In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Further, the electronic device 20 may be provided with a device capable of connecting to the Internet 40 by TCP / IP (Transmission Control Protocol / Internet Protocol).

2A is a diagram showing an example of the appearance of a 3D pointing device 10 according to an embodiment of the present invention. 2B is a block diagram of a 3D pointing device 10 according to an embodiment of the present invention. Referring to FIGS. 2A and 2B, a 3D pointing device 10 according to an embodiment of the present invention will be described in detail.

The 3D acceleration sensor 101 is a sensor for acquiring tilt information of the 3D pointing device 10.

The tilt information according to the present invention may include acceleration information sensed by the 3D acceleration sensor 101 and tilt angle of the 3D pointing device 10 obtained by the sensed acceleration information (1) and (2) may be used). The inclination information may further include a tilting speed of the 3D pointing device 10, as described later.

The 3D acceleration sensor 101 can sense acceleration in three axial directions applied to the 3D pointing device 10.

Earth gravity is gravitational acceleration 1g in the vertical direction, and when the horizontal acceleration sensor tilts, 90g in response to gravity, that is, 1g when vertical is detected.

Hereinafter, a method for generating pointer control information using a 3D pointing device according to embodiments of the present invention, a pointer control method for an electronic device, and a 3D pointing device 10 and an electronic device 20 will be described in detail.

5 is a flowchart of a method of generating pointer control information using a 3D pointing device according to the first embodiment of the present invention. The method of generating pointer control information using the 3D pointing device according to the first embodiment of the present invention can be implemented in the 3D pointing device 10 described above with reference to Figs. Hereinafter, a method of generating pointer control information using the 3D pointing device according to the first embodiment of the present invention and an operation of the 3D pointing device 10 for implementing the pointer control information will be described in detail with reference to FIG. 5 and necessary drawings.

The control unit 105 enters a tilt sensing mode for sensing the tilt of the 3D pointing device 10 (S100). The step S100 may be performed, for example, by an operation of the user with respect to the 3D pointing device 10. The 3D pointing device 10 may include a separate key button for entering the tilt sensing mode. When the user presses the separate key button, the 3D pointing device 10 enters the tilt sensing mode, and the 3D pointing device 10 can recognize the inclination of the 3D pointing device 10. [

The controller 105 acquires acceleration values for the three axes of the 3D pointing device 10 using the 3D acceleration sensor 101 (S110).

The control unit 105 removes noise from the obtained three-axis acceleration values (S120). The obtained three-axis acceleration values may include noise generated by the hand tremor of the user or the sensor itself. In step S120, such noise is removed.

In step S120, various adeptive filters may be used to remove noise. For example, filters such as Weighted Fourier Linear Combiner (WFLC), Dynamic Frequency Adjustment, and Kalman Filter may be used.

The WFLC may be used to remove noise due to different shakes according to the user, and the Dynamic Frequency Adjustment may be applied to the data of the data output from the 3D pointing device 10 according to the moving speed of the pointer The filtering effect can be obtained by adjusting the output frequency.

The control unit 105 obtains the tilt information of the 3D pointing device 10 using the three-axis acceleration values from which the noise is removed (S130).

The inclination information includes a tilt angle. The tilt angle may include a roll angle and a pitch angle. The roll angle and the pitch angle can be obtained by the above-described equations (1) and (2).

The inclination information obtained in step S130 may include the tilting speed of the 3D pointing device 10. [

The control unit 105 may consider the screen resolution of the electronic device 20 which is a target device to which the 3D pointing device 10 transmits a signal, Dimensional movement information of the pointer displayed on the screen of the electronic device 20 by mapping the angle to the screen of the electronic device 20 (S140).

6 is a diagram showing an example of mapping a tilt angle to a screen of an electronic apparatus. Referring to FIG. 6, the roll angle is mapped to a horizontal direction (x axis) of the screen, and the pitch angle may be mapped to a vertical direction (y axis) of the screen.

