Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile device embedded cameras are used, then convenience and portability are improved, but important moments are not captured due to quick occurrence or user forgetfulness
Solution Approach 1:
The wearable device automatically detects gestures and triggers camera operations without requiring manual user input. The system serves itself by using its own sensors to detect user intent and automatically capture moments, eliminating the need for users to manually operate the camera while ensuring important moments are captured.
Solution Approach 2:
The device uses depth sensors and cameras to continuously monitor the environment and user gestures, providing real-time feedback to determine when to capture images or video. This feedback mechanism ensures that spontaneous moments are captured automatically based on detected gestures or events.
2Ease of operation
If smart glasses are used, then hands-free operation is improved, but users are detached from their environment
Solution Approach 1:
Instead of requiring users to look at displays or screens, the system projects images and information onto surfaces in the user's environment. This copying approach allows users to interact with digital content while maintaining awareness of their physical surroundings, eliminating environmental detachment while preserving hands-free operation.
Solution Approach 2:
The system transitions from traditional 2D screen displays to 3D spatial projection onto environmental surfaces. This dimensional change allows information to be presented in the user's physical space rather than requiring visual focus on a device screen, maintaining environmental awareness while enabling hands-free interaction.
3Ease of operation
If laser projection system is added, then intuitive interface and interaction are improved, but device complexity increases
Solution Approach 1:
The wearable device integrates multiple functions including gesture recognition, camera capture, depth sensing, and laser projection into a single platform. This multi-functionality allows the system to provide an intuitive projected interface while managing overall device complexity through shared hardware and software resources.
Solution Approach 2:
The laser projection system acts as an intermediary between the user and the digital content, projecting information onto environmental surfaces rather than requiring direct interaction with device screens or buttons. This intermediary approach simplifies user interaction while the complexity is managed through integrated control systems.
