AR Display Transparency Control via Gaze Offset Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality display systems face challenges in providing a user-friendly experience as they often disturb or obstruct the user's vision by displaying virtual elements without considering the user's point of focus, leading to visual clutter and distractions.
Innovation Solution
A system that determines the user's point of focus and generates control signals to dynamically modify the transparency of visual elements in the transparent display area based on the offset distance from the display, ensuring that virtual elements are transparent when not in focus and opaque when focused on, thereby enhancing the user's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual elements are displayed in the transparent display area, then information is provided to the user, but the user's vision is obstructed and visual clutter increases
Solution Approach 1:
The transparency of visual elements is dynamically adjusted based on the user's point of focus. When the user focuses on a physical object, the visual elements become more transparent to reduce obstruction. When the user focuses on the display area, the visual elements become more opaque to improve visibility. This dynamic adaptation resolves the contradiction between providing information and avoiding visual obstruction.
Solution Approach 2:
The system changes the transparency parameter of visual elements according to the offset distance between the user's point of focus and the transparent display area. By modifying this physical parameter based on real-time focus detection, the system optimizes both information delivery and visual comfort, eliminating the fixed trade-off between these conflicting requirements.
2Loss of information
If visual elements are always visible, then information is continuously provided, but user comfort decreases due to distractions when not in focus
Solution Approach 1:
The system uses feedback from focus detection to continuously adjust visual element transparency. The focus detection unit provides real-time information about the user's point of focus, and the processing unit uses this feedback to modify display characteristics. This closed-loop feedback mechanism ensures information continuity while maintaining user comfort by adapting to the user's attention state.
Solution Approach 2:
Rather than maintaining a static visibility state, the system dynamically adjusts visual element transparency based on user focus. This dynamic behavior allows the system to provide continuous information when needed while reducing distractions when the user is focusing on physical objects, thereby improving user comfort without sacrificing information continuity.
3Object-affected harmful factors
If transparency is increased to reduce obstruction, then visual comfort improves, but visibility of virtual elements decreases
Solution Approach 1:
The system applies different transparency levels to different visual elements based on their relevance to the user's focus. Visual elements near the user's point of focus maintain higher opacity for visibility, while elements farther from the focus point become more transparent to reduce obstruction. This local differentiation resolves the contradiction by applying transparency selectively rather than uniformly.
Solution Approach 2:
The transparency of each visual element is dynamically adjusted based on its position relative to the user's point of focus and the offset distance. This dynamic local adjustment allows the system to maintain visibility of relevant elements while reducing obstruction from peripheral elements, resolving the contradiction between these two requirements.

AI summary
Proposed is a display control system for an augmented reality, AR, display system, the AR display system comprising a transparent display area adapted to augment an object or scene viewable through the transparent display area by displaying a visual element in the transparent display area. The display control system comprises: a focal point detection unit adapted to determine a point of focus of a user; and a processing unit adapted to determine an offset distance by which the determined point of focus of the user is spaced from the transparent display area, and to generate a control signal for modifying the transparency of the visual element based on the determined offset distance.