For example, in FIG. 6, the point F indicates a state (the roll angle = 0, the pitch angle = 0) in which the 3D pointing device 10 lies horizontally with respect to the ground surface. When the 3D pointing device 10 rotates 20 degrees in the x-axis direction (about the y-axis) in a state corresponding to point F, the display 203 of the electronic device 20 corresponds to the point a . When the 3D pointing device 10 rotates by -30 degrees in the y axis direction (about the x axis) in the state corresponding to the point F, it can correspond to point d in the display 203. [ In this way, the rotational positions B and C of the 3D pointing device can correspond to the points b and c of the display 203, respectively. If the 3D pointing device 10 rotates 20 degrees in the x axis direction and rotates 30 degrees in the y axis direction in a state corresponding to the point F, the display 203 may correspond to the point e.

The corresponding relationship between the tilt angle of the 3D pointing device 10 and the point on the display 203 can be defined by a predetermined scaling factor or mapping coefficient. The scaling factor or the mapping coefficient may be determined in consideration of the resolution of the display 203. Also, the scaling factor or the mapping coefficient may be determined by the user. For example, in general, a user may predetermine an angle at which the 3D pointing device 10 can be tilted to the maximum, and the maximum tilt angle may be associated with the edge of the display 203. [ Fig. 6 shows a case in which the maximum angle of the roll angle is set to 45 degrees horizontally, and the maximum angle of the pitch angle is set to 50 degrees vertically. Assuming that the horizontal resolution of the screen of the electronic device 20 is 1366 pixels, in the case of FIG. 6, about 15 pixels (= 1366/90) corresponds to 1 degree of roll angle.

The corresponding relationship between the tilt angle of the 3D pointing device 10 and the point on the display 203 can be defined by a dynamically changeable scaling factor or mapping factor. The control unit 105 may recognize the shaking of the 3D pointing device 10 using the tilt information and may automatically correct the scaling factor or the mapping coefficient in consideration of the shaking. For example, when the 3D pointing device 10 detects a degree of camera shake during the recent movement of the 3D pointing device 10, the control unit 105 determines whether the 3D pointing device 10 is in a specific posture (for example, Is 0), the scaling factor may be updated by reflecting the degree of the shaking motion.

In contrast to FIG. 6, the roll angle is mapped to the vertical direction (Y axis) of the screen, and the pitch angle may be mapped to the horizontal direction (X axis) of the screen.

The control unit 105 can generate the two-dimensional movement information that the pointer will move on the display 203, using the correspondence described with reference to Fig. The two-dimensional movement information may be a coordinate of a target point at which the pointer moves. The two-dimensional movement information may be a movement distance and a movement direction in which the pointer should move. The coordinates and the moving distance may be represented by pixels.

The control unit 105 generates control information of the pointer (S150). The control information of the pointer may include the two-dimensional movement information generated in step S140.

The control unit 105 transmits the control information of the pointer generated in step S150 to the electronic device 20 through the communication unit 104. [

The control information of the received pointer may include two-dimensional movement information obtained by the tilt angle of the 3D pointing device 10. In step S180, the controller 207 moves the pointer according to the two-dimensional movement information.

FIG. 8D shows a case where a non-zero roll angle and a non-zero pitch angle occur by simultaneously tilting the 3D pointing device 10 in the x-axis direction and the y-axis direction. 8D, the pointer 50 moves diagonally on the display 203 because the 3D pointing device 10 simultaneously generates a non-zero roll angle and a non-zero pitch angle.

When the user tilts the 3D pointing device 10 once at a speed greater than or equal to the predetermined value in the Y-axis direction (about the X-axis), the object 60 currently pointed to by the pointer 50 may be selected (Object selection function). At this time, a change with respect to the pointer 50 does not occur. When the user tilts the 3D pointing device 10 at a speed equal to or greater than a predetermined value at least two times within a predetermined time, the object 60 currently pointed to by the pointer 50 can be executed (object executing function). At this time, the pointer 50 does not change.

The user can set various functions that can be executed in step S330. For example, when the 3D pointing device 10 is tilted once in the X-axis direction, it can be configured to perform an internet connection function. For example, if the 3D pointing device 10 is tilted twice in the X-axis direction, a user interface screen for image quality adjustment may be displayed.

13 is a flowchart of a method for executing functions of an electronic device according to the sixth embodiment of the present invention. A method for executing functions of the electronic device according to the sixth embodiment of the present invention can be implemented in the electronic device 20 described above with reference to Figs. Hereinafter, with reference to FIG. 13, a method for executing functions of the electronic device according to the sixth embodiment of the present invention and an operation of the electronic device 20 for implementing the function will be described in detail.

