Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to provide an enhanced user experience in virtual environments by effectively adjusting content size and depth based on user gaze and focal length, leading to suboptimal 3D perception.
Innovation Solution
A wearable device equipped with cameras and processors that adjust content size and depth in a virtual environment based on user gaze duration and focal length adjustments, utilizing multiple displays positioned for each eye to create a 3D perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If content size and depth are adjusted dynamically based on user gaze and focal length, then 3D virtual environment perception is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic adjustment of content size and depth based on real-time user gaze detection and focal length estimation. The system continuously monitors user interaction through camera-based gaze tracking and adapts the virtual content presentation accordingly, transitioning from static to dynamic control to enhance 3D perception accuracy
Solution Approach 2:
The system employs feedback mechanisms by detecting user gaze duration and focal length, then using this information to adjust content parameters. The camera-based gaze detection provides continuous feedback about user attention, which is processed to modify content size and depth, creating a closed-loop control system that improves measurement precision
2Adaptability or versatility
If gaze detection and content adjustment functions are added, then user experience is enhanced, but processing requirements and energy consumption increase
Solution Approach 1:
The system applies partial action by selectively adjusting content parameters only when gaze duration exceeds a reference threshold. Instead of continuously modifying all content attributes, the system performs targeted adjustments only when user attention indicates a need for adaptation, reducing unnecessary processing and energy consumption while still enhancing user experience

AI summary
This wearable device may comprise: a first display and a second display; a camera; a processor; and a memory for storing instructions. The instructions, when executed by the processor, may cause the wearable device to: display content having a first displaying size on the first display and the second display so that the content is perceived as being located at a first depth in a three-dimensional (3D) virtual environment; and when the content is displayed for a time period equal to or longer than a reference time, display the content in a second displaying size that is substantially the same as the first displaying size on the first display and the second display so that the content is perceived as being located at a second depth exceeding the first depth in the 3D virtual environment.
