Virtual Video Camera Roto-Translation Control for Flight Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems for three-dimensional virtual spaces, particularly in flight simulation, require complex manual commands for the virtual video camera to track aircraft movements intuitively and efficiently, lacking simplicity and speed in navigation and rotation.
Innovation Solution
An electronic system with a processing unit that implements a roto-translation algorithm, allowing the virtual video camera to automatically adjust its pointing axis based on user input within an imaginary displacement plane, enabling easy tracking of aircraft parts by translating and rotating the camera with a single operation of the pointer.

Engineering Contradiction Analysis
1Ease of operation
If manual control commands are used for virtual video camera navigation, then the operator can control camera translation and rotation, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent merges translation and rotation controls into a single unified interface element (the movable icon on the touchscreen). By combining multiple camera control functions into one integrated control mechanism, the operator can perform both translation and rotation operations without switching between separate controls, thereby simplifying operation and reducing time loss.
Solution Approach 2:
The patent introduces a two-dimensional touchscreen interface that represents three-dimensional camera movements. The movable icon on the touchscreen plane maps to camera position and orientation in 3D space, allowing operators to control complex 3D navigation through simple 2D gestures, thus reducing operational complexity and time.
2Ease of operation
If multiple separate controls are provided for camera translation and rotation, then precise control is possible, but the device complexity increases
Solution Approach 1:
The movable icon on the touchscreen serves multiple functions simultaneously - it controls both camera translation and rotation, and can be positioned to achieve different viewing angles and distances. This multi-functional control element reduces the number of separate controls needed while maintaining comprehensive camera navigation capability.
Solution Approach 2:
The touchscreen interface acts as an intermediary between the operator and the complex 3D camera control system. The movable icon translates simple touch gestures into complex camera translation and rotation commands, shielding the operator from the underlying system complexity while maintaining ease of use.