The control unit 207 of the electronic device 20 receives tilt information including the tilt angle and the tilt velocity of the 3D pointing device 10 from the 3D pointing device 10 through the communication unit 201 S400].

The controller 207 determines whether the inclination speed included in the received tilt information is less than or equal to a predetermined threshold (S410).

If the tilting speed is less than the predetermined value as a result of the determination in step S410, the controller 207 controls the display unit 203 to display the two-dimensional movement information of the pointer displayed on the display 203 in the same manner as in the fourth embodiment of the present invention And generates pointer control information that includes [S420]. The two-dimensional movement information of the pointer can be obtained using the received tilt angle.

The controller 207 controls the pointer according to the generated pointer control information (S430). For example, the controller 207 moves the pointer displayed on the display 203 according to the two-dimensional movement information of the pointer.

If the inclination speed is not equal to or less than the predetermined value, the controller 207 performs another predetermined function without performing a pointer control function such as moving the pointer (S440) . The step S440 is the same as the step S330 of the fifth embodiment of the present invention described above.

According to embodiments of the pointer control of the embodiments of the present invention described above, the pointers displayed on the screen of the electronic device 20 can be controlled using only the tilt information of the 3D pointing device 10. According to the embodiments of the present invention, absolute coordinate-based pointer control is possible. 14 is a diagram for explaining absolute coordinate-based pointer control.

According to the absolute coordinate-based pointer control, the position of the pointer displayed on the screen is matched to the attitude (tilt angle) of the 3D pointing device 10 with respect to the surface of the earth. The matching relationship between the specific posture of the 3D pointing device 10 and the specific position of the pointer is a one-to-one (1: 1) correspondence. That is, the state where the 3D pointing device 10 is tilted at a specific tilt angle means that the pointer is located at a specific point corresponding to the specific tilt angle on the screen. The 3D pointing device 10 acquires acceleration values for three axes on the basis of gravitational acceleration applied to the 3D pointing device 10 using the 3D acceleration sensor 101, Since it is used for mapping, absolute coordinate-based pointer control is possible.

For example, in FIG. 14, the corresponding relationship between the M, N and L points on the display 203 and the 3D pointing device 10 posture is shown in Table 1 below.

The position on the display 203 The orientation of the 3D pointing device 10
Roll Angle (°) Pitch Angle (°) M point 0 0 N point -α 0 Point L -α beta

An M point on the display 203 corresponds to a state in which the orientation of the 3D pointing device 10 is parallel to both the X axis and the Y axis with respect to the ground surface. The N point corresponds to an attitude in which the 3D pointing device 10 forms a roll angle of -α degrees with respect to the ground surface with respect to the X axis. The L point corresponds to an attitude in which the 3D pointing device 10 forms a roll angle of -α ° with respect to the X-axis with respect to the ground surface, and forms a pitch angle of β ° with respect to the Y-axis.

The operation of the user to operate the 3D pointing device 10 to control the pointer 50 on the display 203 will be described below.

If the user keeps the 3D pointing device 10 parallel to the ground surface, the pointer 50 is located at point M (S10).

As the user tilts the 3D pointing device 10 to the right while maintaining parallelism with respect to the surface-Y axis, the pointer 50 moves toward the N point. If the user keeps the 3D pointing device 10 tilted by -α ° with respect to the ground surface-parallel to the Y-axis and with respect to the surface-X-axis, the pointer 50 is located at the N-point (S11).

As the user tilts the head of the 3D pointing device 10 toward the sky while maintaining the state in which the 3D pointing device 10 is inclined by -α ° with respect to the ground surface -X axis in the state S11, The pointer 50 moves toward the L point. When the user tilts the 3D pointing device 10 by? ° with respect to the ground surface-Y axis and tilts by -α ° with respect to the surface-X axis, the pointer 50 is located at point L (S12) .

When the user operates the 3D pointing device 10 such that the 3D pointing device 10 is parallel to the X and Y axes with respect to the ground surface in the state S12, the pointer 50 returns to point M [S10].

