BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: .

In the following description, a detailed description of known technologies related to the present invention will be omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

1 is a diagram illustrating a procedure of a two-dimensional data display method according to a preferred embodiment of the present invention.

As shown in FIG. 1, a two-dimensional data display method according to a preferred embodiment of the present invention displays data stored in a display device on a screen of the display device, and displays data displayed on the screen in accordance with movement of the display device. .

Specifically, the two-dimensional data display method according to the preferred embodiment of the present invention can perform a step of loading data stored in a display device or received from another device (SlOO). The data may be two-dimensional document information or image information composed of pixels.

When the data is loaded, a step of displaying at least a part of the data on the screen of the display device may be performed (S110).

When displaying only a part of the data on the screen of the display device because the number of pixels of the data is larger than the number of fixtures of the screen, the origin is set using the center point between the center point of the data displayed on the screen and the displacement sensor (S120). ≪ / RTI >

FIG. 2 is a view showing a screen of a two-dimensional data display device according to a preferred embodiment of the present invention and a setting of a reference point and a coordinate system on data.

For example, when the display device 10 includes two displacement sensors 12a and 12b as shown in FIG. 2, the pixel of data located at the center point of the data displayed on the screen 13 of the display device 10, It is possible to perform the step of matching the pixels of the screen 13 located at the center of the distance between the two displacement sensors 12a and 12b at one point and setting the point as the origin.

However, the above method is merely an example, and it is possible to set a specific point as the origin through various algorithms or arithmetic expressions.

If the origin is set, the same coordinate system can be set on the screen 13 and the data (s130). More specifically, two displacement sensors having the widest gap among the two or more displacement sensors are selected on the screen (13) and data, a straight line connecting the two displacement sensors is set as a horizontal axis, and a coordinate system Can be set. The interval unit of the coordinate system can be set in pixel units, and it can also be set in actual length unit.

As described above, when the display device 10 has two displacement sensors 12a and 12b as shown in FIG. 2, the straight line connecting the two displacement sensors 12a and 12b is a horizontal axis, The coordinate system can also be set.

The coordinate system may be implemented by any one of an orthogonal coordinate system, a polar coordinate system, a coordinate system in which the above-mentioned coordinate system is mixed, or a complex coordinate system (orthogonal coordinate system in which the horizontal axis is a real number and the vertical axis is an imaginary number).

Particularly, when the coordinate system of the mixed coordinate system is used, the coordinates before and after the displacement of the displacement sensors 12a and 12b can be expressed more accurately.

After setting the origin and the coordinate system on the screen 13 and the data, when the display device 10 is moved in a plane, the coordinates of a new pixel on the screen 13, which is located at the center point between the displacement sensors, A step of recognizing the rotation angle of the rotation shaft 10 may be performed (s140).

That is, assuming that the coordinate system set on the screen and the data is a two-dimensional coordinate system, when the user moves the display device 10 in a plane, the display device 10 It is possible to measure the moving distance and rotation angle.

More specifically, when the display device 10 moves in a plane, a change in the position of the displacement sensor itself can be detected through the displacement sensor. Thus, it is possible to know the coordinates of the point where the displacement sensor is located in the set coordinate system. When the center point between the coordinates is calculated, the coordinates of the new pixel of the screen 13 located at the center point can be recognized.

A straight line connecting the two displacement sensors having the largest gap among the plurality of displacement sensors described above is compared with a straight line connecting the coordinates of the point where the two displacement sensors are located after the display device 10 moves, Can be measured.

Particularly, in the display device 10, two displacement sensors 12a and 12b are mounted on both ends of the display device 10, and in the embodiment in which the screen 13 and the coordinate system set on the data are orthogonal coordinate systems , As shown in FIG. 3, the movement of the display device 10 can be recognized by dividing the movement into 'coordinate movement' and 'axis rotation movement'.

In the range of

Can be calculated through the equation. Accordingly, the display device 10 is rotated in the axis by 0 degrees in the orthogonal coordinate system.

When the step of recognizing the coordinates of the new pixel on the screen 13 and the rotation angle of the display device 10 is performed, the display device 10 displays the coordinates of the new pixel on the screen 13, And displaying the rotated data on the screen with the center of the pixel located at the center of the screen and rotated by the rotation angle in a direction opposite to the display device 10 in operation S150.

