Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fixed cursor speed or sensitivity is used, then device complexity is reduced, but cursor movement efficiency and accuracy deteriorate

Engineering Contradiction:

Improvecursor movement efficiencyVSAvoidcontrol system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic cursor speed adjustment by detecting user head orientation and eye movements through a camera, then automatically modifying cursor control parameters in real-time based on detected user intent, eliminating the need for manual reconfiguration while adapting to different tasks and applications

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs self-configuration by automatically detecting user intent through head pose and eye tracking, then autonomously adjusting cursor speed and sensitivity parameters without requiring user intervention, making the system adapt to user needs independently

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If fixed cursor speed is used, then ease of operation is maintained, but adaptability to different applications deteriorates

Engineering Contradiction:

Improveapplication-specific optimizationVSAvoiduser configuration effort

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically detects which application is active and adjusts cursor parameters accordingly without user input, performing self-configuration for different gaming applications and productivity software based on detected user intent and application context

Inventive Principle:

Principle #25Self-service

AI summary

Systems and methods are provided for implementing adaptive cursor control. One system may include a camera to detect an image data stream including a feature of a user. The system may also include an electronic processor to detect, via a feature tracking model that receives the image data, a change in a position of the feature. The electronic processor may also, in response to detecting the change in the position of the feature, determine a control parameter for a cursor displayed to the user. The electronic processor may also control the cursor displayed to the user using the control parameter.
