The application of didactic setups is one of the commonly used teaching methods at schools and universities nowadays. By using the didactic setups, students are introduced to real components and real processes that take place in the industry. However, the students often need to use the didactic setups outside of regular teaching activities and at times when teaching staff is unavailable. This paper presents a solution for improving the safety of using the didactic setups by applying an augmented reality solution. The presented solution was implemented on a didactic setup for control of a three-phase asynchronous motor. In addition to improving the safety, the proposed solution allows the students to autonomously use the didactic setups beyond regular teaching hours.
