Wearable Display Image Masking for Artifact-Free Simulation View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying environments in simulations, such as those using head-mounted displays, restrict the user's field of view and can result in artifacts due to partial transparency, while also limiting interaction options and restricting virtual object placement to predetermined positions.
Innovation Solution
A method utilizing a set of 3D glasses as a display unit, which creates a display image by superimposing interaction environment recordings with environment images using an image mask, allowing for an unrestricted field of view and realistic interaction by associating individual positions on the recordings with the display image, and adjusting image parameters such as sharpness and brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If partially transparent display media are used to overlay virtual representation with environment, then virtual objects can be displayed, but visible artifacts occur and field of view is restricted
Solution Approach 1:
The patent uses image recording units to capture real environment images and creates virtual copies of interaction elements (hands, objects) that are superimposed onto the recorded images. This copying approach allows virtual elements to be integrated into the real environment view without using transparent displays, thereby avoiding visible artifacts while maintaining full field of view.
2Adaptability or versatility
If head-mounted displays with virtual screens are used, then simulation environment can be displayed, but field of view is restricted and artifacts occur
Solution Approach 1:
The patent replaces the mechanical transparent display system with an image processing system. Instead of using physical transparent screens that block part of the view, the system captures real environment images with recording units and superimposes virtual elements through image processing, thereby eliminating the field of view restriction while maintaining simulation display capability.
3Ease of manufacture
If predetermined positions are used for virtual objects, then display simplicity is maintained, but interaction realism is limited
Solution Approach 1:
The patent implements dynamic positioning of virtual interaction elements based on the detected position of the user and their hands. Instead of fixed predetermined positions, the virtual elements move and adjust their location in response to user actions, thereby enhancing interaction realism while maintaining relatively simple display implementation through image processing.

AI summary
A method represents an environment via a display unit arranged on a person and visible for the person as a display image within the scope of a simulation. The simulation is carried out in an interaction environment, wherein a number of actuatable interaction elements are arranged in the interaction environment. An interaction environment image capture, depicting the interaction environment, is created by use of a first image capturing unit arranged on the person or relative to the person. A position of the person is determined in the interaction environment and based on the position of the person an environment image is provided. An image mask is provided which depicts the individual interaction elements contained in the interaction environment image capture and is represented in the display image. The interaction environment image capture and the environment image are superimposed using the image mask and then displayed on the display unit.
