Immersive View Control Using Presenter-Defined Aperture Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersive environments lack the ability for a presenter to control the field of view of multiple users, particularly in scenarios where a lecturer needs to manage the display or visibility of students, as existing systems only allow users to control their own view based on personal inputs.
Innovation Solution
A method and processing unit that allows a presenter to input an aperture with a predefined shape, dynamically analyze the real-time scene to identify viewable objects, and generate a view-controlled scene by creating spatial image layers to control the field of view of attendees, including options for virtual or physical apertures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users control their own view based on personal inputs, then user autonomy and personalization are improved, but the ability of a presenter to control multiple users' field of view deteriorates
Solution Approach 1:
The patent introduces a presenter as an intermediary who receives inputs from one or more users and generates controlled view scenes for other attendees. The presenter acts as a mediator between user inputs and the rendering system, enabling centralized control while maintaining the ability for individual users to provide input signals. This resolves the contradiction by adding a control layer that enables both user autonomy and presenter control.
Solution Approach 2:
The patent segments the control system into multiple independent components: individual user input devices, a presenter control interface, and a rendering system that processes different input types. This segmentation allows different users to operate independently while the presenter can override or guide their views, resolving the contradiction between user autonomy and presenter control capability.
2Loss of information
If a virtual viewfinder is displayed to guide user focus, then user attention to region of interest is improved, but system complexity increases
Solution Approach 1:
The patent uses a virtual viewfinder that is essentially a graphical copy or representation of the desired field of view boundary, displayed as an overlay on the immersive scene. This simple graphical copy guides user attention without requiring complex system changes, resolving the contradiction between improving focus control and maintaining system simplicity.
Solution Approach 2:
The virtual viewfinder utilizes visual properties such as color, transparency, and boundary rendering to guide user attention. By manipulating these visual attributes of the viewfinder overlay, the system effectively controls user focus on regions of interest without adding substantial system complexity.

AI summary
Method, processing unit, and non-transitory computer-readable medium for controlling view of user in immersive environment. Input, in form of an aperture, is received from presenter to control the view. A real-time scene is analyzed to identify viewable objects and spatial image layers are created based on the aperture. Further, by sequentially combining the plurality of spatial image layers, a view-controlled scene is generated for the at least one attendee. The view of the at least one attendee is controlled by replacing the real-time scene with the view-controlled scene in the immersive environment.
