Therefore, the use satisfaction is improved.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 shows an apparatus for implementing a method for driving a portable terminal using a motion sensor according to the present invention.

An apparatus for implementing a portable terminal driving method using a motion sensor includes a motion sensor 10, a key input unit (including a touch screen) 20 for selecting an operation mode of the portable terminal, and a program for driving the portable terminal. A memory 30 in which various data are recorded, a display 40 for outputting various image data in accordance with an input operation control signal, a speaker 50 for outputting various audio data in accordance with an input operation control signal, and the key Control unit 60 for controlling the operation of the portable terminal according to the signal input from the input unit 20 or the motion sensor 10 and outputs the data to the display 40 and the speaker 50.

In the above-described motion detection sensor 10, a pitch, a roll, and a heading may be detected in addition to the X, Y, and Z-axis movement amount detection.

The key input unit 20 selects whether to use the motion detection sensor 10 together with buttons such as play, stop, fast forward (next, next), rewind (previous, previous), recording, and numbers. The input mode selection key is configured. When the input mode selection key is pressed once, the input mode is selected using the motion detection sensor 10, and when the input mode selection key is pressed again, the input mode using the motion detection sensor 10 is released.

A method of driving a portable terminal using a motion sensor using the device configured as described above will be described below.

First, as shown in FIG. 2, the controller determines whether there is a signal input for selecting an operation mode using a motion sensor from the input mode selection key (S101), and if there is an input mode selection key input, that is, an operation using a motion sensor. If there is a signal input for mode selection, the operation mode of the portable terminal is set to the motion sensor input mode, which will be described in more detail.

The control unit moves the cursor for selecting the operation of the portable terminal to an arbitrary reference point and determines the current position (including direction and angle) of the portable terminal as the reference position (S102) and then outputs a signal output from the motion sensor. In operation S103, when a signal is output from the motion detection sensor, the movement direction and the number or the angle and the number of times are determined. In the input mode using the cursor, the position of the cursor is moved according to the movement direction and the number or the angle and the number. After that (S104), it is determined whether there is an execution-related motion from the motion sensor (S105), and if there is an execution-related motion, the corresponding menu is executed (S106). Return the process.

Then, it is determined whether there is an input mode selection key input for releasing an operation mode selection using the motion sensor (S107), and when there is an input mode selection key input for mode release, the controller switches to the input mode through the key input unit. If there is no input mode selection key input for mode release, the process returns to step S102.

If it is not an input using a cursor, as shown in FIG. 3, when there is a motion sensor output in step S103, the menu is executed by determining a continuous motion direction and the number or the angle and the number of times (S104a). After that, the process is repeated from step S107.

As an example, a case of a media player with the front facing upward while the portable terminal is currently positioned horizontally with respect to the ground will be described as an example.

First, since file selection is required to execute a media player, the controller displays a menu for selecting a file on the display. The menu for selecting a file may be displayed in a list form or a matrix form.

In the case of the matrix form, it can be generally displayed as 3x3, 3x4, etc. In this case, the central portion of the matrix is used as the reference point of the cursor. 4A, the portable terminal is inclined once to the left side or as shown in FIG. 4B. The portable terminal can be rotated at an angle or rotated as shown in FIG. 4C. To move from the center to the menu above, the head of the portable terminal should be moved down once as shown in FIG. 5A or once up as shown in FIG. 5B and the head will be moved up once or down once as shown in FIG. 5B. Will move to the menu below.

And, in order to select the upper left diagonal menu from the center, the portable terminal is moved, rotated or tilted from the center to the left side, and then the head portion is faced down once. The same result can be obtained. The upper right part of the diagonal is to move the portable terminal from the reference position to the right to the right, and then the head part is directed downward once, or the head part is directed downward once and the portable terminal is moved or rotated to the right. After the mobile terminal is moved, rotated or tilted to the left, the head part is faced up once or the head part is faced up once and the mobile device is moved to the left or rotated. After rotating or tilting, the head part is faced up once or the head part is faced up once and then the portable terminal is moved to the right or rotated.

This movement is similarly operated when a play list is output as shown in FIG. 6, numbers are sequentially assigned to the play list, and numbers are displayed in a matrix form below the play list.

That is, in the case of a numeric input in which numbers from 1 to 9 are arranged in a 3x3 form and '0' is separately provided at the bottom, the numbers are arranged on the display and displayed, and the reference point of the cursor is shaded in the drawing. 5 ', the cursor moves to' 4 'when tilted, rotated or moved once from the reference point' 5 'to the left, and when tilted, rotated or moved from' 5 'to the right, the cursor moves to' 6 '. If the head of the portable terminal moves down once at the reference point, the cursor moves to '2', and if the head moves up once, the cursor moves to '8'.

