF sensor 1 can be changed in setting. With this setting change, the LDAF sensor 1 can measure the heart rate of the finger 2. [

3 is a flowchart illustrating a method of controlling a mobile terminal for measuring heart rate using an LDAF sensor according to an embodiment of the present invention.

Referring to FIG. 3, the controller 180 obtains a request to enter the heart rate measurement mode (S301).

The control unit 180 can acquire a specific input through each sensor (for example, the LDAF sensor 1 or the like) in the mobile terminal 100.

The control unit 180 may determine whether the specific input acquired through each sensor is a request to enter the heart rate measurement mode.

If it is determined that the specific input is a request to enter the heart rate measurement mode, the controller 180 may perform an operation according to a request to enter the heart rate measurement mode.

Hereinafter, three examples of acquiring an entry request to the heart rate measuring mode will be described with reference to FIGS. 5 to 7. FIG.

As shown in Fig. 5, an example of acquiring an entry request via the finger 2 access input to the LDAF sensor 1 may be included as an example of obtaining an entry request to the heart rate measurement mode.

As an example of a method for acquiring an entry request through the access input of the finger 2, there is a gradual approach detection method of FIG. 5 (a).

5A, when the user's finger 2 approaches the LDAF sensor 1 at a certain distance from the LDAF sensor 1 (40 cm away from the LDAF sensor 1) The controller 180 can detect that the finger 2 is approaching through the LDAF sensor 1 and the user interface unit 160.

Another example of the method of acquiring the entry request through the access input of the finger 2 is the instantaneous approach detection method of FIG. 5 (b).

5 (b), when the user's finger 2 approaches (or comes into contact with) the LDAF sensor 1, the control unit 180 controls the finger (not shown) through the LDAF sensor 1 and the user interface unit 160 2) can be detected.

10, when an object other than the finger 2 is approaching a predetermined number of times or more (for example, five times) in sensing the approach of the finger 2 as described above, The control unit 180 can display an access warning message 13 through the display unit 151 indicating that the finger 2 is not the finger 2 and that the finger 2 should be approached for measuring the heart rate.

As shown in FIG. 6, another example of acquiring an entry request to the heart rate measuring mode may include a method of acquiring an entry request through a touch input to the LDAF sensor 1 more than a predetermined number of times.

6, when the LDAF sensor 1 detects twice (a predetermined number of times or more) a touch (double touch), the controller 180 detects two touches detected by the LDAF sensor 1 as a heart rate It can be recognized as a request to enter the measurement mode.

As shown in FIG. 7, another method of acquiring an entry into the heart rate measurement mode may include a method of acquiring an entry request through selection of the heart rate measurement mode menu 12 displayed on the touch screen.

Referring to FIG. 7, the control unit 180 may control the display unit 151 to display a menu "Enter Heart Rate Measurement Mode?" (Heart Rate Measurement Mode Menu 12). When the selection of the heart rate measurement mode menu 12 is obtained, the controller 180 can recognize the selection of the heart rate measurement mode as a request to enter the heart rate measurement mode.

On the other hand, as shown in Fig. 8, when the finger 2 is moved toward the LDAF sensor 1 by the LDAF sensor 1 and then moved away from the LDAF sensor 1 by a predetermined distance d1 or more When the changing state is detected, the control unit 180 can recognize that the state change of the finger 2 is a request to release the heart rate measurement mode.

When the release request is recognized, the control unit 180 changes the operation setting of the LDAF sensor 1 from the heart rate measurement mode to the distance measurement mode, and simultaneously controls the LDAF sensor 1 to sense the distance measurement with the external object have.

Referring again to FIG. 3, when a request to enter the heart rate measurement mode is obtained, the controller 180 sets the operation setting of the LDAF sensor 1 to the heart rate measurement mode (S303).

The operation setting of the LDAF sensor 1 may include setting a sampling rate, a data acquisition period (Convergence Time), and a sensitivity (Convergence Count Threshold).

4 is a table showing a method of setting the LDAF sensor to the heart rate measurement mode.

Referring to FIG. 4, the controller 180 may set the operation setting of the LDAF sensor 1 optimized for distance measurement to a heart rate measurement mode for measuring the heart rate.

The controller 180 sets the operation setting of the LDAF sensor 1 to the heart rate measurement mode PPG without changing the mechanical characteristic (or hardware characteristic) of the LDAF sensor 1 itself and the LDAF sensor 1 (Or software characteristic) of the LDAF sensor 1 can be changed to set the operation setting of the LDAF sensor 1 to the heart rate measurement mode.

4, the control unit 180 sets the sampling period of the LDAF sensor 1 to 20 Hz (heart rate measurement mode) for the heart rate measurement (PPG) at a set period (for example, 50 Hz) Of the sampling period).

4, the controller 180 can set the data acquisition period (Convergence Time) of the LDAF sensor 1 to a value increased from 50 ms to 100 ms (heart rate measurement mode Convergence Time) for heart rate measurement .

4, the controller 180 sets the Convergence Count Threshold of the LDAF sensor 1 to 40 (relative value) to 7812500 (Convergence Time of the heart rate measurement mode) (relative value) for heart rate measurement .

The operation set values of each of the set LDAF sensors 1 described above are merely illustrative, and the present invention is not limited thereto. The control unit 180 may set the operation setting of the LDAF sensor 1 to an appropriate value for measuring the heart rate.

3, when the operation setting of the LDAF sensor 1 is set to the heart rate measurement mode, the control unit 180 causes the LDAF sensor 1 to measure the heart rate of the finger 2 close to the LDAF sensor 1 (S305).

The LDAF sensor 1 emits the IR Laser toward the adjacent finger 2 and measures the heart rate of the finger 2 by the amount of light received by the LDAF sensor 1 after being emitted.

9, when the LDAF sensor 1 detects the approaching state of the finger 2, the control unit 180 controls the display unit 151 to display the cursor 3 on the display screen can do.

As an example of the cursor 3, it may be a semi-transparent cursor 3. The color of the cursor 3 may be white, but it is not limited thereto.

As another example of the cursor 3, a hovering cursor may be included.

When the finger 2 is brought into contact with the LDAF sensor 1 while the finger 2 approaches the LDAF sensor 1 and the finger 2 comes into contact with the LDAF sensor 1 for a certain period of time 2 seconds), the control unit 180 can control the display unit 151 to display the cursor 3 whose size gradually increases.
