Playback State Control via Text List Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content playback systems lack finer controls for users, such as precise playback position seeking, repeat playback, and speed control, which limits user convenience and intuitive interaction.
Innovation Solution
An information processing apparatus and method that includes a position change detecting unit, a playback state control unit, and a display control unit to detect continuous position changes on a screen and control playback states, displaying a text list sorted by elapsed times to enable intuitive control of playback positions, speeds, and repeat functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional playback control interfaces are used, then basic playback functions are available, but user convenience and interaction intuitiveness are insufficient
Solution Approach 1:
The text list automatically updates and reflects the current playback position without requiring manual intervention from the user. As the user interacts with the content (seeking, playing, pausing), the text list self-adjusts to show relevant text segments, providing a hands-off enhancement to the user experience.
Solution Approach 2:
The text list serves as an intermediary element between the playback controls and the content. Instead of directly manipulating playback parameters, users interact with the text list (selecting text segments), which then translates these interactions into appropriate playback state changes, making the control process more intuitive and easier to understand.
2Measurement precision
If manual playback position seeking is used, then playback control is possible, but precision and user experience are limited
Solution Approach 1:
The text list divides the content into discrete text segments, each corresponding to a specific playback position. This segmentation allows users to precisely navigate to any desired position by selecting the appropriate text segment, rather than manually adjusting a continuous playback slider, thereby achieving both precision and ease of operation.
Solution Approach 2:
The text list is prepared in advance with all text segments and their corresponding playback positions mapped out. This preliminary organization enables users to directly jump to any desired playback position by simply selecting the relevant text segment, eliminating the need for gradual seeking and improving both precision and user experience.
3Adaptability or versatility
If basic playback controls are provided, then simple playback is supported, but finer controls for repeat playback and speed adjustment are lacking
Solution Approach 1:
The text list serves multiple functions: it acts as a table of contents for navigation, a timestamp reference for positioning, and an interactive control mechanism for playback state adjustment. By selecting different text segments or using different interaction patterns with the text list, users can access seeking, repeat playback, and speed control functions, making a single interface element perform multiple control roles.
Solution Approach 2:
The patent combines navigation, timing, and playback control functions into a single integrated text list interface. Instead of having separate controls for seeking, timestamp display, and playback state management, all these functions are merged into the text list interaction, reducing the overall control system complexity while enhancing versatility.
Data Source
AI summary
There is provided an information processing apparatus including a position change detecting unit that detects a position change of an operating body on a screen, a playback state control unit that controls a playback state of a content, and a display control unit that at least displays a part or all of a text list in which text data items associated with elapsed times in a playback of the content are sorted in an order of the elapsed times, on the screen. The playback state control unit controls the playback state of the content in response to a continuous position change of the operating body detected by the position change detecting unit on the text list displayed by the display control unit.
