Synchronized Audio Slide Seek Bar for Presentation Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing presentation services, it is difficult for users to intuitively determine the current slide page position on a time axis due to the limited display of thumbnails, requiring cumbersome navigation to find a specific page.
Innovation Solution
An application program that displays two synchronized seek bars on a terminal device and server, representing audio and slide playback positions on a time axis, allowing users to intuitively understand the slide page position by designating playback positions on either bar, with features like popup information and proportional time span display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If only a limited number of thumbnails are displayed on the distribution screen, then the interface remains simple and clean, but it becomes difficult to find a desired page when there are many pages (e.g., 100 pages)
Solution Approach 1:
The patent introduces a time axis dimension to organize and display thumbnails. Instead of displaying all thumbnails in a limited two-dimensional space, the thumbnails are arranged along a time axis that represents the chronological order of slides. This allows users to visually perceive the temporal progression of the presentation and easily locate specific pages by their position on the time axis, effectively solving the problem of navigating through many pages without requiring a large display area.
Solution Approach 2:
The patent segments the large number of thumbnails into manageable groups or sections along the time axis. By dividing the complete set of thumbnails into smaller segments that can be displayed within the limited screen area, users can navigate through these segments to find their desired page. This segmentation approach maintains interface simplicity while enabling efficient navigation through extensive content.
2Ease of operation
If a seek bar representing audio playback position is displayed, then audio navigation is enabled, but it is difficult to determine which slide page is currently being displayed
Solution Approach 1:
The patent merges the audio seek bar with the time axis representation of slide thumbnails. The same time axis that displays thumbnail positions also indicates the corresponding slide page information. When users interact with the seek bar at any position, they can simultaneously see both the audio playback position and the current slide page number or thumbnail, eliminating the information loss problem while maintaining ease of audio navigation.

AI summary
The present invention provides: an application program which assists with an intuitive understanding of the position of each page of a slide on a time axis; a terminal device controlling method; a terminal device; and a server. The application program of the terminal device, which plays a slide and an audio synchronized with the slide, makes a computer of the terminal device 3 function as a display control unit 32 which displays an interface 100 provided with a first interface 123 that represents a playback position of the audio and a second interface 135 that represents a playback position of each page of the slide, and function as a play control unit 32 which plays the slide and audio at designated playback position, wherein when a playback position of one among the first interface 123 and the second interface 135 is designated, the display control unit 32 makes a playback position of the other correspond to the designated playback position.