In order to input '1', if the current reference point is '5', the portable terminal moves to the left, rotates, or tilts, and then the head portion is directed down once or the head portion is directed down once, but only after the portable terminal is moved to the left. '3' means that the portable terminal moves to the right from the reference point to the right, or after the portable terminal moves or rotates or tilts, the head is directed down once or the head is directed down once and the mobile terminal moves to the right to the right and then rotates or tilts. '7' means that the portable terminal moves, rotates, or tilts to the left from the reference point, and then the head portion is turned up once or the head is turned up once and then moved to the left, rotated or tilted, and '9' is right from the reference point. The portable terminal moves or rotates Or tilted and then head up once or head up first and then the mobile terminal moves to the right, rotates or tilts. '0' means that the cursor moves from '5' to ' Is moved to 0 '.

On the other hand, since these numbers require continuous input, the control unit judges the signal output from the motion sensor of the portable terminal during the number input process, determines the movement completion position of the cursor, and selects whether to input the corresponding number from the movement completion position. In order to set the reference point and reference position for the input of a new number and to determine the signal for the end of the input, the number input is controlled according to the corresponding signal, and this operation mode is performed through the preset of the portable terminal. After a certain time (t1) has elapsed, the number is input.After the number is entered, the reference point and the reference position are automatically set to the new cursor position and the state of the portable terminal.When the movement is completed, the number of the position is completed. To allow continuous entry of numbers and to clear the selected number. If there is a signal input for a motion related to the clear mode (see FIGS. 8A to 8C below), the corresponding number is deleted.

In addition, when the play list is displayed in a matrix form as shown in FIG. 7 and the four-way direction input display is displayed at the lower part thereof, as shown by shading in FIG. Like the input, the movement of the portable terminal is sensed so that the cursor is moved left / right or up / down.

When the play list is displayed on the display in the form of a list, the control unit places the cursor at a predetermined reference point, such as the top, bottom, or center of the list, and then detects the signal output from the motion sensor and the portable terminal The cursor is moved in the preset direction by determining whether the head moves up or down or whether the head moves up or down.

In this case, when the list has more pages than the number that can be displayed on one screen, when a signal related to a movement for changing the preset list page is input in addition to the movement related to the movement and selection of the cursor, the portable terminal is turned to the left. Move, tilt, or rotate to the previous page. Move, rotate, or tilt to the next page.

In addition, the Clear or Cancel function is required for the numbers selected and displayed on the display in the above-described operation process. In this case, the signal related to the Clear or Cancel motion is set by presetting the motion. If input, the controller executes the command.

For example, as shown in FIGS. 8A to 8C, the portable terminal may be tilted continuously from left to right to left or rotated or moved from left to right to left continuously. .

When there is no movement of the portable terminal for a predetermined time in the moved position, the controller newly sets the state of the moved mobile terminal to the reference position as a reference point and waits for a motion related signal input.

Then, after the setting time has elapsed, the motion related signal of the portable terminal is determined or the motion related signal of the portable terminal immediately after the cursor is moved to execute the corresponding menu or keep the set state continuously. .

For example, in order to execute the menu at the position where the cursor is moved, if there is no signal input related to movement for a predetermined time even after the setting time has elapsed, or if there is a movement signal preset for execution after the cursor is moved, the controller The menu of the portable terminal is executed. More specifically, for example, when the head moves down twice, the menu (number) is input or executed (the selected file is played), or the portable terminal is moved from the reference position and then rereferenced. When restored to a location, the menu can be selected or executed.

In the case of the media player as described above, the operation modes include play, stop, fast forward (next), rewind (previous), recording, and end. In this case, the basic menu selection process is determined as the movement direction / angle and the number of times of the portable terminal in the same manner as the selection of the play list.

Specifically, when the cursor reference point is set as the play menu, and the ending, rewinding (previous), play / stop, fast forward (next), and recording menus are sequentially displayed horizontally from the left, move or rotate to the left in the play mode. Rewind (previous) menu when motion such as tilting is detected, fast forward (next) menu when motion is detected once to the right, exit menu when motion is detected twice to the left, and recording menu when motion is detected twice to the right The cursor may move, and if the portable terminal is restored to a reference position or a signal related to execution is output from the motion sensor after the movement, the corresponding menu may be executed.

As another example, regardless of the position displayed on the display, the play mode of the media player is executed when a play related motion is detected after the play list is selected or when the play related motion is moved in the stop mode, that is, the number of times set up or down. , Fast forward (next) moves twice in succession to the right, Rewind (previous) moves twice in succession to the left, Stop moves up / down once in Run mode, Fast forward (next) or Rewind (previous) mode When the portable terminal is moved at an angle of 90 degrees from the ground, the end of the media player is executed when an operation other than the operation of the motion sensor presented in relation to the media player is detected. For example, the portable terminal may be shaken several times left / right or up / down.

If a signal for releasing the motion sensor input mode is input from the input mode selection key in the above-described operation process, the controller controls the operation of the portable terminal so that the mode is selected using a normal keypad.
