Description

TECHNICAL FIELD [0001] The present invention relates to a display device controlled by a pointing device and a control method thereof. BACKGROUND OF THE INVENTION [0002]

The present invention relates to a multimedia device, and more particularly, to a display device controlled by a pointing device and a technique related to the control method.

With the spread of smart TVs, the number of tasks that users have to control increases, and the user interface (UI) becomes more complex. Pointing devices are also used in view of such problems.

However, the pointing device according to the related art has a problem in that a situation unexpectedly occurs according to the position.

Furthermore, the present invention will be described by taking the television as an example, but the scope of the right should naturally be determined according to the matters described in the claims, and therefore applicable to all display devices such as TVs, projectors and the like.

An aspect of the present invention is to utilize the advantages of an absolute coordinate system and an advantage of a relative coordinate system in a process of controlling a display device using a pointing device. The absolute coordinate system and the relative coordinate system will be described later in detail. Meanwhile, the absolute coordinate system is processed using, for example, an infrared camera, and the relative coordinate system is processed using, for example, a gyro sensor.

The absolute coordinate system is created using at least one infrared LED mounted on the exterior of the display device, and coincides with the direction in which the pointing device is oriented in the screen of the display device. Therefore, the user can locate the pointing cursor at a position coinciding with the vector of the direction pointing to when the pointing device is used, thereby ensuring intuitiveness. In addition, it prevents the problem of the user's wrist bend occurring in the relative coordinate system.

When the pointing point of the pointing device moves to the area where the LED position is not recognized in the absolute coordinate system, it is directly converted to the relative coordinate system. At this time, coordinates are generated by the acceleration values of the gyro sensor x, y and z axes. In the relative coordinate system, the user can utilize the advantage of pointing without having to orient the screen.

When the pointing device re-enters the area where the absolute coordinate system can be recognized in the relative coordinate system, it is switched back to the absolute coordinate system.

A display device controlled by a pointing device according to an embodiment of the present invention may include at least one sensor (the sensors are located at positions spaced apart from each other) provided on the display device, and a pointing device When the pointing point to which the pointing device is directed belongs to the first area, the position of the pointer is adjusted to correspond to the pointing point of the pointing device, and when the pointing point to which the pointing device is pointing belongs to the second area, A controller for adjusting the position of the pointer based on the position of the pointer, and a display module for outputting the pointer adjusted by the controller to the screen.

A method of controlling a display device controlled by a pointing device according to an embodiment of the present invention includes the steps of sensing the pointing device using at least one sensor installed in the display device, The method comprising the steps of: adjusting a position of a pointer to correspond to a pointing point of the pointing device when the pointing point to which the device is directed belongs to the first area; Adjusting the position of the pointer based on the movement of the pointing device when the pointer is located on the screen of the display device; and outputting the position-adjusted pointer on the screen of the display device.

According to an embodiment of the present invention, a space pointing method in which an absolute coordinate system and a relative coordinate system are combined is provided to a user, thereby enhancing intuitiveness to a user and reducing problems such as wrist bending.

According to another embodiment of the present invention, in order to prevent the user from recognizing the miss alignment as much as possible when entering the absolute coordinate area in the relative coordinate area, the correction process is automatically performed in proportion to the speed of the pointing device .

Furthermore, according to another embodiment of the present invention, there is an advantage of stopping the correction for miss alignment when the motion of the pointing device is detected and there is no motion.

According to another embodiment of the present invention, the final point of orientation in which the shaking operation is performed is classified into the absolute coordinate / relative coordinate region, and the cursor is positioned at the corresponding point in the absolute coordinate region. In the relative coordinate region, There is a technical effect to move to a specific point (ex: center) set.

5 is a view illustrating a display device and a pointing device according to another embodiment of the present invention. The pointing device according to an embodiment of the present invention will be briefly described with reference to Figs. 1 to 4 and 5 described above. Although described repeatedly, the remote controller described in the present specification may be referred to as a pointing device.

The pointing device 540 shown in Fig. 5 includes, for example, both an infrared camera and a gyro sensor. In addition, the display device 520 includes at least one sensor 510 capable of sensing an infrared signal emitted from the pointing device 540. It is also within the scope of the present invention that the sensor 510 is implemented by, for example, an IR LED.

Accordingly, the sensor 510 of the display device 520 detects the infrared signal emitted by the pointing device 540, and displays the cursor 530 at the corresponding point. The cursor 530 may be named, for example, as a pointer.

