Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional computing devices have limitations in rendering highly detailed 3D graphical elements due to their reliance on low-level 3D graphics libraries like OpenGL or Direct3D, which struggle with latency and cannot provide the performance needed for head-tracking based user interfaces that demand immersive and interactive 3D experiences.

Innovation Solution

An independent 3D rendering engine is integrated with the UI framework of the operating system to draw and render 3D content, allowing for features beyond the capabilities of built-in graphics libraries, such as support for 3D meshes and scenes, and enabling efficient rendering that responds to user and device motion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional low-level 3D graphics libraries like OpenGL or Direct3D are used, then basic 3D rendering is supported, but the rendering performance and detail level are insufficient for head-tracking based UIs

Engineering Contradiction:

Improve3D graphical element detail levelVSAvoidrendering speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The system separates the 3D rendering function from the UI framework by introducing an independent 3D rendering engine. This segmentation allows each component to be optimized independently - the rendering engine for high-performance 3D graphics while the UI framework maintains its responsiveness and integration capabilities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary 3D rendering engine that sits between the UI framework and the display output. This intermediary handles all 3D rendering operations, allowing the UI framework to remain simple and responsive while the rendering engine provides high-performance, detailed 3D graphics through advanced techniques like hardware acceleration and optimized rendering pipelines.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If built-in 3D graphics libraries are used, then integration with the operating system is straightforward, but the latency is too high for responsive head-tracking interfaces

Engineering Contradiction:

ImproveUI responsivenessVSAvoidrendering latency

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The rendering system implements dynamic rendering where the 3D scene is updated and re-rendered in real-time based on head-tracking data. The independent rendering engine can dynamically adjust rendering parameters, update frequencies, and scene transformations to match the user's head movements, providing responsive feedback without the latency of conventional libraries.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary actions by pre-processing 3D scene data, pre-calculating transformations, and maintaining ready-to-render scene graphs. This allows the rendering engine to quickly respond to head-tracking input without requiring extensive computation at the moment of rendering, thereby reducing latency.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If an independent 3D rendering engine is integrated with the UI framework, then highly detailed and interactive 3D elements are achieved, but the system complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The independent 3D rendering engine is designed as a universal component that can render various types of 3D content (meshes, scenes, models) and integrate with standard UI frameworks. It provides multiple functions including hardware-accelerated rendering, scene graph management, and head-tracking responsiveness, making it adaptable to different 3D UI requirements while maintaining a single integrated architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If conventional rendering approaches are used, then system simplicity is maintained, but immersive 3D experiences cannot be provided

Engineering Contradiction:

Improveimmersive experience qualityVSAvoidrendering system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces conventional software-based 3D rendering with a specialized rendering engine that utilizes hardware acceleration (GPU). This substitution provides significantly higher rendering performance and visual quality for immersive 3D experiences, while the rendering engine is designed to be integrated with the UI framework to manage system complexity.

Inventive Principle:

AI summary

Systems and approaches provide for a user interface (UI) that is based on the position of a user's head with respect to a computing device. In particular, a three-dimensional (3D) rendering engine that is independent of a particular operating system can be integrated with the UI framework of the operating system such that a window or view into a fully 3D world can be drawn using the independent renderer. This window or view can then be laid out and manipulated in a manner similar to other elements of the UI framework. Further, the 3D window or view can be configured to monitor head tracking data as input events to the UI framework. The contents of the window or view can be redrawn or rendered based on the head tracking data to simulate three-dimensionality of the content.
