In this disclosure, a method of dragging the progress bar instead of the slider to get to the accurate position is proposed. This relative movement behavior is like the violin bow striking against the string: the string stays unmoved, while the violin bow moves back and forth. In this way, you can precisely adjust the progress within the time area nearby the slider during fast-forward/backward, which might be hard to control by using existing techniques, especially on small mobile devices.

Precisely adjusting the progress by dragging the progress bar

Problem and background

Users find it difficult to control the slider precisely and easily on small multi-touch screen devices. When they want to move to a specific time point, they have to adjust the slider by dragging and dropping it back and forth. Especially to the big fingertip guys, the tiny slider is a big headache since the fingertip is always likely to obscure the visual feedback of the slider, making it difficult to place the slider at a desired position; and the fingertip might also block the content that is being played on the screen.

Existing techniques and their drawbacks

1. Dragging the slider to a specific time point

A method is applied widely for both PC and mobile devices to reach a specific time point by dragging the slider on the bar slowly . Drawbacks: Too tiny slider hidden behind the finger on mobile devices does not help fine -tuning and blocks the main visual area for preview.

2. Swiping the screen to fast-forward/backward to a specific time point

A method is proposed to enable finger-moving forward or backward at any point on the screen to a specific time point. Drawbacks: The fast-forward/backward is at a fixed rate, e.g., a certain number of frames each time; No visual feedback on the progress bar; No preview is supported.

Usage scenarios

Phase 1 (rough adjustment): Use the normal slider-moving method to drag the slider roughly to a target area, as illustrated in


the 1stfigure.

Phase 2 (precise adjustment): Use the new bar-moving method to make further adjustments more precisely, as illustrated in the


2ndand the 3rdfigure.

During the precise adjustment, the slider stays unmoved to the screen.

On the screen, there's buff...
