A prototype of a handheld augmented reality application to get familiar with ultrasound equipment knobology

Abstract

Aims: A prototype application has been developed that is adapting modern augmented reality technology to support learning in ultrasound skills-labs or at home. The application enables students to get in real-time an orientation and information about the knobs on an equipment´s control panel that is available in the lab.

Material and methods: The Augmented reality (AR) application for smartphones or tablets was created in Unity (San Francisco) with the software development kit Vuforia (Vuforia PTC Inc., Zurich) to support students with their own devices to learn the knobology of an ultrasound equipment. An interface was modelled, which is superimposed on the live camera image and provides information about the displayed knobs and sliders on the control panel.

Results: The smartphone or tablet app is able to detect the specific ultrasound equipment in real in the skills-lab, as well as from a hardcopy photo or displayed by a monitor and to provide further detailed information. The application can be used therefore as preparation of a practical course or for orientation within the lab at the equipment.

Conclusions: The flexibility of the app is optimal for students to become familiar with the equipment before they are having their skills-lab lecture and might help to reduce time for introduction to orientation at the equipment´s console.
