Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective solutions for synchronizing and sharing personalized augmented reality content between devices, failing to provide tailored information based on user preferences and interfering with the primary content viewing experience.
Innovation Solution
A content synchronization apparatus and method that includes a communication unit, control unit, and output unit to share and synchronize content, state information, and augmented information between devices, using user profile and preference information to filter and display relevant data, while allowing playback control and executing applications concurrently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented information is overlaid on the display screen during content playback, then the information richness and interactivity are improved, but the viewing experience is deteriorated due to interference with primary content
Solution Approach 1:
The display controller dynamically adjusts the transparency and visibility of augmented information based on user interaction state. When no interaction is detected, the augmented information becomes transparent or hidden to avoid interfering with content viewing. When user interaction is detected (e.g., touch, gaze, or command input), the augmented information becomes fully visible and interactive, thus resolving the contradiction between information richness and viewing experience.
Solution Approach 2:
Instead of displaying all augmented information simultaneously, the system selectively displays only the most relevant portion based on context, user preferences, and current interaction state. This partial display approach provides sufficient information richness while minimizing visual clutter and interference with the primary content viewing experience.
2Adaptability or versatility
If content synchronization is implemented between multiple devices, then the sharing capability is improved, but the system complexity is deteriorated
Solution Approach 1:
A centralized server acts as an intermediary to manage content synchronization between multiple devices. The server receives content from one device, processes it, and distributes it to other devices. This mediator approach enables content sharing across multiple devices while keeping individual device complexity low, as each device only needs to communicate with the server rather than implement complex peer-to-peer synchronization protocols.
Solution Approach 2:
The synchronization system is designed to work with multiple types of devices (mobile phones, tablets, computers, televisions) and multiple content formats through a universal interface. The server implements multi-functional capabilities to handle different device types, communication protocols, and content formats, thereby enabling broad content sharing capability while maintaining a relatively simple client-side implementation on each device.
3Loss of information
If personalized augmented information is provided based on user profile, then the information relevance is improved, but the data processing complexity is deteriorated
Solution Approach 1:
User profile information and preferences are collected and processed in advance, before actual content interaction. The server pre-processes user data to create personalized information filters and preferences. When content is synchronized and augmented information is generated, the pre-processed user profile data is quickly applied to select and filter relevant information, thereby achieving high information relevance without requiring complex real-time processing during content playback.

AI summary
A content synchronization apparatus is provided. The content synchronization apparatus includes a communication unit configured to communicate with a device that the content synchronization apparatus can synchronize content with, a control unit configured to, in response to a synchronization command to share current content being played by the device being received, share the current content by acquiring the current content and state information corresponding to the current content through the communication unit, synchronize the current content with the device using the current content and the state information, and configure a display screen based on the results of the synchronization of the current content with the device, and an output unit configured to display the configured display screen.
