Abstract

An item selecting apparatus includes a movement detecting unit detecting a movement of a user, a screen displaying image information, a display image storage unit storing data to generate an image to be displayed on the screen, a display image generating unit generating an image to be displayed on the screen, and a control unit controlling so that a plurality of items is displayed on the screen in one of one-, two- and three-dimensional arrangements, in which the control unit receives a signal from the movement detecting unit to measure a movement of the object in at least one of x-, y- and z-axis directions and issues a command to select at least one from among the plurality of items or provides visual feedback thereto, in response to the measured movement of the user and in accordance with the arrangement of the plurality of items on the screen.

Claims

1. An item selecting apparatus comprising:

a movement detecting unit which detects a movement of an object; and

a control unit which controls a plurality of items to be displayed on a screen in one of one-dimensional, two-dimensional and three-dimensional arrangements,

wherein the control unit receives a signal from the movement detecting unit and measures the movement of the object in at least one of x-axis, y-axis and z-axis directions, and

wherein in response to the measured movement, the control unit outputs a command corresponding to one of a selection of at least one of the plurality of items and a visual feedback with respect to the at least one of the plurality of items according to the arrangement of the plurality of items on the screen.

2. The item selecting apparatus of claim 1, wherein,

if the plurality of items is arranged in the one-dimensional arrangement and the movement of the object is within a predetermined angle with respect to a direction of the one-dimensional arrangement, the control unit outputs the command corresponding to the visual feedback with respect to the at least one item, and

wherein if the plurality of items is arranged in the one-dimensional arrangement and the movement of the object is not within the predetermined angle, the control unit outputs the command corresponding to the selection of the at least one item.

3. The item selecting apparatus of claim 2, wherein if changes in the movement of the object are maintained within a predetermined time from a time of outputting the command corresponding to the visual feedback, the control unit outputs the command corresponding to the selection of the at least one item.

4. The item selecting apparatus of claim 2, wherein if the movement of the object corresponds to a predetermined pattern, the control unit outputs the command corresponding to the selection of the at least one item.

5. The item selecting apparatus of claim 1, wherein if the plurality of items is arranged in the two-dimensional arrangement and the movement of the object is in the x-axis and y-axis directions, the control unit outputs the command corresponding to the visual feedback with respect to the at least one item, and

wherein if the plurality of items is arranged in the two-dimensional arrangement and the movement of the object is in the z-axis direction, the control unit outputs the command corresponding to the selection of the at least one item.

6. The item selecting apparatus of claim 5, wherein if changes in the movement of the object are maintained within a predetermined time from a time of outputting the command corresponding to the visual feedback, the control unit outputs the command corresponding to the selection of the at least one item.

7. The item selecting apparatus of claim 5, wherein if the movement of the object corresponds to the predetermined specific pattern, the control unit outputs the command corresponding to the selection of the at least one item.

8. The item selecting apparatus of claim 1, wherein if the plurality of items is arranged in the three-dimensional arrangement, the control unit outputs the command corresponding to the visual feedback with respect to the at least one item in response to the movement of the object,

wherein if changes in the movement of the object are maintained within a predetermined time from a time of the outputting of the command corresponding to the visual feedback, the control unit outputs the command corresponding to the selection of the at least one item and

wherein if the movement of the object corresponds to a predetermined specific pattern, the control unit outputs the command corresponding to the selection of the at least one item.

9. The item selecting apparatus of claim 1, wherein if the measured movement of the object is faster than a predetermined reference speed, the control unit controls the screen to display a second plurality of items, and outputs a second command corresponding to second visual feedback with respect to at least one of the second plurality of items.

10. The item selecting apparatus of claim 1, wherein if the visual feedback is arranged on an edge of the screen and if the measured movement moves toward the edge of the screen, the control unit controls the screen to display a second plurality of items, and the controller outputs a command corresponding to second visual feedback with respect to at least one of the second plurality of items.

11. An item selecting apparatus comprising:

a screen which displays a plurality of items; and

a control unit which displays the plurality of items on the screen in a one-dimensional arrangement,

wherein the control unit measures a movement of an object, and if the movement of the object is within a predetermined angle with respect to an arrangement of the plurality of items, the controller controls the screen to provide visual feedback with respect to at least one item of the plurality of items, and

wherein if the movement of the object deviates from the predetermined angle with respect to the arrangement of the plurality of items, the controller selects the at least one item of the plurality of items.

12. The item selecting apparatus of claim 11, wherein the control unit receives a signal from a movement detecting unit which generates the signal in response to the movement of the object.

13. The item selecting apparatus of claim 12, wherein the movement detecting unit comprises a vision sensor which photographs the object and acquires an image frame.

14. The item selecting apparatus of claim 12, wherein the movement detecting unit comprises a remote controller including at least one of an inertial sensor, a motion sensor, an accelerometer and an optical sensor.

15. A method for selecting at least one item from among a plurality of items displayed on a screen, the method comprising:

displaying a plurality of items on the screen in one of one-dimensional, two-dimensional and three-dimensional arrangements,

detecting a movement of an object; and

measuring the detected movement of the object in at least one of x-axis, y-axis and z-axis directions, and

in response to the measured movement, performing one of issuing a command to select at least one of the plurality of items and providing visual feedback with respect to the at least one of the plurality of items according to an arrangement of the plurality of items on the screen.

16. The method of claim 15, wherein if the plurality of items is arranged in the one-dimensional arrangement, the method further comprises one of:

providing the visual feedback with respect to the at least one item if the movement of the object is measured to be in a direction that falls within a predetermined angle with respect to a direction of arrangement, and

selecting the at least one item if the movement of the object is measured to be in a direction that deviates from the predetermined angle with respect to the direction of arrangement.

17. The method of claim 16, further comprising selecting the at least one item if changes in the movement of the object are maintained within a predetermined time from a time of providing the visual feedback.

18. The method of claim 16, further comprising selecting the at least one item if the movement of the object corresponds to a predetermined specific pattern.

19. The method of claim 15, wherein if the plurality of items is arranged in the two-dimensional arrangement, the method further comprises:

providing the visual feedback with respect to the at least one item if the movement of the object is in the x-axis and the y-axis directions; and

selecting the at least one item if the movement of the object is in z-axis direction.

20. The method of claim 19, further comprising selecting at least one item if changes in the movement of the object are maintained within a predetermined time from a time of providing the visual feedback.

21.
