Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion sensing hardware and complex motion detection calculations are used in existing motion controllers, then motion tracking capability is improved, but device complexity and development difficulty increase
Solution Approach 1:
The patent introduces an intermediary translation layer that converts complex motion sensor data into simple keyboard commands. The motion sensing module detects user motions, and the input command translation module acts as a mediator to translate these motions into standardized keyboard input commands based on predetermined motion-command mapping relationships, shielding game developers from complex motion detection calculations while maintaining accurate motion tracking capability.
Solution Approach 2:
The patent replaces the complex mechanical system of motion detection and calculation with a standardized keyboard command interface. Instead of requiring developers to implement motion sensing algorithms, the system substitutes this complex mechanism with a simple keyboard protocol that maps predetermined motions to standard keyboard commands, significantly reducing development complexity while preserving motion tracking functionality.
2Ease of operation
If standardized keyboard commands are used instead of custom motion detection, then ease of operation for developers is improved, but motion control precision may be reduced
Solution Approach 1:
The patent changes the parameter representation from complex motion vectors and calculation results to standardized keyboard command parameters. By mapping predetermined motions to specific keyboard commands based on motion characteristics (such as direction, intensity, and duration), the system maintains sufficient precision for game control applications while using simple, standardized parameters that are easy for developers to implement.
3Measurement precision
If motion sensing module with multiple sensors is used, then motion detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent makes the motion sensing module universal by designing it to work with various types of motion sensors (accelerometers, gyroscopes, inclinometers, analogue switches, digital switches) through a unified interface. The input command translation module handles different sensor types and configurations, allowing the same basic architecture to achieve accurate motion detection across multiple sensor implementations without increasing overall system complexity.
