Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gaze-based control is implemented for external devices, then user convenience and ease of operation improve, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture gaze direction information. The camera serves as a mediator between the user's gaze and the control system, converting physical gaze movements into digital signal inputs that can be processed to control external devices without direct physical contact.
Solution Approach 2:
The patent replaces traditional mechanical interaction methods (physical touch, buttons, knobs) with an optical/electromagnetic system. Instead of requiring mechanical contact with the device, users can control external devices through gaze direction captured by the camera and processed through software algorithms.
2Adaptability or versatility
If augmented reality display is used to show control interfaces, then user experience and adaptability improve, but manufacturing precision and device complexity increase
Solution Approach 1:
The patent implements a universal control interface that can interact with multiple types of external devices (smartphones, tablets, computers, televisions) through a single augmented reality display system. The display can dynamically adapt its content based on the detected external device and gaze direction, providing a multi-functional control mechanism that works across different device types.
Solution Approach 2:
The augmented reality display dynamically adjusts its content and characteristics based on real-time gaze detection and the detected external device. The interface transitions from static to dynamic, adapting its appearance and functionality according to user gaze position and the target device being controlled.
3Speed
If real-time gaze tracking is implemented, then responsiveness and ease of operation improve, but energy consumption and device complexity increase
Solution Approach 1:
Instead of continuous gaze tracking, the system employs periodic sampling of gaze direction at predetermined time intervals. The camera captures gaze information periodically rather than continuously, reducing the computational load and energy consumption while maintaining sufficient responsiveness for natural interaction.
Solution Approach 2:
The system utilizes the existing camera infrastructure of the wearable device to perform gaze tracking, leveraging the camera's natural capabilities rather than requiring dedicated expensive gaze tracking hardware. This self-service approach reduces overall system complexity and energy requirements.
