Hologram Positioning via Camera Mediator in Extended Reality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality (ER) systems face challenges in providing intuitive and efficient interaction methods with holograms across different immersive platforms, particularly between 3D and 2D environments, leading to varying levels of complexity and user experience.
Innovation Solution
A computer system and method that allows holograms to be moved from one location to another within an ER scene by defining a triggering action, enabling progressive movement and concurrent scene panning, ensuring the hologram remains visible and interactable across different immersive platforms, including VR, AR, and MR systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If holograms are moved to locations outside the current perspective view in 2D ER platforms, then the hologram can be positioned at the desired destination, but the user loses visibility of the hologram during movement
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures and displays the hologram's movement in real-time. The camera view acts as a mediator between the hologram movement and user observation, allowing users to see the hologram being moved to locations outside the original perspective view without breaking immersion or requiring platform-specific interactions
2Ease of operation
If different interaction methods are used for 2D and 3D ER platforms, then each platform can optimize its user experience, but the system complexity increases and consistency across platforms deteriorates
Solution Approach 1:
The patent implements a universal camera-based interaction model that works across both 2D and 3D ER platforms. Instead of creating separate interaction paradigms for each platform type, the system uses camera views as a common interface that adapts to different platform capabilities, allowing the same fundamental interaction pattern (selecting camera view → moving hologram) to function consistently across VR headsets, AR glasses, and 2D display devices
Solution Approach 2:
Rather than having the hologram directly respond to platform-specific gestures or commands, the patent inverts the approach by using camera views as the primary interface. The user selects a camera view, and the system automatically handles the hologram movement logic, reversing the traditional model where the hologram would directly respond to user input based on platform capabilities
3Manufacturing precision
If manual dragging and dropping is used to move holograms in 2D ER platforms, then precise positioning is achieved, but the interaction complexity and time required increase significantly
Solution Approach 1:
The patent applies preliminary action by allowing users to select a destination camera view before the hologram actually moves. The system prepares the movement path and calculates the destination based on the selected camera's position and orientation, enabling the hologram to be transported directly to the correct location without requiring incremental manual adjustments or dragging operations

AI summary
Techniques for enabling an action to be performed with respect to a hologram that is displayed in a scene are disclosed. A location for a hologram is defined. Defining the location includes defining a triggering action that, when detected, causes the hologram to progressively move from whatever location the hologram is located at a time when the triggering action is detected to the defined location. In response to detection of the triggering action, the hologram progressively moves to the second location.