However, a point where the pointing device 540 is directed may not be an area on the screen of the display device 520, and a solution for solving the problem related thereto will be described with reference to FIG.

FIG. 6 is a diagram for explaining a display device that recognizes an orientation point of a pointing device, according to an embodiment of the present invention. FIG. It is also apparent to those skilled in the art that supplementary analysis of Fig. 6 will be apparent to those skilled in the art with reference to Fig.

First, as shown in Fig. 6, the first area is regarded as the absolute coordinate recognition area with respect to the display device, and the second area is regarded as the relative coordinate recognition area. On the other hand, the distinction criterion between the first area and the second area is determined by the sensor of the display device shown in Fig.

For example, when the infrared signal of the pointing device is recognized by three or more infrared LED sensors of the display device, signal processing is performed based on the absolute coordinate system. On the other hand, if this is not the case, signal processing is performed based on the relative coordinate system.

More specifically, for example, when the pointing device moves from the first area to the second area (610), the position of the cursor is changed by the gyro sensor mounted on the pointing device. That is, the position of the cursor is changed regardless of the pointing point of the pointing device.

On the other hand, if the pointing device moves from the second area to the first area (620), the cursor position is changed to the point where the signal of the infrared camera mounted on the pointing device is directed.

However, when the user crosses the first area (absolute coordinate recognition area) and the second area (relative coordinate recognition area) with the pointing device, there is a problem that the cursor is positioned at a point that the user does not intend.

7 is a diagram for explaining a process of correcting a cursor position in consideration of an area to which a pointing point of a pointing device belongs, according to an embodiment of the present invention. For example, when the user changes the point of orientation of the pointing device and the orientation point is sequentially changed to the absolute coordinate recognition area (first area), the relative coordinate recognition area (second area) and the absolute coordinate recognition area (first area) The process of the present invention will be described.

First, as shown in Fig. 7, the locus 710 of the point where the pointing device is directed is divided into a first area (absolute coordinate recognition area), a second area (relative coordinate recognition area) and a first area ). ≪ / RTI >

Particularly, upon entering again from the relative coordinate recognition area to the absolute coordinate recognition area, a process 720 for correcting the position of the cursor is started. For example, since the pointing point of the pointing device is significantly different from the position of the cursor, there is a high possibility that the user recognizes this as an error. In addition, as shown in FIG. 7, when the pointing point of the pointing device enters from the relative coordinate recognition area to the absolute coordinate recognition area, a miss alignment section 730 is likely to occur.

That is, since the user does not know the coordinate recognition area in advance, if there is a considerable difference between the point at which the user points to the pointing device and the position of the cursor on the screen, this causes confusion to the user.

Therefore, according to an embodiment of the present invention, the automatic correction 740 is performed in proportion to the moving speed of the pointing device so that the user can not easily feel the difference.

The cursor is positioned within the screen of the display device and can not escape therefrom. Therefore, when the cursor is moved from the relative coordinate recognition area to the absolute coordinate recognition area, the cursor moves in a state in which a miss alignment phenomenon occurs by an offset distance. At this time, from the cursor position correcting start section 720, the cursor is automatically corrected in proportion to the speed at which the user moves the pointing device so that the pointing device approaches the absolute coordinate pointed by the pointing device.

In the case of such a design, it is possible to minimize the above-mentioned misalignment phenomenon and to solve problems such as bending of the wrist of the user.

In summary, a display device controlled by a pointing device according to an embodiment of the present invention includes a sensor, a controller, a display module, and the like.

The sensor (510 in FIG. 5) is installed in the display device, and at least one or more sensors are located at positions spaced apart from each other.

The controller (106 in FIG. 1) adjusts the position of the pointer so as to correspond to the point of the pointing device, when the pointing point of the pointing device belongs to the first area as a result of sensing the sensor, When the position point to which the device is directed belongs to the second area, the position of the pointer is adjusted based on the motion of the pointing device.

The display module (107 in FIG. 1 or 520 in FIG. 1) outputs a pointer, which is adjusted in position by the controller, to the screen.

The pointing device (310 in FIG. 3, 410 in FIG. 4 or 540 in FIG. 5) includes at least one of a gyro sensor or an infrared camera, for example.

The controller controls the position of the pointer to correspond to a position point pointed by the pointing device in proportion to the moving speed of the pointing device when the pointing point of the pointing device is reentered in the first area And a correction module for correcting the error.

