Adaptive Download Rate Control via User Gaze Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in managing bandwidth demands efficiently, particularly during limited connectivity or bandwidth, where content downloads can be slow and require excessive bandwidth, affecting user experience.
Innovation Solution
A method and system that utilize sensors to analyze a user's gaze and interest in content, adjusting the download rate accordingly, prioritizing content based on user attention to optimize bandwidth usage and reduce data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content is downloaded at a constant high rate, then download speed is improved, but bandwidth consumption increases and user experience deteriorates during limited connectivity
Solution Approach 1:
The patent implements dynamic download rate adjustment based on real-time user gaze detection. The system transitions from static constant-rate downloading to dynamic adaptive downloading, where the download rate changes continuously according to user attention levels. This resolves the contradiction by making download speed responsive to actual user needs rather than maintaining a fixed high rate that wastes bandwidth.
Solution Approach 2:
The system incorporates feedback loops where user gaze data is continuously monitored and fed back to adjust download parameters. The gaze detection system provides real-time feedback about user attention, which is then used to modulate the download rate. This closed-loop control mechanism ensures bandwidth is allocated efficiently based on actual user interest rather than blind high-speed downloading.
2Reliability
If all content is downloaded simultaneously, then complete content availability is improved, but bandwidth demand increases and download time extends
Solution Approach 1:
The system performs preliminary actions by pre-downloading only the content that user gaze indicates is currently being viewed or is most important. Rather than waiting until all content is needed, the system anticipates user needs based on gaze patterns and prioritizes downloading relevant content first, ensuring critical content is available when needed without downloading everything simultaneously.
Solution Approach 2:
The patent segments the download process into priority-based batches according to user gaze attention. Content is divided into segments based on importance determined by gaze duration and position, with high-priority segments downloaded first. This segmentation strategy ensures essential content becomes available quickly while less important content downloads in the background, reducing overall perceived download time.
3Reliability
If multiple images are downloaded for web page rendering, then complete page display is improved, but bandwidth consumption increases and rendering time extends
Solution Approach 1:
The system applies local quality differentiation by adjusting image download quality and resolution based on user gaze position. Images in the user's current field of view receive higher priority and better quality, while images outside the gaze area are downloaded at lower resolution or deferred. This local quality approach ensures the visible portion of the webpage renders completely and quickly while minimizing bandwidth consumption for non-visible content.

AI summary
A method of managing downloading of content includes receiving, by one or more processors of a computer system, a request to download content by a user, analyzing, by the one or more processors of the computer system, the gaze of the user relative to an intended location of the content on a display, determining, by the one or more processors of the computer system, an interest in the content based on the analyzing of the gaze of the user, and adjusting, by the one or more processors of the computer system, a rate of download of the content by the user based on the determining.
