  Augmented Reality (AR) solutions are providing tools that could improve
applications in the medical and industrial fields. Augmentation can provide
additional information in training, visualization, and work scenarios, to
increase efficiency, reliability, and safety, while improving communication
with other devices and systems on the network. Unfortunately, tasks in these
fields often require both hands to execute, reducing the variety of input
methods suitable to control AR applications. People with certain physical
disabilities, where they are not able to use their hands, are also negatively
impacted when using these devices. The goal of this work is to provide novel
hand-free interfacing methods, using AR technology, in association with AI
support approaches to produce an improved Human-Computer interaction solution.
