With the aim of presenting a motivating experience that promotes learning in the field of three-dimensional statics, and developing improved problem-solving strategies for engineering students, a tool using augmented reality was designed to be applied in the context of physics. This paper proposes the design of a mobile application and its preliminary implementation to carry out usability testing of this augmented reality tool designed for its use in engineering education which is part of the STEM field. In the initial phase, 2D models were designed to represent scenarios following the features of the problem-based learning approach. Then, these scenarios were transformed into three-dimensional models. The second phase of the project refers to the implementation of the tool through usability tests, and finally, the third phase of the document or the analysis phase, focuses on the analysis of the usability results to make necessary adjustments in order to offer better user experience.
