Solution Overview

Problem

Conventional virtual rendering systems fail to provide engaging and entertaining augmented reality experiences due to environmental conditions, user actions, and unanticipated visual interruptions, often rendering static templates that do not adapt to contextual information.

Innovation Solution

A virtual rendering system that utilizes contextual information to determine stylizations and behaviors of virtual objects, incorporating multiple redundant tracking systems to maintain consistent rendering in 3D spaces, and employs a surface-aware lens for anchoring objects to real-world surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional virtual rendering systems use basic static templates, then the system complexity is reduced, but the adaptability to contextual information deteriorates

Engineering Contradiction:

Improveadaptability to contextual informationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transitioning from static templates to dynamic virtual objects that automatically adapt their appearance and behavior based on real-time contextual information. The system dynamically adjusts object properties such as color, texture, and animation based on detected environmental conditions, user actions, and temporal data, enabling the rendering system to respond adaptively to changing contexts without requiring manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements parameter changes by modifying virtual object properties based on contextual parameters detected from the environment. When contextual information changes (e.g., time of day, weather conditions, user interactions), the system changes corresponding parameters of the virtual objects such as color, size, or animation state, allowing the same template to produce different visual representations adapted to specific contexts.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If multiple redundant tracking systems are implemented, then the reliability of rendering maintenance is improved, but the device complexity increases

Engineering Contradiction:

Improverendering consistency under interruptionsVSAvoidtracking system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies beforehand cushioning by implementing multiple redundant tracking systems that prepare alternative tracking methods in advance. When one tracking system fails due to environmental conditions or visual interruptions, the system can switch to backup tracking mechanisms without disruption, cushioning against the harmful effects of tracking failures and maintaining continuous reliable rendering.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system changes tracking parameters by switching between different tracking methods based on environmental conditions and detection success. The system monitors the effectiveness of each tracking system and dynamically adjusts which tracking method is active, changing parameters such as tracking accuracy, response time, and method selection to optimize reliability under varying conditions.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If dynamic contextual rendering is implemented, then the adaptability and engagement of augmented reality experiences is improved, but the processing time and energy consumption increase

Engineering Contradiction:

Improvecontextual adaptabilityVSAvoidprocessing energy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by selectively processing and rendering only the necessary portions of contextual information and virtual objects based on current needs. The system determines which contextual parameters are relevant to the current scene and user view, processing only those aspects rather than analyzing all possible environmental data, thereby reducing unnecessary energy consumption while maintaining adequate adaptability.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system implements periodic action by updating virtual object rendering at appropriate intervals rather than continuously. The system adjusts rendering frequency based on changes in contextual information, updating objects only when significant contextual changes occur or at optimized time intervals, reducing processing energy consumption compared to continuous real-time rendering while maintaining adaptability to contextual changes.

Inventive Principle:

Principle #19Periodic action

AI summary

Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program and a method for rendering a virtual object in a real-world environment depicted in image content based on contextual information. A virtual object template is selected. One or more stylizations for the virtual object template are determined based on contextual information associated with a computing device. A virtual object is generated by applying the one or more stylizations to the virtual object template. The virtual object is rendered within a 3D space captured within a camera feed of the computing device.
