Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR systems require manual operation of control devices for content adjustment, which is complex and inefficient.
Innovation Solution
A VR device with a navigation control system that allows users to adjust content by changing their gaze point, determining initial and moving positions, and adjusting object content based on these positions, enabling intuitive and efficient control through gaze direction changes.

Engineering Contradiction Analysis
1Ease of operation
If manual operation of control device is used to adjust target content, then control precision can be achieved, but operation complexity increases and efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical control operations with eye-tracking technology. The control unit detects eye movement signals and converts them into navigation commands, substituting the mechanical control device operation with an optical/biological sensing system. This allows users to adjust virtual content by simply moving their eyes, eliminating the need for manual manipulation of control devices while maintaining precise control capability.
Solution Approach 2:
The system uses the user's natural eye movements as the control input, making the control mechanism self-service in nature. The eye-tracking system automatically detects and interprets gaze direction and eye movement patterns without requiring the user to learn or operate external controls. The navigation control is dynamically generated based on eye position, creating an intuitive and automatic interaction paradigm.
2Ease of operation
If eye tracking technology is implemented, then operation simplicity improves, but system complexity increases
Solution Approach 1:
The control unit performs multiple functions: it manages VR rendering, processes eye-tracking data, generates navigation controls, and adjusts virtual content based on gaze patterns. By consolidating these diverse functions into a single control unit, the patent reduces overall system complexity despite incorporating eye-tracking technology. The navigation control mechanism serves as a universal interface for various VR interactions.
Solution Approach 2:
The patent merges the eye-tracking detection function with the navigation control generation function within the control unit. Instead of having separate systems for eye tracking and control generation, the control unit integrates both capabilities, processing eye movement signals and translating them into navigation commands in a unified manner. This consolidation simplifies the system architecture while enabling gaze-based interaction.
