Pilot Physiological Feedback

Olaitan Adeleke, Lucy E. Dunne

Introduction

Textile covers major part of the body and provides opportunity to acquire bio-signals and provide haptic feedback with minimal intrusion. In this study we explored how we can acquire and analyze vital bio-signals to provide real time haptic feedback to the pilots in tense moments during flight.

Objectives

To explore the feasibility and potential challenges of designing a wearable system that analyzes physiological bio-signals to provide real time feedback to pilots.
To know the best sensor type and sensor placement position to get optimal feedback.

Theoretical Framework

Method

Conclusion and Implications

Breathing rate is a primary bio-signal to be measured in monitoring pilot’s physiological state during flight.
Integrating sensors and actuators can be very difficult because of the different materials textiles (soft) and actuators (hard) are made of.
Motion artifacts and noise filtering tends to be a major factor in the sensing unit.
Optimal input signals were collected in a sitting position. This is an advantage in this case study because the pilot would mostly be in a sitting position during flight.
Chest breathing movement gave a smaller amplitude range values than the abdominal breathing. Higher breathing movement was observed at the ribcage region.
