HMD Virtual Object Visibility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays (HMDs) often hinder visual recognition of real objects due to the display of virtual objects, which is not adequately addressed in current augmented reality technologies, and there is a need for a solution that allows users to easily recognize real-world objects without obstruction.
Innovation Solution
A head-mounted display system that includes an image display unit and an augmented reality processing unit, which switches between two display aspects of virtual objects: a first aspect with higher visibility hindrance and a second aspect with lower visibility hindrance, allowing users to transition between them based on retention time, user requests, and focusing operations, thereby reducing the obstruction of real objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If virtual objects are displayed in a head mounted display, then augmented reality information is provided to the user, but visual recognition of real objects is hindered
Solution Approach 1:
The patent implements dynamic switching between two display aspects (first and second aspects) based on user interactions such as focusing operations. The display characteristics of virtual objects are not static but change over time, allowing the system to adapt between providing augmented reality information and reducing visibility hindrance to real objects.
Solution Approach 2:
The patent employs periodic switching between display aspects with a predetermined retention time period. After a user performs a focusing operation, the first display aspect is maintained for a specific duration (retention time) before transitioning to the second display aspect, creating a rhythmic pattern of information presentation that balances AR information delivery with visual recognition needs.
2Loss of information
If virtual objects are displayed with high visibility, then augmented reality information is effectively conveyed, but the real object recognition is obstructed
Solution Approach 1:
The system dynamically adjusts display characteristics based on user focus state. When a focusing operation is detected, the virtual object display is activated in the first aspect; when focus is released, it transitions to the second aspect with reduced visibility hindrance, making the system responsive to user needs in real-time.
Solution Approach 2:
The patent changes display parameters (such as transparency, size, or position of virtual objects) between the two display aspects. The first aspect uses parameters optimized for information delivery, while the second aspect uses parameters optimized for minimizing obstruction, allowing flexible adjustment of the balance between information delivery and recognition ease.
3Reliability
If virtual objects are continuously displayed, then augmented reality functionality is maintained, but user convenience deteriorates due to persistent visual obstruction
Solution Approach 1:
The system maintains augmented reality functionality through periodic display cycles rather than continuous display. The retention time period ensures AR information is presented for sufficient duration, while the transition to the second display aspect provides relief from visual obstruction, improving overall user convenience.
Solution Approach 2:
The system automatically switches between display aspects based on detected focusing operations without requiring explicit user commands. The augmented reality processing unit monitors user interaction and autonomously adjusts display characteristics, making the system self-adapting to user needs and improving convenience.

AI summary
A head mounted display, includes an image display unit enabling the user to visually recognize the virtual image, and an augmented reality processing unit causing the image display unit to form the virtual image including a virtual object displayed additionally to a real object actually existing in the real world, in which the augmented reality processing unit causes the virtual image including the virtual object in a first display aspect to be formed, and then causes the virtual image including the virtual object in a second display aspect to be formed after a predetermined retention time period has elapsed, and in which a degree of the visibility hindrance of the virtual object in the second display aspect for the real object is lower than a degree of the visibility hindrance of the virtual object in the first display aspect for the real object.
