3D Touch Guidance Interface for Agricultural Vehicle Autosteering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic guidance systems for agricultural vehicles require close operator monitoring due to potential misinterpretation of image data, leading to increased operator workload and the need for manual intervention.
Innovation Solution
An operating system that utilizes a three-dimensional imaging device and a touch-sensitive display unit to capture and interact with real objects, generating three-dimensional data set-based command signals for controlling the vehicle, allowing for direct manipulation of displayed objects to control the agricultural vehicle's steering, throttle, and brakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic steering devices are used to relieve the operator, then the operator's workload is reduced, but the operator needs to monitor the device closely and may need to take over manually due to misinterpretation of image data, thus increasing workload
Solution Approach 1:
The patent changes the data representation parameter from two-dimensional image data to three-dimensional data sets, which provide more accurate spatial information about the environment. This parameter change enables more reliable automatic guidance while reducing the need for operator monitoring, as the 3D data structure inherently provides better depth and distance information for navigation decisions.
2Device complexity
If traditional two-dimensional image data is used for guidance, then the system is simpler, but the operator needs to monitor closely due to potential misinterpretation
Solution Approach 1:
The patent adds a third dimension to the data representation by using three-dimensional data sets instead of traditional two-dimensional images. This dimensional enhancement provides explicit depth and distance information, reducing ambiguity in environmental perception and decreasing the operator's need for close monitoring, while the touch-sensitive interface maintains ease of use.
3Adaptability or versatility
If the operator manually controls the vehicle, then the operator has full control, but the operator needs to control several tasks simultaneously, increasing workload
Solution Approach 1:
The patent implements a multi-functional operating system that can operate in multiple modes: fully automatic guidance using three-dimensional data, semi-automatic mode where the operator can intervene, and manual control. The touch-sensitive display provides a universal interface for all operating modes, allowing the operator to switch between tasks and control levels as needed, reducing workload while maintaining flexibility.
