Dynamic Closed Caption Modification for Video Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closed captioning systems obscure desired content when activated, limiting viewers' ability to see both captions and video simultaneously, and do not allow for easy modification of caption location, size, or opacity, leading to viewer frustration.
Innovation Solution
A system and method that enable viewers to modify the location, size, opacity, and duration of closed captions, allowing for simultaneous viewing of captions and video content, including the ability to rewind and reposition captions to avoid missed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If closed captioning is activated to provide additional information for hard of hearing viewers, then accessibility is improved, but the desired video content becomes obscured
Solution Approach 1:
The closed caption box is made dynamically repositionable and resizable by the viewer. The system allows real-time modification of caption location, size, and opacity based on viewer preference, transforming the static caption display into a dynamic element that can adapt to different viewing scenarios and prevent obscuration of important video content.
Solution Approach 2:
The system allows different parts of the screen to have different qualities by enabling viewers to position captions in specific locations where they least interfere with important video content. The caption box can be locally adjusted in size and opacity to maintain readability while minimizing obstruction of desired content in specific screen regions.
2Ease of operation
If closed caption location and size are fixed to ensure readability, then ease of operation is improved, but adaptability to different viewing preferences deteriorates
Solution Approach 1:
The caption display system transitions from fixed parameters to dynamic adjustable parameters. Viewers can modify location, size, and opacity in real-time, allowing the system to maintain ease of operation through default settings while providing adaptability when viewers need to customize their viewing experience.
Solution Approach 2:
The caption system is designed to serve multiple functions and viewer preferences through a unified interface. The same caption box can be positioned and sized differently to accommodate various viewing scenarios, making the system universally applicable to different viewer needs without requiring multiple separate systems.
3Ease of operation
If closed caption opacity is increased to improve readability, then ease of operation is improved, but the obscuration of desired content increases
Solution Approach 1:
The system allows viewers to adjust the opacity parameter of the closed caption box to find the optimal balance between readability and content visibility. By making this parameter changeable, viewers can increase opacity when readability is the priority and decrease it when viewing underlying content is more important, resolving the contradiction through user-controlled parameter adjustment.