As described above, according to the embodiments of the present invention, since the specific position or the specific posture of the 3D pointing device 10 is mapped to a specific point on the screen of the electronic device 20, It is possible.

FIG. The rotation about the X axis corresponds to the pitch operation, and the rotation about the Z axis corresponds to the yaw operation.

For example, by using the two-axis gyro sensor, angular velocity information on the pitch operation and angular velocity information on the yaw motion can be obtained. The relative movement distances dX and dY of the pointer displayed on the display 803 of the electronic device 80 described later can be obtained by using the angular velocity information about the two axes.

Hereinafter, with reference to FIG. 18 and necessary drawings, a method of generating pointer control information using a 3D pointing device according to a seventh embodiment of the present invention and an operation of a 3D pointing device 70 for implementing the method will be described in detail.

The controller 706 enters a motion detection mode for detecting the motion of the 3D pointing device 70 (S500). The step S500 may be performed by a user's operation on the 3D pointing device 70, as in the first embodiment of the present invention. Also, the step S500 may be performed by receiving a signal from the electronic device 80 through the communication unit 704 to enter the motion detection mode.

The control unit 706 receives a selection signal for selecting at least one of the 3D acceleration sensor 701 and the gyro sensor 702 (S510). The selection signal may be received from the electronic device 80 through the communication unit 704. [ The selection signal may be input from a user. For example, the user can operate the key button unit 703 to select the 3D acceleration sensor 701 and / or the gyro sensor 702. For example, the 3D acceleration sensor 701, the gyro sensor 702, the 3D acceleration sensor 701, and the 3D acceleration sensor 701 are selected by the user whenever a user presses a specific toggle key provided on the key button unit 703. [ And the gyro sensor 702 can be sequentially selected (toggling method).

The controller 706 may deactivate the sensor not selected by the selection signal among the 3D acceleration sensor 701 and the gyro sensor 702. [ The inactivation will be described in detail in an eighth embodiment of the present invention which will be described later.

The control unit 706 acquires at least one of the tilt information of the 3D pointing device 70 and the angular velocity information of the 3D pointing device 70 according to the selection signal received in step S510. The tilt information is acquired using the 3D acceleration sensor 701, and the angular velocity information can be acquired using the gyro sensor 702. [ The angular velocity information may include a pitch operation and an angular velocity with respect to the yaw operation. Step S520 is the same as or similar to that described in detail in the first to sixth embodiments of the present invention described above.

The control unit 706 transmits the at least one piece of information obtained in step S520 to the electronic device 80 through the communication unit 704 (S530). For example, if the gyro sensor 702 is selected in step S510, the controller 706 transmits the angular velocity information obtained in step S520 to the electronic device 80. [ If both the 3D acceleration sensor 701 and the gyro sensor 702 are selected in step S510, the controller 706 determines whether the gyro information and the angular velocity information obtained in step S520 To the electronic device (80).

19 is a flowchart of a method of generating pointer control information using a 3D pointing device according to an eighth embodiment of the present invention. The method of generating pointer control information using the 3D pointing device according to the eighth embodiment of the present invention can be implemented in the 3D pointing device 70 described above with reference to FIGS. 15 and 16. FIG. The method of generating pointer control information using the 3D pointing device according to the eighth embodiment of the present invention and the operation of the 3D pointing device 70 for implementing the method will be described in detail with reference to FIG.

The controller 706 enters a motion detection mode for detecting the motion of the 3D pointing device 70 (S550). The step S550 is the same as the step S500 of the seventh embodiment of the present invention.

The control unit 706 receives a selection signal for selecting any one of the 3D acceleration sensor 701 and the gyro sensor 702 (S551). The step S551 is similar to or similar to the step S510 of the seventh embodiment of the present invention.

The control unit 706 activates one of the 3D acceleration sensor 701 and the gyro sensor 702 according to the selection signal received in step S551 and deactivates the other one [S552, S553, S555] . For example, the controller 706 determines whether the selection signal is a signal that selects the 3D acceleration sensor 701 (S552). If it is determined in step S552 that the 3D acceleration sensor 701 is selected, the 3D acceleration sensor 701 is activated and the gyro sensor 702 is deactivated. If it is determined in step S552 that the selection signal is a signal that selects the gyro sensor 702, the 3D acceleration sensor 701 is deactivated and the gyro sensor 702 is activated. The deactivation includes an operation of turning off the sensor. The power consumption can be reduced by deactivation of the 3D acceleration sensor 701 or the gyro sensor 702.

