Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional input devices (keyboards, mice, wired controllers) are used for motion gaming, then the gaming system can capture basic user inputs, but the user experience is degraded due to prolonged sitting and finger control, and health is adversely affected
Solution Approach 1:
The patent replaces conventional mechanical input devices (keyboards, mice, wired controllers) with a motion sensing system that uses sensors (accelerometer, gyroscope, magnetometer) to detect body movements. This substitution eliminates the need for prolonged sitting and finger control, allowing users to stand and move naturally while playing games, thereby improving user experience and eliminating health负面影响
Solution Approach 2:
The patent introduces a motion sensing device as an intermediary between the user's body movements and the game console. This intermediary captures subtle movements through sensors and transmits the data to the game system, enabling natural body movement control without direct hand-held device manipulation, thus resolving the contradiction between ease of operation and health impact
2Measurement precision
If existing motion gaming input devices (game controllers, cameras, mobile phones) are used, then the system can capture some user movements, but subtle movements cannot be captured accurately, leading to unsatisfactory realism degree
Solution Approach 1:
The patent combines multiple sensing technologies (accelerometer for linear acceleration, gyroscope for angular velocity, magnetometer for orientation) into an integrated motion sensing system. This merging of sensors enables accurate capture of subtle movements across multiple dimensions, significantly improving measurement precision and realism degree compared to single-sensor or camera-based systems
Solution Approach 2:
The motion sensing device is designed to be universally applicable for capturing various types of movements (subtle hand movements, body gestures, orientation changes) across different gaming scenarios. The multi-functional sensor system can detect different movement types with high precision, enhancing adaptability and realism degree simultaneously
3Ease of operation
If users hold an input device in the hand for motion gaming, then the system can receive user inputs, but the user's natural movements are affected and degraded, reducing the sport experience realism
Solution Approach 1:
The patent replaces hand-held mechanical input devices with a wearable motion sensing device that captures movements passively. The device uses sensors to detect body movements without requiring the user to actively manipulate controls, maintaining movement freedom while ensuring accurate movement capture through multi-axis sensor data
4Loss of information
If conventional game controllers are used, then the system can capture gross movements, but subtle movements are not captured, leading to loss of information about user intent
Solution Approach 1:
The patent merges multiple sensing capabilities (accelerometry, gyroscopy, magnetometry) into a single integrated motion sensing device. This combination enables comprehensive capture of subtle movements without proportionally increasing device complexity, as the sensors work together in a unified system with centralized processing
Solution Approach 2:
The motion sensing device acts as an intermediary that captures subtle movement information and translates it into meaningful game control signals. The device includes processing circuitry that filters and interprets sensor data, reducing information loss while managing system complexity through intelligent data processing

AI summary
A smart watch and motion gaming system are disclosed. The smart watch interacts with the motion-controlled game apparatus, and includes a controller, and a geomagnetic field sensor, a gravity sensor, a gyroscope, and a data transmission circuit, which are electrically connected to the controller. The geomagnetic field sensor detects an orientation of the smart watch and acquires the orientation data. The gravity sensor detects an inclination condition of the smart watch and acquires the inclination data. The gyroscope detects a rate of rotation of the smart watch to acquire the rotation rate data. The controller runs at least one of the geomagnetic field sensor, the gravity sensor, and the gyroscope in response to the user's selection, and accordingly collect the sensing data. The data transmission circuit transmits the collected sensing data to the motion-controlled game apparatus.
