3D Touch UAV Target Selection With Orientation-Matched Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAV control systems lack intuitive and reliable methods for remote controlling unmanned aerial vehicles (UAVs) to interact with complex physical environments, leading to challenges in selecting targets or waypoints and navigating without collisions.
Innovation Solution
A computer-implemented UAV control method that utilizes a touch-sensitive display to overlay a moveable target indicating symbol in a 3D-view of the UAV's environment, dynamically changing its appearance to match the orientation of the underlying face, providing real-time feedback for target selection and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional 2D control interface is used for UAV navigation, 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 3D representation of the physical environment on a 2D touch-sensitive display. The 3D-view allows users to interact with spatial data as if it were three-dimensional, enabling intuitive target selection by directly touching locations on the displayed 3D environment rather than using complex coordinate inputs or manual navigation controls.
Solution Approach 2:
The patent creates a visual copy of the physical environment in 3D format that can be manipulated through touch inputs. This copied representation includes spatial relationships and terrain features that mirror the real world, allowing users to select targets by touching the displayed 3D scene rather than interpreting abstract control commands.
2Reliability
If repeated touch inputs are required for accurate target selection, then the reliability of target selection improves, but the loss of time increases due to multiple adjustment attempts
Solution Approach 1:
The patent implements feedback by displaying a target indicator symbol that moves in real-time as the user drags their finger across the touch-sensitive display. The system continuously updates the position of the target indicator based on the user's touch movements, providing immediate visual feedback about which target will be selected. This eliminates the need for repeated attempts by showing the exact selection outcome during the input process.
Solution Approach 2:
The patent performs preliminary action by calculating and displaying the target selection result in advance, during the drag operation itself. Rather than waiting for the user to complete the input and then showing the result, the system continuously determines and displays the intended target position based on the current touch location, allowing users to see the outcome before finalizing the selection.
3Ease of operation
If a 3D-view is displayed on a 2D display plane, then the ease of operation improves through intuitive spatial representation, but the loss of information occurs due to potential distortion of depth perception
Solution Approach 1:
The patent uses dimensionality change techniques to represent 3D spatial data on a 2D display while preserving depth information through perspective projection. The 3D-view rendering engine transforms three-dimensional coordinates into two-dimensional screen coordinates while maintaining spatial relationships, allowing users to perceive depth and distance intuitively despite the flat display medium.
