Developing an augmented reality based training demonstrator for manufacturing cherry pickers

This paper presents an Augmented Reality (AR) demonstrator to test its feasibility with enhancing the training process, improving learning time and error rate. The application environment was a manufacturer of cherry pickers. The demonstrator focused on covering the assembly of hydraulic hoses to the relative valve; the choice was driven by Company needs. Requirements led to the choice of Microsoft HoloLens as hardware, while Unity and Vuforia were used as software. The demonstrator provides sequential instructions through texts, images and animations. Results showed improvements when introducing AR for error rates and for the average assembly times.
