Virtual Display Position Matching for Natural User Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When wearable devices such as HMDs provide virtual spaces, the mismatch between the user's position in the real and virtual spaces can lead to unnatural behaviors.
Innovation Solution
A display device and method that includes real and virtual object information acquisition units to match the positions and postures of real and virtual objects, calculating a positional relationship in the virtual space based on the real space, and acquiring user positional information to align the user's position in the virtual space with their real-space position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user's position in virtual space is freely determined without matching real-space position, then the user has freedom of movement in virtual space, but the user's behavior becomes unnatural
Solution Approach 1:
The system changes the parameter of user position in virtual space by calculating it based on real-space position information. The user position acquisition unit acquires real-space position, matches it with virtual object position, and calculates the corresponding virtual-space position, thereby adjusting the position parameter to ensure natural behavior while maintaining freedom of movement.
2Reliability
If the system calculates user position based on matching real and virtual object positions, then user behavior becomes natural, but the system complexity increases
Solution Approach 1:
The system segments the position calculation process into distinct functional units: a real object information acquisition unit that获取s real-space position, a virtual object information acquisition unit that获取s virtual object position, and a user position acquisition unit that performs the matching and calculation. This segmentation makes the complex system more manageable and modular.
Solution Approach 2:
The user position acquisition unit acts as an intermediary that receives position information from both real and virtual object acquisition units, performs the matching calculation, and outputs the calculated user position. This intermediary structure simplifies the overall system architecture by centralizing the complex matching logic in a dedicated component.

AI summary
Behaviors of a user are made natural in a virtual space. A display device includes a real object information acquisition unit configured to acquire information on a position of a real object that is an object in a real space in which a user exists and information on a positional relationship in the real space between the real object and the user, the position being in the real space; a virtual object information acquisition unit configured to acquire information on a position of a virtual object that is an object in a virtual space, the position being in the virtual space; and a user position acquisition unit configured to match positions and postures of the real object and the virtual object, calculate a positional relationship in the virtual space between the virtual object and the user in the virtual space based on the information on the positional relationship in the real space, and acquire user positional information presenting a position of the user in the virtual space based on the positional relationship in the virtual space.
