Abstract

Disclosed is an apparatus and method of providing feedback of a location of a cursor in a tilt-based list search. An apparatus for providing feedback of a location of a cursor in a tilt-based list search according to an aspect of the present invention includes a cursor location control module calculating and changing the location of the cursor according to a tilt angle, a probability calculating module calculating probabilities of the cursor being located at items of each list according to the calculated location of the cursor, and a display module changing an attribute of the list according to the calculated probabilities and displaying the list.

Claims

1. An apparatus for providing feedback of a location of a cursor in a tilt-based list search, the apparatus comprising:

a cursor location control module calculating and changing the location of the cursor according to a tilt angle;

a probability calculating module calculating probabilities of the cursor being located at items of each list according to the calculated location of the cursor; and

a display module changing an attribute of the list according to the calculated probabilities and displaying the list.

2. The apparatus of claim 1, further comprising:

a tilt angle calculating module calculating the tilt angle.

3. The apparatus of claim 1, wherein the cursor location control module changes the location of the cursor according to a tilt angle and a tilt direction of a portable apparatus.

4. The apparatus of claim 1, wherein the locations of the cursor have predetermined continuous values.

5. The apparatus of claim 1, wherein the probability has a large value when the distance between the cursor and each item is short.

6. The apparatus of claim 1, wherein the attribute of the list includes at least one of a color, an area, a shape, a sound, and a vibration.

7. A method of providing feedback of a location of a cursor in a tilt-based list search, the method comprising:

calculating and changing the location of the cursor according to a tilt angle;

calculating probabilities of the cursor being located at items of each list according to the calculated location of the cursor; and

changing an attribute of the list according to the calculated probability and displaying the list.

8. The method of claim 7, further comprising:

calculating the tilt angle.

9. The method of claim 7, wherein, in the calculating and changing of the location of the cursor according to the tilt angle, the location of the cursor is changed according to a tilt angle and a tilt direction of a portable apparatus.

10. The method of claim 7, wherein the locations of the cursor have predetermined continuous values.

11. The method of claim 7, wherein the probability has a large value when the distance between the cursor and each item is short.

12. The method of claim 7, wherein the attribute of the list includes at least one of a color, an area, a shape, a sound, and a vibration.
