Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual object is added to a real-time photographed image using conventional augmented reality methods, then the virtual object can be displayed in the current location, but the user cannot interact with the same virtual object in different places or share the AR experience across different locations
Solution Approach 1:
The patent extracts spatial information (location coordinates, orientation data, depth information) from the real-time photographed image and separates it from the visual content. This extracted spatial context is stored independently, allowing the virtual object to be repositioned and interacted with in different locations while maintaining the original spatial relationships, thus enabling location-independent AR experiences
Solution Approach 2:
The system performs preliminary action by capturing and storing spatial information about the environment and object positions before the user moves to different locations. This pre-captured spatial data includes coordinate systems, depth maps, and orientation information that are saved and later used to reconstruct the AR scene in new locations, enabling seamless cross-location interaction without requiring real-time presence in the original location
2Adaptability or versatility
If spatial information is mapped and stored for each image section to enable location-independent AR, then users can interact with virtual objects in different places, but the system complexity increases due to processing and managing spatial data from multiple image sections
Solution Approach 1:
The patent divides the photographed image into multiple image sections and processes spatial information for each section independently. Each image section has its own mapped spatial data including location coordinates and orientation information. This segmentation allows the system to manage complex spatial data in smaller, more manageable units, reducing the overall system complexity while maintaining cross-location AR capability
Solution Approach 2:
The system introduces an intermediary spatial information mapping layer that translates real-world spatial relationships into a standardized digital representation. This intermediary layer includes coordinate transformation algorithms and spatial data structures that mediate between the physical environment and the virtual objects, simplifying the complexity of managing spatial information across multiple image sections and locations

AI summary
An electronic device is provided. The electronic device includes: a display; a camera; a memory; and a processor configured to identify a video captured in real time through the camera as a plurality of image sections, obtain spatial information corresponding to each image section, map the obtained spatial information to each of the plurality of image sections and store same in the memory, and control the display to add a virtual object image to the video and display the same on the basis of the spatial information mapped to each of the plurality of image sections when a user command for adding the virtual object image to the video is input.
