Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional screen-based interaction methods are used with three-dimensional virtual objects, then the interaction method is simple to implement, but the interaction capability is limited and does not meet user requirements
Solution Approach 1:
The patent transitions from traditional two-dimensional screen-based interaction to three-dimensional spatial interaction by projecting virtual objects into a three-dimensional display region. Users can interact with virtual objects from multiple angles and positions in space, not just from a fixed frontal view on a screen. This dimensional expansion enables richer interaction capabilities including spatial manipulation, multi-angle observation, and immersive engagement.
Solution Approach 2:
The patent introduces a projection system as an intermediary between the user and the virtual objects. The projection device maps virtual objects onto a three-dimensional display region, creating a mediator that enables natural spatial interaction. This intermediary layer allows users to interact with virtual objects using natural hand gestures and body movements in physical space, bridging the gap between digital virtual objects and physical user actions.
2Ease of operation
If motion sensing interaction is added to enable users to interact with three-dimensional virtual objects in space, then the user experience is enhanced, but the device complexity increases
Solution Approach 1:
The system employs motion sensing technology to automatically detect and track user gestures and positions in the three-dimensional space without requiring explicit commands or complex control interfaces. The motion sensing module continuously monitors user movements and automatically translates them into interaction operations on the virtual objects, enabling intuitive and effortless interaction. Users simply perform natural movements, and the system self-adapts to their actions.
Solution Approach 2:
The patent implements a feedback mechanism where the system responds to user motion sensing inputs by updating and re-projecting the virtual objects in real-time. When users perform gestures or move within the interaction space, the system detects these movements and provides immediate visual feedback by modifying the virtual objects' state or position in the three-dimensional display region, creating a responsive and engaging interaction loop.

AI summary
This application discloses an interaction method performed by a computer device. A three-dimensional virtual object is obtained; an optical signal of the virtual object is transmitted to a first side of an optical panel and then projected from the first side into a second side of the optical panel through the optical panel, so that an image of the virtual object is generated on the second side of the optical panel via negative refraction; when it is detected that a user performs a motion sensing operation on the image of the three-dimensional virtual object, updating the three-dimensional virtual object based on the motion sensing operation, to obtain an updated three-dimensional virtual object.
