Learning Effect in Joystick Tactile Guidance.

Haptic feedback is a method to provide tactile guidance in scenarios requiring multiple senses and divided attention like aviation. Earlier tests on a flight simulator and an in-flight test using the proposed tactile guidance method have shown the need to study its learning process. In this study, twelve participants completed two tactile guidance tasks without visual feedback across twelve sessions to analyze the learning effect. The paper shows an improvement between sessions in guidance accuracy, response time, and self-assessed workload. On the other hand, reaction delay is not affected by the training. The percentage improvement between the initial and trained skills reached 30 % in guidance accuracy performance.
