Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users interact with virtual objects in mid-air using whole arm motions, then virtual button pressing and object manipulation become possible, but physical discomfort and pain occur due to prolonged arm movement
Solution Approach 1:
The patent introduces eye tracking technology as an intermediary input method. Instead of requiring whole arm motions to interact with virtual objects, the system uses eye movement detection to capture user intent. The eye tracker detects gaze direction and duration to infer selection and interaction commands, eliminating the need for prolonged arm movements while maintaining virtual object manipulation capability.
Solution Approach 2:
The patent replaces the mechanical arm movement system with an optical-based eye tracking system. By substituting physical arm motions with eye gaze detection, the system eliminates the physical strain associated with prolonged arm usage. The eye tracker uses optical sensors to detect eye position and movement, converting biological eye movements into digital interaction signals.
2Speed
If virtual objects are displayed at fixed sizes and positions, then rendering is simple and fast, but users cannot clearly recognize the sense of distance to virtual objects in AR environment
Solution Approach 1:
The patent implements dynamic scaling of virtual object sizes based on their distance from the user. As virtual objects are positioned at different depths in the AR scene, their displayed sizes automatically adjust to maintain proper perspective relationships. This dynamic size adaptation occurs in real-time as the user moves or as virtual objects are repositioned, preserving both rendering efficiency and accurate distance perception.
Solution Approach 2:
The patent changes the display parameters (size, position, scale) of virtual objects based on their spatial distance from the user. The system calculates distance metrics and applies corresponding scaling factors to virtual object dimensions. This parameter adjustment maintains the illusion of depth and realistic spatial relationships without requiring complex rendering computations.
3Adaptability or versatility
If workspace customization requires selecting and arranging virtual objects manually, then users can create personalized workspaces, but the process consumes a lot of time and effort
Solution Approach 1:
The patent implements automatic workspace layout generation that performs preliminary arrangement of virtual objects based on detected real-world surfaces and spaces. When a user enters a new environment, the system automatically identifies suitable display surfaces (tables, walls, windows) and pre-arranges virtual objects according to the detected spatial configuration. This preliminary automatic arrangement significantly reduces the manual setup time while preserving full customization options for later adjustment.
Solution Approach 2:
The patent enables the workspace system to automatically adapt to the user's environment without requiring manual configuration. The system detects real-world surfaces, calculates optimal placement positions, and automatically positions virtual objects based on spatial relationships. This self-service capability allows the workspace to customize itself to the environment, eliminating the need for users to manually select and arrange each virtual object.
4Use of energy by moving object
If all information is reset when device is shut down, then system resources are freed, but user-customized workspace settings are lost causing inconvenience
Solution Approach 1:
The patent implements preliminary saving of workspace configuration data to persistent storage before the device shuts down. The system automatically saves the detected spatial information, virtual object positions, and customization settings to memory or cloud storage. This preliminary save operation ensures that workspace settings are preserved across device restarts without requiring additional user actions or consuming excessive resources during normal operation.
