Virtual Icon Capture for Immersive VR Perspective Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted display (HMD) devices struggle to capture and share the immersive experiences of virtual reality, as traditional image capture methods fail to convey the user's perspective and emotions within a virtual space effectively.
Innovation Solution
An electronic device with a display unit and controller that generates a virtual icon for capturing virtual spaces, allowing users to recognize their position and generate capture images based on touch inputs, enabling the creation of 360-degree images that reflect their experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional image capture methods are used in virtual reality, then the device structure remains simple, but the ability to convey user perspective and emotions is insufficient
Solution Approach 1:
The patent creates a virtual icon that copies and represents the user's position and perspective in the virtual space. By displaying a virtual icon on the HMD display that corresponds to the user's location, the system captures perspective information without requiring physical cameras, thus resolving the contradiction between information completeness and device complexity
Solution Approach 2:
The virtual icon acts as an intermediary between the user's physical position and the captured image data. This intermediary element translates the user's perspective into captureable information, enabling the system to convey user emotions and perspective without adding complex external camera hardware
2Measurement precision
If additional external cameras are added to capture virtual space, then the capture quality improves, but the device complexity and weight increase
Solution Approach 1:
The HMD display unit serves itself by using its own display functionality to create the virtual icon that represents user position. The system uses the existing display hardware to perform the capture function, eliminating the need for separate external cameras and reducing overall device complexity while maintaining capture precision
Solution Approach 2:
The display unit performs multiple functions: it displays virtual reality content and simultaneously creates the virtual icon for position capture. This multi-functionality eliminates the need for dedicated capture hardware, reducing device complexity while maintaining measurement precision for virtual space capture
3Loss of information
If 2D or 3D images are captured to represent virtual space, then the image format is simplified, but the expression of various views and emotions is limited
Solution Approach 1:
The system segments the capture function into two parts: the HMD display unit creates the virtual icon representing user position, and the controller processes this information to generate the final capture image. This segmentation allows complex emotion and perspective expression while keeping the user interface simple, as the user only needs to interact with the virtual icon rather than complex capture controls

AI summary
An electronic device including a display; and a controller configured to display a playback screen of virtual reality content on the display, in response to a capture command while displaying the playback screen of the virtual reality content, display a virtual icon on the playback screen, and in response to a touch input applied to the virtual icon, capture an image of a virtual space of the virtual reality content based on a position of a user in the virtual space and corresponding to a touch level of the touch input.
