Learning Effect in Joystick Tactile Guidance

Area of Science:

• Human-Computer Interaction
• Aerospace Engineering
• Cognitive Psychology

Background:

• Haptic feedback offers tactile guidance for tasks demanding multiple senses and attention, such as aviation.
• Previous simulator and flight tests highlighted the need to investigate the learning curve associated with haptic guidance.

Purpose of the Study:

• To analyze the learning effect of haptic guidance in aviation-related tasks.
• To quantify improvements in performance metrics and self-assessed workload over multiple training sessions.

Main Methods:

• Twelve participants undertook two haptic guidance tasks without visual input across twelve sessions.
• Performance was evaluated based on guidance accuracy, response time, and reaction delay.

Main Results:

• Significant improvements were observed in guidance accuracy and response time between training sessions.
• Self-assessed workload also decreased with training.
• Reaction delay did not show significant changes due to training.

Conclusions:

• Haptic guidance is a learnable skill that enhances performance in complex tasks.
• Training leads to substantial improvements in accuracy and efficiency, with a notable 30% increase in guidance accuracy.
• Further research may explore optimizing training protocols for reaction time components.
