Design and testing of an Augmented Reality solution to enhance operator safety in the food industry

Augmented reality (AR) systems help users perform tasks and operations in man–machine interaction, by adding virtual information (such as live-video streams, pictures or instructions) to the real-world environment. This paper describes the design and testing of an AR solution created to enhance the safety of employees when carrying out maintenance tasks on a food processing machine. The machine which was analyzed is a hot-break juice extractor used to obtain juice from fruits and vegetables by separating out seeds and peel. The maintenance task for which the AR system is intended involves cleaning the machine’s porous sieves or substituting them with clean replacements and should be carried out at least every 12 hours while the plant is in operation. The paper discusses the main steps involved in developing the AR solution, its testing in the real operating environment and the expected pros/cons of its implementation and use.
