Wearable Training Platform for Aviation Mechanics
My capstone team was tasked by the DRDC with developing a wearable training system for aviation mechanics. The goal of this project was to identify the most appropriate devices that would need to be incorporated into this system as well as to determine if such a system would be an effective and viable replacement for traditional learning platforms. My role within the team was to identify the most suitable biofeedback device and integrate it into the system.

The first stage of this project was to explore existing technologies and define "The Art of the Possible". Studies have shown having knowledge about and the ability to control one's involuntary physiological functions (such as breathing rate) while performing a task can lead to improved performance. Towards this end, the Microsoft Band 2 was chosen because of its variety of sensors that allowed us to determine markers such as heart rate and heart rate variability.
Due to incompatibility issues between the Microsoft Band 2 and the Epson Moverio smart glasses (seen on the home page) a relay device - Samsung Galaxy S4 - was used. Using the sample code from the Band SDK and bluetooth connectivity instructions from the Android API Guide, communication was established between the Band, through the phone and to the Moverio.
For this project, the transmission of heart rate (HR) data to the user was deemed to be a suitable piece biofeedback information as a proof of concept. The HR is displayed in blue and once a critical threshold, with respect to a baseline HR, is reached it turns orange. The black background on the smart glasses simulate the user's field of view. Future steps would include introducing mitigation methods once the critical threshold is reached.
In order to demonstrate the usability and effectiveness of our system, the human factors lead and I designed an experiment based on HCI principles. The experiment was designed to test the user's comprehension, completion rate and accuracy while assembling a simple organizer. This experiment can be extended for its desired use case by utilizing the aviation course material, accessible through the system.
