Abstract

A method of displaying points of interest in a personal navigation device includes displaying a map on a display of the personal navigation device, receiving touch input at a touched position of the display, displaying points of interest located near the touched position, wherein the points of interest are represented by icons, each icon being connected to its location on the map with a line extending out from the touched position, and spreading out the icons around the touched position to separate the icons from each other, the spread out icons being displayed in a pattern around the touched position, wherein a length of the line connecting each icon to its location on the map is not directly proportional to a distance from the corresponding point of interest to the touched position.

Claims

1. A method of displaying points of interest in a personal navigation device, the method comprising:

displaying a map on a display of the personal navigation device;

receiving touch input at a touched position of the display;

displaying points of interest located near the touched position which were previously hidden before receiving touch input at the touched position, wherein the points of interest are represented by icons, each icon being connected to its location on the map with a line extending out from the touched position; and

spreading out the icons around the touched position to separate the icons from each other, the spread out icons being displayed in a pattern around the touched position, wherein for each icon, a length of the line connecting the icon to its location on the map is not directly proportional to a distance from the corresponding point of interest to the touched position.

2. The method of claim 1, wherein as the number of displayed icons increases, the icons spread out away from the touched position.

3. The method of claim 1 further comprising stopping displaying additional icons when the number of displayed icons is greater than an upper threshold.

4. The method of claim 1 further comprising displaying icons for a predetermined time period after the touch input is no longer received.

5. The method of claim 4 further comprising controlling icons to fade away gradually after the predetermined time period has elapsed.

6. The method of claim 4 further comprising controlling icons to pop and disappear after the predetermined time period has elapsed.

7. The method of claim 1, wherein positions of icons shift to avoid overlapping with other icons.

8. The method of claim 1, wherein positions of icons shift to prevent the lines that connect icons to their respective locations on the map from intersecting with each other.

9. The method of claim 1 further comprising:

receiving touch input directed to a displayed icon; and

displaying additional information about the point of interest corresponding to the displayed icon for which touch input has been received.

10. The method of claim 1, wherein the pattern that the icons are displayed in is a circle in which a location of the touched position on the map is at a location other than the center of the circle, the icons being positioned on a circumference of the circle.

11. The method of claim 1, wherein the pattern that the icons are displayed in is a circle or a plurality of concentric circles, each of the icons being positioned on a circumference of one circle.

12. The method of claim 1, wherein the pattern that the icons are displayed in is a spiral line, each of the icons being positioned on the spiral line.

13. The method of claim 1, wherein the pattern that the icons are displayed in is a polygon, each of the icons being positioned on a perimeter of the polygon.

14. The method of claim 1, wherein the pattern that the icons are displayed in is a polygon in which a location of the touched position on the map is not located within the polygon, the icons being positioned on a perimeter of the polygon.

15. The method of claim 1, wherein the pattern that the icons are displayed in is a plurality of concentric polygons, each of the icons being positioned on a perimeter of one of the plurality of concentric polygons.

16. The method of claim 1, wherein the pattern that the icons are displayed in is a straight line, each of the icons being positioned on the straight line.

17. The method of claim 1, wherein the pattern that the icons are displayed in is a plurality of straight lines, each of the icons being positioned on one of the plurality of straight lines.

18. The method of claim 1, wherein the pattern that the icons are displayed in is an ellipse in which a location of the touched position on the map is not located within the ellipse, the icons being positioned on a circumference of the ellipse.

19. The method of claim 1, wherein displaying points of interest located near the touched position comprises displaying points of interest located near the touched position when receiving touch input.

20. The method of claim 1, wherein displaying points of interest located near the touched position comprises displaying points of interest located near the touched position in response to receiving touch input at the touched position.