20 is a flowchart of a pointer control method of an electronic device according to a ninth embodiment of the present invention. The pointer control method of an electronic device according to the ninth embodiment of the present invention corresponds to a method of generating pointer control information using the 3D pointing device according to the seventh or eighth embodiment of the present invention described above. The pointer control method of the electronic device according to the ninth embodiment of the present invention can be implemented in the electronic device 80 described above with reference to Fig. Hereinafter, with reference to FIG. 20 and necessary drawings, a method of controlling a pointer of an electronic device according to a ninth embodiment of the present invention and an operation of the electronic device 80 for implementing the method will be described in detail.

The control unit 807 of the electronic device 80 transmits a selection signal for selecting at least one of the 3D acceleration sensor 701 and the gyro sensor 702 to the 3D pointing device 70 through the communication unit 801, (S600). The selection signal is used to determine whether to control the pointer displayed on the display 803 by using any of the tilt information acquired by the 3D acceleration sensor 701 and the angular velocity information acquired by the gyro sensor 702 . The controller 807 can use either the tilt information or the angular velocity information or control the pointer using both the tilt information and the angular velocity information as described later.

Generally, in the case of controlling the pointer by mapping the angular velocity values obtained by the gyro sensor 702 to the display 803, more precise control is possible than when the 3D acceleration sensor 701 alone is used. 21A and 21B are diagrams for comparing the pointer control using the acceleration sensor and the pointer control using the gyro sensor.

According to the absolute coordinate-based pointer control method using the 3D acceleration sensor, as described above, the inclination angles within the range of the predetermined roll angle and pitch angle are matched at 1: 1 on the screen. 21A shows absolute coordinate-based pointer control using a 3D acceleration sensor. For example, referring to FIG. 21A, when the predetermined point of the pitch angle is 2a, when the 3D pointing device 70 moves by a pitch angle of 1 DEG, the pointer 50 moves by n / 2a pixels .

FIG. 21B shows pointer control based on relative coordinates using a gyro sensor. For example, referring to FIG. 21B, the output value b of the gyro sensor can be associated with the moving amount n 'pixel of the pointer 50. Since yaw and pitch movements of the 3D pointing device 70 using the gyro sensor have a wide range of motion, in the pointer control based on the relative coordinates using the gyro sensor, As the movement amount n 'of the pointer 50 is reduced, the amount of movement of the pointer 50 with respect to the same movement of the 3D pointing device 70 becomes smaller, and precise control becomes possible.

The present invention proposes a method of selectively using at least one of the tilt information and the angular velocity information to control the pointer according to various contexts. 22 is a diagram for explaining a situation of controlling a pointer using angular velocity information.

The controller 807 may select at least one of the 3D acceleration sensor 701 and the gyro sensor 702 according to the type of the information displayed on the display 803. [

For example, FIG. 22 shows a case where the electronic device 80 is connected to the Internet. A web page provided by a web site generally provides a lot of information on one screen at the same time. The user needs to precisely control the pointer 50 in order to access specific information among a large amount of information displayed on the screen. When the electronic device 80 is connected to the Internet and displays web information on the display 803 as shown in FIG. 22, since the pointer 50 needs to be precisely controlled, the controller 807 controls the gyro sensor 702, or both of the 3D acceleration sensor 701 and the gyro sensor 702 can be selected.

When the electronic device 80 receives a broadcast signal from the broadcast station 30 and displays the video information included in the broadcast signal on the display 803, simple and quick control over the precise control of the pointer 50 Therefore, the controller 807 can select only the 3D acceleration sensor 701.

The control unit 807 receives at least one of the tilt information and the angular velocity information of the 3D pointing device 70 from the 3D pointing device 70 through the communication unit 801 at operation S610. The 3D pointing device 70 transmits at least one of the tilt information and the angular velocity information to the electronic device 80 according to the selection signal transmitted in step S600.

