Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If XR devices use traditional interaction methods (eye movement detection, gesture detection, hand shaking), then the system can operate with simple hardware, but the interaction speed and accuracy are low
Solution Approach 1:
The patent replaces traditional mechanical interaction methods (eye movement detection, gesture detection, hand shaking) with an inertial measurement unit (IMU) based system. The IMU uses microelectromechanical systems (MEMS) technology to detect device orientation and movement, enabling faster and more accurate cursor control without relying on slow mechanical gestures or eye tracking mechanisms.
Solution Approach 2:
The patent changes the detection parameters from qualitative gestures and eye movements to quantitative inertial data (acceleration, rotation rates, orientation angles). By measuring physical parameters such as device tilt angle and acceleration vectors, the system achieves higher interaction speed and accuracy while maintaining relatively simple hardware architecture.
2Measurement precision
If XR devices use traditional interaction methods (eye movement detection, gesture detection, hand shaking), then the hardware structure can remain simple, but the interaction accuracy is low
Solution Approach 1:
The patent replaces imprecise mechanical interaction methods with an IMU-based detection system that provides high-precision measurement of device orientation and movement. The IMU's ability to accurately measure angular velocity, acceleration, and orientation enables precise cursor control and interaction, significantly improving measurement precision without adding complex mechanical structures.
Solution Approach 2:
The system uses the terminal device itself as the input controller, eliminating the need for separate control mechanisms. The device's own motion and orientation, detected by the IMU, directly control the cursor and interaction elements, providing high accuracy while keeping the system architecture simple and self-contained.
3Adaptability or versatility
If XR devices implement multiple input functions (IMU, touch, key input), then the versatility and user experience improve, but the system complexity increases
Solution Approach 1:
The patent implements a universal input system where a single terminal device serves multiple interaction functions. The device can operate as an IMU controller for motion-based input, a touch screen for direct contact input, and a keyboard for text input, all through one integrated system. This multi-functionality approach increases versatility without proportionally increasing complexity, as the same hardware platform supports multiple input modes.
Solution Approach 2:
The system dynamically switches between different input methods based on user needs and context. The terminal device can transition between IMU control mode, touch input mode, and keyboard input mode, allowing the system to adapt to different interaction scenarios. This dynamic flexibility provides versatile input options while maintaining a relatively simple underlying architecture that can activate different functions as needed.

AI summary
A method of extended reality (XR) operation for improving operation experience applied in an XR operation system includes a terminal device and an XR device. The terminal device establishes a communication connection with the XR device after a started predefined program. The XR device transmits an Inertial Measurement Unit (IMU) switched-on instruction, which indicates that an IMU function is started, to the terminal device in response to starting the IMU function. The terminal device acquires IMU data and transmits the IMU data to the XR device in response to the touch switched-on instruction. The XR device receives the IMU data, displays a cursor, and controls a movement of the cursor based on the IMU data. A method of XR operation is also provided.
