It can be transmitted to the image display device 100 through.
The controller 280 may control the received personal information to be transmitted to the image display apparatus 100 through the wireless communication unit 220 through an electronic device and near field communication. In particular, when there is a predetermined key input by the user input unit 230, the controller 280 may control the received personal information to be transmitted to the image display apparatus 100 through the wireless communication unit 220.
In addition, the controller 280 may control the received personal information to be transmitted to other electronic devices other than the image display apparatus 100.

7 and 8 are views for explaining the operation method of the remote control apparatus according to an embodiment of the present invention.
The remote control apparatus according to the embodiment of the present invention controls electronic devices such as an image display apparatus using motion. In more detail, the pointer and the predetermined operation may be performed based on the motion information of the remote controller.
FIG. 7 shows an example in which the work area 711 when an adult uses the remote control device 201 and the work area 712 when a child uses the remote control device 201 are set identically.
On the other hand, the work area may mean an area in which a pointing device type remote control device can move to control the pointer 205 of the display 180.
In the case of a method of controlling a pointer based on the sensing data of the sensor unit 240 described with reference to FIG. 5, the work area may include a feedback sensitivity according to the movement of the remote controller 200, for example. This may be a criterion for determining the degree of movement of the pointer.
Alternatively, in the case of providing a pointer 205 by recognizing the position of an IR lamp, for example, an IR LED, provided in the remote control device as the infrared camera 160, the working area is the infrared camera 160. It may be an area to recognize the movement of the remote control device.
On the other hand, as shown in Figure 7, if the user always uses the same work area irrespective of the user, the user must use the same work area unconditionally at the same distance without considering the user's body characteristics such as arm length, height, disability There is this.
Although it may be a work area without discomfort for the general adult, if the same work area as the general adult is applied to a child or a disabled person with a limited movement of the arm, discomfort may be caused.
Therefore, the remote control apparatus according to an embodiment of the present invention, the interface unit 220 for transmitting and receiving a signal with the image display device 100, a plurality of sensors for detecting the presence or absence of contact, for example, contact sensor 245 and The controller 280 estimates the user's body data based on the number of sensors in which the contact is detected among the plurality of sensors.
In addition, the controller 280 may estimate the user's body data in consideration of the position where the sensor is detected.
The storage unit 270 may store physical data and / or statistical data for estimating a work area of a user supplied by a manufacturer or a service provider, and the statistical data may be updated.
The statistical data may be data obtained by collecting the number of sensors detected according to the physical characteristics of a large number of samples (large number of users), and arranging corresponding values statistically to form a database.
For example, the statistical data may include at least one body data such as a hand size, an arm length, a height, and the like corresponding to the number and / or location of a sensor where a contact is detected.
In addition, the statistical data may include size information of an optimized working area according to the estimated body data.
In order to further improve the accuracy of the determination, the controller 280 may use a mean value after extracting a plurality of data having an approximation to the number of sensors among the statistical data of the storage unit 270. For example, the body data value calculated by averaging four body data corresponding to four values closest to the number of sensors for which touch is detected may be used.
The controller 280 may set a work area of the remote controller based on the estimated body data. That is, according to the present invention, it is possible to use a work area in consideration of the user's body characteristics.
The statistical data may divide the body data into a plurality of groups and allocate a size of an optimized work area for each group.
In this case, the controller 280 may determine the size of the work area according to the optimized work area size information allocated to the estimated body data.
Alternatively, the controller 280 may use a mean value after extracting a plurality of data having an approximation to the estimated body data among the statistical data of the storage unit 270.
8 shows a working area 811 when a tall person, an adult uses the remote control device 201, and a working area 812 when a short person, a child uses the remote control device 201. FIG. An example of large setting is shown.
The controller 280 may determine the size of the user's hand based on the number of sensors for which the contact is detected, and infer other body data based on the determined size of the hand.
In general, hands are part of the body, so their shape or size changes as they grow, and the size of the hand is proportional to the length of the arm of the person.
Therefore, by measuring the size of the hand, it is possible to estimate the body characteristics of the user such as the arm length and height, thereby automatically setting the work area suitable for the user.
Accordingly, the user's satisfaction and convenience can be improved due to the improved usability of the remote control device.

In this case, the controller 280 may control the controller to transmit a signal based on the movement of the remote controller differently according to the size of the work area. For example, a value obtained by multiplying the magnitude of the movement of the remote controller by the scaling factor by the scaling factor may be transmitted as the magnitude value.
Alternatively, the signal based on the movement of the remote control device, when the work area is set to a second size larger than the first size, the feedback of a smaller intensity than the case of being set to the first size, the image The display device may be a signal for controlling the output. For example, the remote control apparatus 200 may include a signal for controlling to have a different feedback sensitivity according to the size of the work area, or transmit a signal including the size information of the work area to the image display device 100. .
On the other hand, according to one embodiment of the present invention, in the case of a special condition, such as a person with a discomfort, a disabled person, by providing a menu (UI) that can change the automatically set work area, the user can select a work area suitable for Can be set.

In this case, the signal may be different according to the size of the working area, and when the working area is set to a second size larger than the first size, the feedback having a smaller intensity than that set to the first size It may be a signal for controlling to output the image display device.
10A and 10B illustrate a work area 1011 set to a first size and a work area 1012 set to a second size relatively larger than the first size.
Even if the user moves the remote controller by the same size (a), it is possible to output a different size of feedback.
When the user's hand, arm, etc. are small, it may be cumbersome to move the remote control device 200 many times in order to move the pointer 205 to a desired position. Therefore, in this case, the present invention can move the pointer by a relatively large size b when the remote control device is moved by the same size a.
In addition, when the user's hand, arm, etc. are large, the pointer may be moved by a relatively small size (c) in the case of an adult.
Therefore, the feedback strength optimized for the user can be set.
On the other hand, the working area may be a sensing area for detecting the movement of the remote control device.

In addition, the controller 170 may infer the body data of the user based on the received signal and set the work area accordingly.
Alternatively, when the remote control apparatus 200 estimates the body data and transmits a signal including the estimated information in the transmitting step S1120, the image display apparatus 100 based on the estimated information, the work area. You can also set
Thereafter, when the remote controller transmits a signal including motion information (S1140), the image display apparatus 100 may output different feedback according to the set working area size (S1150).
That is, the embodiment described with reference to FIG. 11 is different from other embodiments in that the work area is set by the image display device 100 instead of the remote control device 200.
