3D Touch UAV Waypoint Selection With Surface-Matched Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote controlling of UAVs in complex environments is challenging due to the need for intuitive and reliable selection of targets or waypoints, often requiring multiple user inputs and lacking feedback during the selection process, which can lead to inefficiency and increased collision risk.
Innovation Solution
A computer-implemented UAV control method that displays a 3D-view of the environment on a touch-sensitive screen, allowing users to intuitively and reliably select targets or waypoints by overlaying a movable target indicating symbol, which dynamically changes appearance based on the underlying object's orientation and texture, providing continuous feedback during the selection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional 2D interface is used for UAV control, then the device complexity is reduced, but the ease of operation deteriorates due to difficulty in intuitively selecting targets in 3D environment
Solution Approach 1:
The patent applies dimensionality change by displaying a three-dimensional view of the environment on a two-dimensional touch-sensitive display. This allows users to interact with 3D spatial representations (buildings, obstacles, targets) using 2D touch gestures, making target selection more intuitive while maintaining compatibility with standard display devices. The 3D view preserves depth information and spatial relationships without requiring complex 3D hardware interfaces.
2Reliability
If multiple user inputs are required for target selection, then the reliability of target selection improves, but the productivity deteriorates due to increased time and steps required
Solution Approach 1:
The patent implements feedback by displaying a movable target indicating symbol that provides continuous visual feedback during the selection process. As users drag the symbol across the 3D view, they can see its position relative to buildings, obstacles, and potential targets in real-time. This immediate feedback allows users to confirm correct target selection during the dragging motion itself, eliminating the need for multiple confirmation steps while maintaining high accuracy.
Solution Approach 2:
The target indicating symbol is pre-configured with properties such as color, transparency, and size that are optimized for visibility and interaction. The symbol is also pre-programmed to respond to touch gestures and update its position continuously during dragging, enabling users to perform selection in a single continuous action rather than through multiple discrete steps.
3Ease of operation
If a static target indicating symbol is used, then the device complexity is reduced, but the ease of operation deteriorates due to lack of feedback during selection
Solution Approach 1:
The patent applies dynamics by making the target indicating symbol movable rather than static. The symbol can be dragged across the 3D view by user touch input, and its position updates continuously during the dragging motion. This dynamic behavior provides intuitive feedback as users can see the symbol's position relative to environmental features in real-time, making the selection process more interactive and user-friendly without requiring complex additional components.
Solution Approach 2:
The target indicating symbol utilizes color and transparency properties to provide visual feedback. The symbol can be configured with specific colors and transparency levels that make it visible against various backgrounds in the 3D view. These visual properties help users track the symbol's position and understand its relationship to surrounding objects during the selection process.
