Timestamp-Based Collaborative Object Access in AR Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality and augmented reality technologies lack efficient methods for collaborative sessions that allow selective access to collaborative objects and virtual content based on timestamped durations, limiting user interaction and content management.
Innovation Solution
A collaborative session system that associates timestamps with user requests for accessing collaborative objects, providing editing access within a specified duration and viewing access after, using advanced AR technologies like computer vision and object tracking to enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If collaborative tools enable users to virtually meet and communicate in a virtual setting, then user interaction and collaboration capability are improved, but access control and content management become more complex
Solution Approach 1:
The system performs preliminary actions by assigning timestamps to users upon their first access to a collaborative object and establishing a collaborative duration period in advance. This preliminary setup enables automatic access control decisions without requiring complex real-time negotiations or manual permissions management, thus resolving the contradiction between collaboration versatility and access control complexity.
Solution Approach 2:
The patent implements dynamic access control where user permissions automatically transition from editing access to viewing access based on the passage of time relative to the collaborative duration period. This dynamic mechanism simplifies access control by replacing static permission settings with time-based automatic transitions, addressing the contradiction between collaboration flexibility and access control complexity.
2Productivity
If editing access is provided to all users during the collaborative period, then user contribution and content creation are improved, but content integrity and unauthorized modifications increase
Solution Approach 1:
The system performs preliminary action by establishing a collaborative duration period and assigning timestamps before the collaboration begins. This allows the system to automatically manage access transitions, enabling unrestricted editing during the collaborative period while automatically transitioning to viewing-only mode afterward, thus maintaining content integrity without compromising creation efficiency.
Solution Approach 2:
The patent implements periodic action by dividing access into distinct time periods: a collaborative period with editing access followed by a viewing period with read-only access. This periodic structure ensures high productivity during the collaborative phase while guaranteeing content integrity during the subsequent viewing phase, resolving the contradiction between content creation efficiency and content integrity.
3Reliability
If viewing access is restricted only to users with editing access, then content security is improved, but user experience and accessibility deteriorate
Solution Approach 1:
The system applies dynamic access control where permissions automatically transition from editing to viewing based on the user's timestamp relative to the collaborative duration period. This dynamic mechanism ensures that users who joined during the collaborative period automatically gain viewing access after the period ends, improving accessibility while maintaining security through automatic timestamp verification.
Solution Approach 2:
The patent implements feedback by continuously monitoring the current time against the collaborative duration period and automatically adjusting user permissions accordingly. This feedback mechanism ensures that users receive appropriate access levels (editing during collaboration, viewing after collaboration) without manual intervention, balancing content security with user accessibility.
4Measurement precision
If manual permission management is used for collaborative objects, then access control precision is improved, but system complexity and administrative overhead increase
Solution Approach 1:
The system enables self-service by automatically managing access control based on timestamps and the collaborative duration period. Users do not require manual permission assignments; instead, the system autonomously determines whether to grant editing or viewing access by comparing the user's timestamp with the collaborative period, achieving precise access control without increasing system complexity.
Solution Approach 2:
The patent applies parameter changes by using the timestamp parameter and collaborative duration period parameter to automatically determine access permissions. This parameter-based approach replaces complex manual permission management with simple time-based calculations, maintaining access control precision while significantly reducing system complexity and administrative overhead.
Data Source
AI summary
Collaborative sessions in which access to added virtual content is selectively made available to participants/users by a collaborative system. The system receives a request from a user to join a session, and associates a timestamp with the user corresponding to receipt of the request. Users can edit the collaborative object if the timestamp is within the collaborative duration period and can view the collaborative object if the timestamp is after the collaborative duration period.
