Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users interact with virtual objects through traditional AR interaction technologies, then basic interaction functions are provided, but the efficiency and effect of interaction are insufficient leading to suboptimal user experience
Solution Approach 1:
The virtual object is divided into multiple components that can be independently manipulated and assembled. Users interact with individual components rather than the entire object, enabling more precise and efficient interaction. The system segments the assembly process into discrete steps where users can place and adjust each component separately before final assembly.
Solution Approach 2:
A virtual guide or indicator is introduced as an intermediary element to assist users in the assembly process. This guide provides visual feedback and directional cues that mediate between the user's actions and the virtual object assembly, improving interaction efficiency by clearly indicating where components should be placed and how they should be oriented.
2Adaptability or versatility
If multiple components of a virtual object are displayed and assembled in an AR scene, then interactive assembly capability is enhanced, but the complexity of rendering and maintaining visual consistency increases
Solution Approach 1:
The system pre-calculates and pre-positions the components of the virtual object in the AR scene before user interaction begins. Component placement positions, orientations, and transformation matrices are determined in advance based on the target object's geometry, reducing the computational complexity during the actual assembly process.
Solution Approach 2:
The system continuously monitors the positions and orientations of virtual components relative to the target object and provides real-time feedback through visual indicators. This feedback mechanism guides users to achieve correct assembly without requiring complex rendering calculations, as the system actively adjusts and indicates the correct state rather than relying solely on user precision.
3Measurement precision
If the rendering of virtual components is updated based on user device posture changes, then visual accuracy and immersion are improved, but the computational load and processing time increase
Solution Approach 1:
The rendering update system operates periodically at optimized intervals rather than continuously responding to every minor device movement. The system triggers rendering updates based on significant posture changes detected through sensors, reducing unnecessary processing while maintaining visual accuracy. This periodic update mechanism balances precision with computational efficiency.
Solution Approach 2:
The rendering system dynamically adjusts its update frequency and complexity based on the current interaction state and device movement intensity. During stable viewing conditions, updates are less frequent; during active manipulation or rapid device movement, updates increase in frequency. This dynamic adaptation optimizes the balance between visual accuracy and processing time.

AI summary
In a method for augmented reality (AR) interaction, indication information of a target object and one or more components (406-410, 506, 508, 510, 512, 514) of the target object are displayed in an AR scene (150, 400, 500) displayed by a user device (110). In response to a change in a posture of the user device (110), rendering of the one or more components (406-410, 506, 508, 510, 512, 514) is updated in the AR scene (150, 400, 500). In response to the updated one or more components (406-410, 506, 508, 510, 512, 514) visually matching the indication information, the target object is displayed as an entirety in the AR scene (150, 400, 500). According to this method, a user can flexibly control one or more components (406-410, 506, 508, 510, 512, 514) in the AR scene (150, 400, 500) by changing the posture of the device, so that they visually match and finally are assembled into a target object. The interaction experience and the interest of the user in the AR scene can be improved.
