Immersive Display System Perspective Adjustment

Solution Overview

Problem

Current immersive display systems that use 360-degree cameras restrict the viewer's perspective to the camera's center, leading to visual discontinuities and discomfort, as they only allow orientation changes without translational movement, causing the viewable world to move unnaturally with the viewer.

Innovation Solution

An immersive display system that allows adjustment of the virtual viewer position relative to the recorded position, enabling six degrees of freedom, including translational and rotational movements, to simulate real-world perspective changes, thereby enhancing the viewer's experience by allowing natural movement and reducing nausea.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the camera is locked to the viewer position, then the implementation is simple and represents a direct mapping, but the viewer experiences visual discontinuities and discomfort

Engineering Contradiction:

Improveimplementation simplicityVSAvoidviewer discomfort and nausea

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent separates the camera position from the viewer position, allowing independent control of recording location and viewing location. This segmentation enables the system to maintain simple camera operation while providing flexible viewer perspective adjustment, resolving the contradiction between implementation simplicity and viewer comfort.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the virtual camera position relative to the viewer based on detected viewer movements. Instead of a static locked relationship, the camera position becomes dynamic and adaptive, allowing the system to maintain simplicity while eliminating visual discontinuities that cause discomfort.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If the viewer can only change orientation, then the system remains simple, but the viewer cannot move translationally and experiences unnatural viewing

Engineering Contradiction:

Improvesystem complexityVSAvoidviewer movement freedom

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent adds translational degrees of freedom to the traditional rotational-only viewing system. By introducing positional adjustment in addition to orientational adjustment, the system enables natural movement simulation without proportionally increasing complexity, as the additional dimensional freedom is managed through software processing.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

Instead of requiring complex mechanical systems to physically move the camera or viewer, the patent uses computational methods to simulate positional changes. The virtual camera position is adjusted through image processing and rendering techniques, replacing mechanical complexity with software-based solutions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If the entire viewable world moves with the viewer translation, then the perspective remains consistent, but objects move in a non-intuitive way causing disconcerting effects

Engineering Contradiction:

Improveview consistencyVSAvoidnon-intuitive object movement

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent applies different transformation rules to different elements in the scene. The camera position adjusts with viewer movement to maintain consistent perspective, while individual objects within the scene maintain their fixed positions and orientations. This local differentiation allows view consistency while preventing non-intuitive object movement.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of moving the entire world with the viewer, the system inverts the approach by keeping the world stationary and adjusting only the camera position. This inversion maintains perspective consistency while preventing the disconcerting effect of objects moving non-intuitively across the field of view.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

An immersive display system with an adjustable perspective is provided herein. The immersive display system includes a viewing device suitable for displaying display information in an immersive environment, which is displayed relative to a virtual viewer position. The immersive display system includes an input device. The system also includes an image storage element that stores at least one photographic image. The immersive display system includes a processor configured to process the instructions for mapping the photographic image onto a 3-dimensional shape for display in an immersive environment on the viewing device. The system adjusts a virtual displayed position with respect to the virtual viewer position allowing for the viewer to experience the environment at a perspective different than the recorded perspective.
