Solution Overview
Problem
Existing driving simulators do not effectively address motion sickness and physical disabilities, limiting user interaction and accessibility.
Innovation Solution
The system includes a virtual reality headset that receives sensor data to detect motion sickness and adjusts feedback devices accordingly, and a controller that adapts input devices based on user disabilities, allowing for customized driving scenarios and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driving simulators use standard input devices and feedback mechanisms, then the system structure remains simple, but users with physical disabilities cannot effectively interact with the simulator
Solution Approach 1:
The system dynamically adapts input devices and feedback mechanisms based on detected user disabilities. The controller receives disability type data and automatically configures appropriate input devices (e.g., activating eye tracking for mobility impairments, adjusting feedback delivery for sensory impairments), transforming a static system into one that flexibly reconfigures itself to accommodate different user needs.
Solution Approach 2:
The system changes operational parameters such as input device activation states, feedback intensity levels, and scenario difficulty based on user disability characteristics. By adjusting these parameters dynamically, the simulator maintains accessibility across diverse user populations without requiring completely different hardware configurations for each disability type.
2Productivity
If driving simulators provide intense visual and motion feedback, then the training effectiveness increases, but users experience motion sickness
Solution Approach 1:
The system implements a closed-loop feedback mechanism where sensor data from the user (e.g., heart rate, eye tracking, motion sensors) is continuously monitored to detect early signs of motion sickness. Based on this feedback, the controller dynamically adjusts visual feedback intensity, motion platform activation, and scenario parameters to maintain training effectiveness while preventing motion sickness onset.
Solution Approach 2:
The system takes preliminary anti-action by detecting predisposition to motion sickness through sensor data analysis and proactively adjusting feedback intensity before motion sickness fully develops. This preventive approach allows the system to maintain optimal training conditions while avoiding the harmful effects of excessive sensory stimulation.
