Pseudo-Hologram Projection for Multi-Perspective VR Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HMD technologies limit the ability of a third person to understand a game or scenario by only allowing them to view from the player's perspective, making it difficult to grasp the overall situation.
Innovation Solution
A method and apparatus that create a three-dimensional pseudo-hologram of a first user and their surroundings, allowing a second user to view the first user's video feed using a head-mounted display by projecting a hologram video onto a screen between them, enabling a broader perspective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a third person watches a game using HMD technologies, then they can view the content, but they can only see it from the player's viewpoint and cannot understand the game overall
Solution Approach 1:
The patent transitions from a single first-person viewpoint to multiple dimensional viewpoints by capturing and displaying video feeds from multiple cameras positioned at different locations. This allows the third person to view the game environment from various angles simultaneously, adding spatial dimensions to the viewing experience and enabling comprehensive understanding of the game situation.
Solution Approach 2:
The patent divides the single viewpoint into multiple segmented viewpoints by using multiple cameras positioned at different locations. Each camera captures a specific portion of the game environment, and these segmented views are combined to provide a comprehensive multi-perspective display, allowing the third person to understand both the player's perspective and the overall game situation.
2Area of stationary object
If a single viewpoint camera is used in VR content, then the player's perspective is maintained, but the ability to show surroundings and objects to a third person is limited
Solution Approach 1:
The patent makes the camera system multi-functional by using the same multiple cameras for both first-person viewpoint capture and third-person surrounding capture. The camera system serves dual purposes: maintaining the player's first-person perspective while simultaneously providing comprehensive views of the game environment for third-person observation, thereby increasing visible area without proportionally increasing complexity.

AI summary
A method for presenting a mapping pseudo-hologram using individual video signal output of a real-time engine according to an embodiment of the present disclosure includes: (a) creating a partial viewpoint video including a character of a virtual reality content corresponding to a first user through a camera positioned at any one point in the virtual reality content; (b) creating a hologram video including at least one of objects around the character in the partial viewpoint video; and (c) projecting the hologram video onto a hologram screen placed between the first user and a second user different from the first user, and in the process (c), the hologram video is projected to be overlaid on the first user when the second user sees the first user.