에 위치한 픽셀을 중심점으로 하고, 종래 화면(13)에 표시되는 것에서 -θ만큼 회전시킨 데이터를 화면(13)에 표시하는 단계를 수행할 수 있다. That is, on the basis of the above-mentioned example, the coordinates of the new pixel on the screen 13 are

, And the rotation angle of the display device 10 may be?. At this time, the display device 10

And the coordinates

And displaying on the screen 13 data rotated by -θ from that displayed on the conventional screen 13 by using the pixel positioned at the center as the center point.

Since the screen 13 and the data are set in the same coordinate system, the data on the data can be displayed on the screen 13 rotated by -θ with respect to the same horizontal axis (a straight line connecting the two displacement sensors).

Meanwhile, the two-dimensional data display method according to another embodiment of the present invention may further include repeating steps S120 through S150.

That is, the display device 10 moved to the new position resets the new origin and the coordinate system. Then, the display device 10 recognizes the movement of the display device 10 through the displacement sensor, and displays the changed data on the screen 13 accordingly.

If the display device 10 repeats the above steps and moves spatially instead of in a plane, the origin and the coordinate system are not reset. If the data displayed on the screen of the display device is fixed before the display device 10 moves And may not change.

The displacement sensor of the display device 10 can also measure changes in the upward and downward movements of the display device so that when the upward and downward movements of the display device 10 are measured, The data is fixed to the data displayed on the screen 13 before the display device 10 is moved.

By the above operation, the user can observe the whole data in detail while moving the display device 10, for example, on the desk while moving it. If the user finds a data area he / she wants to continuously observe When the user does not want the data to change any more, the user can move the display device 10 spatially and fix the data of the desired area on the screen.

Meanwhile, in the two-dimensional data display method according to another embodiment of the present invention, the size of data displayed on the screen 130 of the display device 10 is set by matching the pixels of the screen with the pixels of the data by a predetermined multiple The method comprising the steps of:

As mentioned above, the data may be two-dimensional document information or image information composed of pixels.

There may be a case where the number of pixels of the data and the number of pixels of the screen 13 of the display device 10 are not equal to each other. At this time, the size of the data displayed on the screen 13 of the display device 10 can be set by matching pixels of the screen 13 with pixels of the data at a predetermined multiple.

For example, one pixel of data per pixel of the screen may be matched, or one pixel of data per four pixels of the screen may be matched, provided that the number of pixels of data is greater than the number of pixels of the screen. In this case, only some data among the entire data can be displayed on the screen.

A multiple of the pixel can be adjusted through the user's input to the display device 10. [

That is, the user can increase the number of pixels of the screen, which is matched per pixel of the data, to a predetermined multiple by accumulating and spreading two fingers while maintaining the touch state on the screen 13 of the display device 10. In addition, the number of pixels of the screen that are matched per pixel of data can be reduced to a predetermined multiple by spreading and collecting two fingers touched on the screen 13.

The operation principle of the technique for adjusting the drainage amount according to the touch input is obvious to a person skilled in the art and a detailed description thereof will be omitted.

On the other hand, when the display device 10 moves in a plane and crosses the boundary of data, it may be a problem how to display an area outside the boundary between data and data on the screen.

In order to overcome the above-described problems, a two-dimensional data display method according to a preferred embodiment of the present invention is characterized in that, as shown in FIG. 6, when the display device 10 moves in a plane and reaches the boundary of data, May be displayed as a black image or nothing on the screen.

If the ratio of the area outside the borderline on the screen exceeds a threshold value (for example, 50%), the data displayed on the screen or the area outside the borderline are fixed and displayed in a state before the display device 10 moves .

On the contrary, if the ratio of the area outside the borderline is lower than the threshold value, the data displayed on the screen may be changed according to the movement of the display device 10.

Further, in order to increase the resolution of the optical sensor, the display device 10 preferably moves in a flat state in contact with the ground.

The screen 13 according to the preferred embodiment of the present invention may display at least a part of the data.

For example, if the number of pixels of the data is larger than the number of pixels of the screen 13, the screen 13 of the display device 10 is displayed on the screen 13 under the assumption that the pixels of the data and the pixels of the screen 13 match one- You will only see some areas. The shape of the screen 13 may be a polygonal shape including a circle, a triangle, and a square.
