Scrollable Text Navigation for Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for navigating media playback on computing devices are uninteresting and lack interactivity, negatively impacting the user experience by not effectively utilizing text associated with media content.
Innovation Solution
A system and method that synchronizes audio with text, allowing users to scroll through and select text segments to navigate media playback, enabling interactive media navigation by displaying relevant text segments based on playback time and allowing users to jump to specific parts of the media content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional scrubbing elements (slider, button, marker) are used for navigation, then navigation function is achieved, but user experience is uninteresting and lacks interactivity
Solution Approach 1:
The patent combines the navigation function with the existing text display element. Instead of using separate scrubbing elements, the text itself becomes the navigation interface. When users scroll or select text, they simultaneously navigate through media content and interact with text, merging two functions into one element.
Solution Approach 2:
The text element serves multiple functions: it displays media-related text information and simultaneously acts as a navigation control. By making the text selectable and linking it to playback position, the same element performs both information display and navigation control, reducing the need for separate interface elements.
2Loss of information
If text is displayed during media playback, then information is provided, but navigation interactivity is lost
Solution Approach 1:
The text element transitions from a static display component to a dynamic interactive element. The text can be scrolled, selected, and clicked, with its state changing based on user interaction. When text is selected, it triggers navigation to the corresponding media position, making the text display dynamic and responsive to user actions.
Solution Approach 2:
The system provides feedback by linking text selection to playback navigation. When users select text, the system responds by jumping to the corresponding media position and playing that segment. This feedback loop transforms passive text display into active navigation control, maintaining both information delivery and interactivity.

AI summary
A computing device can periodically acquire a current track time for a media content item being played. The device can periodically compare the current track time with a respective start time and a respective end time for each line (or segment) in a plurality of lines of text (or segments of text) associated with the media content item. If the device determines that the current track time is between start and end times for a given line of text, then the device can display the given line of text. A user of the device can scroll through the lines of text associated with the media content item. If the user selects a particular line of text, the device can identify a start time for the selected line of text. The device can then play the media content item at the identified start time of the selected line of text.
