Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in control rooms face physical and mental strain due to prolonged use of 2D computer screens, limited workspace, and the need for multiple screens, which is costly and inefficient, while also seeking a method to improve accessibility and ergonomics for technical information and control applications.
Innovation Solution
A system using augmented reality to create a 3D virtual desktop on wearable devices like Head-Mounted Displays, allowing users to interact with virtual functional interfaces in 3D space using hand gestures or input devices, eliminating the need for physical screens and enhancing mobility and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple 2D desktop screens are used to display functional interfaces, then accessibility to technical information is improved, but workspace area and cost increase
Solution Approach 1:
The patent transitions from 2D desktop screens to a 3D virtual environment where functional interfaces are distributed in three-dimensional space around the user. This dimensional change allows interfaces to be positioned at various depths and angles, effectively increasing the accessible workspace without requiring additional physical screen area.
Solution Approach 2:
The system creates virtual copies of functional interfaces in a 3D space rather than using multiple physical screens. These virtual interfaces can be positioned throughout the user's field of view, providing extensive information access without the physical footprint of multiple monitors.
2Loss of information
If multiple desktop screens are provided for each user, then information accessibility is improved, but cost and device complexity increase
Solution Approach 1:
The system uses a single physical display device that can present multiple functional interfaces simultaneously in different spatial locations. This multi-functional approach allows one screen to replace what would traditionally require multiple screens, reducing both cost and complexity while maintaining full information accessibility.
Solution Approach 2:
By adding the third dimension to interface presentation, the system can display multiple functional interfaces in a single physical screen's field of view. Interfaces are positioned at various depths and angles, allowing comprehensive information access without requiring multiple physical displays.
3Stability of the object's composition
If operators work in fixed positions for prolonged periods, then operational stability is maintained, but physical strain and ergonomics deteriorate
Solution Approach 1:
The system allows operators to dynamically move and reposition functional interfaces in 3D space during operation. Interfaces can be adjusted to optimal positions based on the operator's current needs and physical state, enabling movement and posture changes while maintaining stable operational control.
Solution Approach 2:
The system enables operators to change spatial parameters of functional interfaces (position, depth, angle) to optimize ergonomics. By adjusting these parameters, operators can maintain operational stability while reducing physical strain through varied working positions and movements.