The control unit 807 generates two-dimensional movement information of the pointer 50 using at least one piece of information received in step S610 (S620), and displays the two-dimensional movement information on the display 803 The pointer 50 is moved (S630). The two-dimensional movement information can be generated in the same or similar manner as in the above-described first to sixth embodiments. However, the case of generating the two-dimensional movement information using both the tilt information and the angular velocity information will be described in detail as follows.

The angular velocity information obtained by the gyro sensor 702 is corrected by the tilt information, and the corrected angular velocity information is matched to the display 803, so that the two-dimensional movement information can be generated.

When the 3D pointing device 70 is horizontally moved in a tilted state (for example, the roll angle is not 0), only the angular velocity information is matched to the display 803 to generate the two-dimensional movement information The pointer 50 may move diagonally rather than horizontally. This leads to deterioration of the usability in terms of the user, so correction using the inclination information is necessary.

The tilt information may correct the angular velocity information. The following equation (3) is an example of an equation used for correcting the angular velocity information.

Here, φ is the roll angle is obtained by the equation (1), and (X _G, Y _G) is an angular velocity before correction, (X _A, Y _A) is the angular velocity after correction, a matrix R is Rotation Matrix. The control unit 807 can generate the two-dimensional movement information by mapping the corrected angular velocity X _A , Y _A to the display 803.

23 is a flowchart of a method of generating pointer control information using a 3D pointing device according to a tenth embodiment of the present invention. The method of generating pointer control information using the 3D pointing device according to the tenth embodiment of the present invention can be implemented in the 3D pointing device 70 described above with reference to FIGS. Hereinafter, with reference to FIG. 23 and necessary drawings, a method of generating pointer control information using a 3D pointing device according to a tenth embodiment of the present invention and an operation of a 3D pointing device 70 for implementing the method will be described in detail.

The controller 706 enters a motion detection mode for sensing the motion of the 3D pointing device 70 (S700). The step S700 is the same as the step S500.

The control unit 706 acquires the tilt information of the 3D pointing device 70 using the 3D acceleration sensor 701 and then outputs the tilt information of the 3D pointing device 70 to the 3D pointing device 70 using the gyro sensor 702. [ Is acquired [S720]. Steps S710 and S720 are the same as steps S520 and S530, respectively.

The control unit 706 transmits both the acquired tilt information and the angular velocity information to the electronic device 80 through the communication unit 704 (S730).

The control unit 807 generates two-dimensional movement information of the pointer 50 using one of the tilt information and the angular velocity information [S810], and displays the pointer 803 on the display 803 in accordance with the two- (Step S820). In step S810, which of the tilt information and the angular velocity information is used is the same as that described in the ninth embodiment of the present invention. For example, the controller 807 selects one of the tilt information and the angular velocity information in consideration of the type of information displayed on the display 803, and uses the selected information to calculate the two-dimensional Movement information can be generated. Also, for example, the control unit 807 may calculate the inclination information and the angular velocity information in consideration of the type of the information currently indicated by the pointer 50 or the type of the area where the pointer 50 is currently located You can also select one piece of information.

The pointer referred to in the present invention does not mean only the graphics in the form of arrows shown in FIG. 14 or the other drawings. Pointers referred to in the present invention may include various types of indicators. 25 is a diagram showing an example in which a pointer is displayed in a different type of graphic. The pointer 50 shown in Fig. 25 may be a graphic in which the icon is highlighted or a graphic indicating that the current icon has been selected, such as a thick border.

In FIG. 25, in step S900, when a roll angle occurs by tilting the 3D pointing device 10, 70 according to various embodiments of the present invention in the X-axis direction (about the Y-axis) [S910] The controller 50 moves to select the icon to the right of the icon selected in step S900 (S920). If the pitch angle is generated by the user tilting the 3D pointing device 10, 70 in the Y axis direction (about the X axis) in step S900, the pointer 50 moves, and in step S900 The icon at the bottom of the selected icon is selected (S940). When the user simultaneously tilts the 3D pointing device 10, 70 in the X and Y axis directions in step S900, if both the roll angle and the pitch angle are generated (S950), the pointer 50 moves and the S900 The icon in the diagonal direction of the icon selected in step S960 is selected.
