Abstract

A touch screen control method for controlling a playback of multimedia content using a timeline-based interface includes detecting a selection at a specific location on the timeline; and selectively zoom-displaying an area around the location where the selection is detected the position on the timeline where the event trigger has occurred.

Claims

1. A method for controlling a playback of content displayed on a touch screen using a timeline, comprising:

detecting a selection at a particular location on the timeline for a predetermined time period; and

selectively zoom-displaying an area around the detected location on the timeline where the selection is detected.

2. The method of claim 1, wherein the zoom-displaying comprises selectively zoom-displaying the detected location on the timeline where the selection is detected using one of:

a one-dimensional fisheye effect, a two-dimensional fisheye effect, and a circular fisheye lens effect.

3. The method of claim 1, wherein the selection is made:

(a) when a contact on the detected location lasts for the predetermined time period or more;

(b) when a predetermined gesture pattern is detected;

(c) when a contact pressure greater than a predetermined pressure level is detected;

(d) when substantially the same selected location is touched two or more times within a predefined time period;

or (e) when an event trigger request button is selected.

4. The method of claim 3, wherein the zoom-displaying comprises increasing a display zoom ratio proportionally to a duration of the selection detected on the particular location or a number of selections detected on the particular location.

5. The method of claim 1, wherein the zoom-displaying comprises subdividing a slide position adjustment unit of the timeline proportionally to a display zoom ratio.

6. The method of claim 1, wherein the zoom-displaying comprises adjusting at least one of a display zoom ratio and a display zoom ratio increment unit depending on a size of the content.

7. The method of claim 1, wherein the zoom-displaying comprises adjusting a slide position adjustment unit on the time line depending on a size of the content.

8. The method of claim 1, wherein the detected selection is made on a slider on the timeline to generate a zoom-displayed bar.

9. The method of claim 1, further comprising restoring a zoom-displayed bar to an initial form when the detection is released.

10. An apparatus comprising a display and a touch-sensitive surface allowing a playback of content using a timeline-based interface displayed thereon, comprising:

a controller for synchronizing a slider position on a timeline with the content being played back, and for selectively zoom-displaying an area around a particular location of the timeline whereto a selection is detected.

11. The apparatus of claim 10, wherein the controller selectively zoom-displays the detected location on the timeline where the selection is detected based on any one of:

a one-dimensional fisheye effect, a two-dimensional fisheye effect, and a circular fisheye lens effect.

12. The apparatus of claim 11, wherein the controller increases a display zoom ratio proportionally to a duration of the selection detected on a particular location on the time line or a number of selections detected on the particular location.

13. The apparatus of claim 10, wherein the controller subdivides a slide position adjustment unit proportionally to a display zoom ratio.

14. The apparatus of claim 10, wherein the controller adjusts at least one of a display zoom ratio and a display zoom ratio increment unit depending on a size of the content.

15. The apparatus of claim 10, wherein the display controller adjusts a slide position adjustment unit depending on a size of the content.

16. A system, comprising:

a processor; and

a computer readable storage medium coupled with the processor, the processor configured to perform the steps of;

display at least a portion of content and a slider over a timeline to control selection of the content being played back;

detect a contact on the timeline over a predetermined time period; and

zoom-display an area around the detected contact.

17. The system of claim 16, wherein the zoom-display of the area around the detected contact is achieved through one of:

a one-dimensional fisheye effect, a two-dimensional fisheye effect, and a circular fisheye lens effect.

18. The system of claim 16, wherein the contact comprises one of:

a predetermined gesture pattern, a contact pressure greater than a predetermined pressure level, multiples of the contact detected that are substantially the same within a predefined time period, and responsive to user interaction including an activation of a request button.

19. The system of claim 16, wherein the processor increases a display zoom ratio of the zoom display according to a duration of the contact or a number of contacts detected thereon.

20. The system of claim 16, wherein the processor cause a display to generates a zoom-displayed bar when the contact is made on the slider.