The controller controls the operation of the calculation module to be stopped when the motion of the pointing device is not detected for a preset time.

Wherein the controller is configured to cause the pointing device to move in a predetermined direction after the movement of the pointing device exceeds a predetermined speed and then repeatedly move in a predetermined direction so that when the final position point is included in the first area, Adjust the position of the pointer.

Wherein the controller is configured to determine whether the final position point is included in the second area after the movement of the pointing device exceeds a predetermined speed and simultaneously moves repeatedly in a certain direction, , The position of the pointer is adjusted to a predetermined position value. In this regard, it will be described in more detail with reference to FIG.

8 is a diagram illustrating a first method for implementing the cursor position correction process shown in FIG.

The display device according to an embodiment of the present invention stores the database shown in Fig. 8 in a memory. Therefore, it is possible to read the correction level corresponding to the measured moving speed of the pointing device from the memory, and automatically adjust the position value of the cursor. Although the moving speed is illustrated as one value in FIG. 8, it is also possible to divide the moving speed into a certain section (for example, a first section (A to B), a second section (C to D) Of the right.

9 is a view for explaining a second method for implementing the cursor position correction process shown in Fig.

In contrast to FIG. 8, the equation defined in FIG. 9 is designed so that the position correction value is changed every time according to the moving speed of the cursor. In the case of such a design, there is an advantage that it is not necessary to judge whether the motion speed of the pointing device belongs to which section.

10 is a view for explaining a shaking process according to an embodiment of the present invention. Although it is not necessary for the user to recognize the absolute coordinate recognition area and the relative coordinate recognition area described above, it is necessary to provide a function of resetting the user in some cases. This will be described below with reference to FIG.

When the movement of the pointing device described above exceeds a predetermined speed and simultaneously moves repeatedly in a certain direction and the final position point is included in the first area (absolute coordinate recognition area), the final position pointed by the pointing device Adjust the position of the pointer to correspond to the point.

On the other hand, when the movement of the pointing device described above exceeds a predetermined speed, and the movement of the pointing device repeatedly in a predetermined direction is repeated and the final position point is included in the second area (relative coordinate recognition area) The position of the pointer is adjusted to a predetermined position value (for example, the center of the screen) irrespective of the final position point at which the pointer is positioned.

11 is a flowchart illustrating a method of controlling a display device according to an embodiment of the present invention.

The display device controlled by the pointing device according to the embodiment of the present invention senses the pointing device using at least one sensor installed in the display device (S1110). Further, it is determined whether the point to which the pointing device is directed as a result of sensing the sensor belongs to the area (S1120).

And when the position point that the pointing device is directed to belongs to the first area (absolute coordinate recognition area), the position of the pointer is adjusted to correspond to the pointed point of the pointing device.

On the other hand, when the first area is moved to the second area (relative coordinate recognition area), the position of the pointer is adjusted based on the movement of the pointing device (S1130). For example, step S1130 is implemented using a gyro sensor or the like. Then, the position-adjusted pointer is output on the screen of the display device.

In addition, it is determined whether the pointing point of the pointing device has re-entered the first area in the second area (S1140).

As a result of the determination (S1140), if it is not reentrant, step S1130 is repeated. If it is determined in operation S1140 that the pointer has been reentered, the position of the pointer is corrected to correspond to a point pointed by the pointing device in proportion to the moving speed of the pointing device in operation S1150. This has been described in detail with reference to FIGS. 6 to 9 in this regard.

According to another embodiment of the present invention, if the motion of the pointing device is not detected for a predetermined time, the control unit may control the stopping of the correction step, although not shown in FIG.

11, according to another embodiment of the present invention, after the movement of the pointing device exceeds a predetermined speed and simultaneously moves repeatedly in a predetermined direction, the final position point is moved to the first area And if so, adjusting the position of the pointer to correspond to the last point point at which the pointing device is aimed.

11, according to another embodiment of the present invention, after the movement of the pointing device exceeds a predetermined speed and simultaneously moves repeatedly in a predetermined direction, the final position point is moved to the second area And adjusting the position of the pointer to a predetermined position value, regardless of the final position point at which the pointing device is directed, if included. In this regard, it has been described in detail with reference to FIG.

Therefore, according to the embodiment of the present invention described above, the space pointing method combining the absolute coordinate system and the relative coordinate system is provided to the user, thereby enhancing the intuitiveness at the time of pointing and reducing the problem of wrist bending and the like .
