Mechanix: A Sketch-Based Tutoring System that Automatically Corrects Hand-Sketched Statics Homework Chapter uri icon


  • With the rise in classroom populationsin both physical classrooms and online learning environments such as massively open online coursesinstructors are struggling to provide relevant and personalized feedback on student work. As a result, many instructors choose to structure their homework assignments and assessments via multiple-choice questions or other more automatable techniques, rather than assign complete problems and diagrams. In this work, we aim to provide a new solution to the instructors of introductory engineering courses. We leveraged the power of sketch-recognition and artificial intelligence to create Mechanix, a sketch-based system that tutors students through drawing and solving free-body diagrams. Mechanix can support problems that have only a single answer, as well as questions for which many answers might apply (i.e. design this vs. solve this).
