Summary
Gesture recognition for cooperative driving allows drivers to keep eyes on the road, unlike tactile displays. However, tactile displays avoid input errors, while gesture recognition struggles with accuracy, requiring further research for optimal human-machine interfaces.
Area of Science:
- Human-computer interaction
- Automotive engineering
- Driving simulation
Background:
- Cooperative maneuver-based driving is crucial for future transportation systems.
- Evaluating intuitive and safe human-machine interfaces (HMIs) is essential for driver assistance systems.
- The
- Conduct-by-Wire
- project investigates advanced driving concepts.
Purpose of the Study:
- To compare the performance and usability of two distinct input devices for cooperative driving: gesture recognition and tactile touch displays.
- To assess the impact of input device choice on driver attention and input accuracy.
- To determine the most suitable HMI for future cooperative driving scenarios.
Main Methods:
- A simulator study was conducted with 29 participants.
- Participants interacted with vehicle control functions using both gesture recognition and tactile touch display interfaces.
- Key metrics included gaze behavior (time spent looking away from the road) and input error rates.
Main Results:
- Gesture recognition significantly reduced the need for drivers to divert their gaze from the road.
- Tactile touch displays resulted in a significantly higher number of gazes away from the road.
- Gesture recognition systems exhibited significantly more input errors compared to tactile touch displays, which had no input errors.
Conclusions:
- Gesture recognition offers a potential advantage in maintaining driver situational awareness by keeping eyes on the road.
- Tactile touch displays provide superior input accuracy, crucial for safety-critical driving functions.
- Further research and development are necessary to optimize gesture recognition accuracy and determine the optimal HMI for cooperative driving.
