Projection-Based AR Surface Selection and Content Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented-reality systems lack the ability to provide seamless and privacy-conscious integration of social networking data within an in-the-world experience, failing to adapt content dynamically based on user interactions and environment changes while respecting user privacy settings.
Innovation Solution
A projection-based augmented-reality system that includes interaction devices with visual and audio output, sensor devices, and controller modules, which model indoor environments, track user activities, and adapt content projection based on sensor data, leveraging social networking data only with explicit user permission and adhering to privacy settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the augmented-reality system accesses social networking data to enhance user experience, then the personalization and relevance of projected content is improved, but user privacy protection deteriorates
Solution Approach 1:
The patent introduces a privacy manager as an intermediary component that mediates between the augmented-reality system and social networking data. This privacy manager obtains user consent, anonymizes personal information, and controls data access permissions, allowing the system to leverage social networking data for personalized content while protecting user privacy through multiple layers of abstraction and control mechanisms.
2Speed
If the system dynamically adapts content based on real-time sensor data and user interactions, then the user experience responsiveness is improved, but the system complexity increases
Solution Approach 1:
The patent segments the augmented-reality system into distinct functional modules: environment sensors for data collection, privacy manager for data processing, content adapter for content modification, and projector for display. Each module operates independently with well-defined interfaces, enabling real-time content adaptation while managing system complexity through modular design that allows independent development, testing, and maintenance of each component.
3Adaptability or versatility
If the augmented-reality system projects content onto diverse surfaces in varying environments, then the versatility of the system is improved, but the projection quality consistency deteriorates
Solution Approach 1:
The patent implements dynamic surface characterization and content adaptation mechanisms. The system continuously scans and characterizes projection surfaces using environment sensors, detecting variations in surface texture, color, curvature, and lighting conditions. Based on real-time surface analysis, the content adapter dynamically adjusts projection parameters including image distortion correction, brightness compensation, and color calibration, ensuring consistent projection quality across diverse surfaces and environmental conditions.

AI summary
A method includes retrieving a media content item for display to a user in an environment. The method includes receiving, from one or more interaction devices each including a projector and a camera, one or more media objects captured by one or more cameras, where one or more of the media objects include images of the user, and determining a location of the user in the environment based on an analysis of the one or more of the media objects. The method also includes identifying one of the interaction devices based on the determined location of the user and sending, to the identified interaction device, the media content item and instructions causing the projector associated with the identified interaction device to project the media content item.
