O'Neil and Associates sent in a challenge problem to design an Augmented Reality (AR) Maintenance Trainer.

They wanted additional research done on how to create AR trainers using various techniques or software.

The AR Maintenance Trainer needed to assist users as they perform a maintenance routine on a physical object by providing various forms of guidance.

Students designed the AR trainer using Unreal Engine 4, AR Core, and Android mobile devices.

Autodesk Fusion 360 and Blender were also utilized for designing and updating maintenance object models.

The project concluded with the construction of a fully functional AR Maintenance Trainer and student-provided feedback that the customer was happy with.

In the trainer, a user first selects the maintenance routine to perform and then scans a physical target image to place the virtual object.

Then the user steps through their chosen routine which provides animations and step-by-step instructions on how to perform their tasks.

Implementing voice recognition and text to speech into the project would be beneficial for a maintenance worker as they would not need to continuously refer back to the device.

Adding in data logging would help supervisors as they could see areas in which their maintainers excel in or need further assistance.
