Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple touch-sensitive panels and inertial sensors are integrated into the handheld device, then the versatility and functionality of user interactions are improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple touch-sensitive panels (first and second touch-sensitive panels) with inertial measurement units into a unified gesture recognition system. The processor integrates signals from all these components to detect complex gestures, enabling versatile user interactions while managing the complexity through coordinated operation of existing components.
Solution Approach 2:
The gesture recognition system serves multiple functions: it can detect various types of gestures (single touch, multi-touch, sliding, tapping), identify user intentions, and trigger different macros or tasks. This multi-functionality approach allows the same hardware components to handle diverse interaction modes, improving versatility without proportionally increasing complexity.
2Ease of operation
If gesture-based macro execution is implemented, then the ease of operation is improved by reducing the number of steps required, but the difficulty of detecting and measuring gestures accurately increases
Solution Approach 1:
The gesture detection process is segmented into distinct phases: detecting the first gesture that initiates macro mode, monitoring for the second gesture within a time window, and executing the corresponding macro. This segmentation allows the system to handle complex gesture sequences systematically, making accurate detection more manageable while presenting simple operation to the user.
Solution Approach 2:
The system performs preliminary actions by establishing a time window parameter when the first gesture is detected. This pre-configured time window guides subsequent gesture detection, helping to filter out spurious inputs and focus on relevant second gestures. This preliminary setup simplifies the overall detection process while maintaining ease of operation.
