AR Display Control for Walking-State Visibility and View Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) technologies often obstruct the user's field of view with virtual objects, leading to discomfort and reduced visibility of both the virtual objects and the real-world scenery, especially when the user is walking.
Innovation Solution
An information processing device equipped with sensors to detect walking states, which enlarges or repositions virtual objects within the field of view display range to maintain visibility while the user is moving, using a central and peripheral zone system to optimize display control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display item is enlarged to improve visibility while the user is walking, then the visibility of the virtual object is improved, but the field of view obstruction increases
Solution Approach 1:
The display item's size and position are dynamically adjusted based on the user's walking state. When the user is detected to be walking, the display item is enlarged and repositioned to the peripheral zone, creating a dynamic display adaptation that balances visibility with field of view preservation.
Solution Approach 2:
Different zones (central zone and peripheral zone) are treated differently based on the user's activity state. The system applies local quality by selectively enlarging and repositioning display items in the peripheral zone when walking is detected, while maintaining normal display in the central zone during stationary states.
2Object-affected harmful factors
If the display item is repositioned to the peripheral zone to reduce field of view obstruction, then the field of view visibility is improved, but the display item visibility may be reduced
Solution Approach 1:
The system dynamically adjusts display item position based on user state. When walking is detected, the display item is repositioned to the peripheral zone where it remains visible without obstructing the central field of view, balancing both visibility requirements.
Solution Approach 2:
The display item is moved from the central dimension to the peripheral dimension of the field of view. This spatial redistribution allows the display item to remain visible while no longer obstructing the central viewing area, solving the contradiction between visibility and obstruction.
3Ease of operation
If the display item is enlarged to maintain visibility during walking, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The system uses the walking detection sensor to automatically trigger display adjustments without requiring user input. The processor autonomously determines when to enlarge and reposition display items based on sensor data, making the system self-regulating and reducing operational complexity.
Solution Approach 2:
The system implements a feedback loop where the walking detection sensor continuously monitors user state, and the processor adjusts display parameters accordingly. This closed-loop control simplifies operation by automatically adapting to user needs based on real-time feedback from the sensor.
