Abstract

A slidable input device and a portable apparatus including the same, in which objects arranged in three-dimension or the size of a specific object can be easily manipulated and controlled. The portable apparatus includes an input unit for generating a key-selection signal corresponding to up, down, right or left directions selected by a user and a movement signal corresponding to a direction to which the input unit is moved by the user through an external force; a signal input unit for receiving the key selection signal and the movement signal generated by the input unit; a control unit for carrying out a predetermined operation indicated by the key selection signal and the movement signal inputted by the signal input unit; and a display unit for displaying the object according to the predetermined operation on a screen.

Claims

1. An input device comprising:

a direction key which is operable to move an object image which is displayed on a display screen, in one of a horizontal direction and a vertical direction;

a sliding unit which slidably moves the direction key one of vertically and horizontally in response to an external force to cause the object image to move in one of a first direction and a second direction which are different than the horizontal direction and the vertical direction; and

a returning unit which returns the direction key to its initial position through a repulsive force.

2. The input device of claim 1, wherein if the direction key is slidably moved in a first horizontal or vertical direction, the object image is moved in the first direction which is normal to a plane formed by a vertical axis and a horizontal axis of the object, and if the direction key is slidably moved in a second horizontal or vertical direction opposite to the first horizontal or vertical direction, the object image is moved in the second direction, which is opposite to the third direction and is normal to the plane formed by the vertical axis and horizontal axis.

3. The input device of claim 1, wherein if the direction key is slidably moved horizontally or vertically, the object image is zoomed in or zoomed out.

4. An apparatus comprising:

an input unit which generates a key selection signal corresponding to one of a horizontal direction and a vertical direction, and generates a movement signal corresponding to one of a first direction and a second direction in which the input unit is moved by an external force; and

a control unit which performs an operation based on the key selection signal and the movement signal generated by the input unit; and

a display unit which displays an object according to the operation performed by the control unit.

5. The apparatus of claim 4 further comprising:

a searching unit which searches a key code value and a movement code value respectively corresponding to the key selection signal, and the movement signal generated by the input unit; and

a memory which stores the key code value and the moving code value corresponding to the key selection signal and the movement signal generated by the input unit, together with operation commands assigned to the key code value and the moving code value.

6. The apparatus of claim 4, wherein if the input unit is moved in the first direction, a movement signal corresponding to movement of the object in a third direction, which is normal to a plane formed by a vertical axis and a horizontal axis of the object, is generated, and if the input unit is moved in the second direction, which is opposite to the first direction, a movement signal corresponding to movement of the object in a fourth direction, which is normal to the plane formed by the vertical axis and the horizontal axis of the object and is opposite to the third direction, is generated.

7. The apparatus of claim 4, wherein a zoom-in key signal is generated if the input unit is moved in the first direction, and a zoom-out key signal is generated if the input unit is moved in the second direction which is opposite to the first direction.

8. The apparatus of claim 4, wherein the input unit returns to an initial position, after having been moved to one of the first and second positions, through a repulsive force.

9. An apparatus comprising:

an input unit which generates a key selection signal corresponding to one of a horizontal direction and a vertical direction, or generates a movement signal corresponding to one of a first direction and a second direction in which the input unit is moved, in order to select and control an object; and

a display screen which displays the object according to the key selection signal or the movement signal generated by the input unit.

10. The apparatus of claim 9, wherein the input unit comprises:

a direction key which generates the key selection signal to move the object in a direction corresponding to one of the horizontal direction and the vertical direction and generates the moving signal to move the object in a direction corresponding to one of the first direction and the second direction in which the direction key is moved;

a sliding unit which enables the direction key to be moved in the first direction and the second direction; and

a returning unit which enables the direction key to be returned to an initial position through a repulsive force.

11. The apparatus of claim 9, wherein if the input unit is moved in the first direction, a movement signal corresponding to movement of the object in a third direction which is normal to a plane formed by a vertical axis and a horizontal axis of the object, is generated, and if the input unit is moved in the second direction, which is opposite to the first direction, a movement signal corresponding to movement of the object in a fourth direction, which is normal to the plane formed by the vertical axis and the horizontal axis of the object and is opposite to the third direction, is generated.

12. The apparatus of claim 9, wherein a zoom-in key signal is generated if the direction key is moved in the first direction, and a zoom-out key signal is generated if the direction key is moved to the second direction which is opposite in the first direction.
