Mechanix: A Sketch Recognition Truss Tutoring System

Abstract

Mechanix is a sketch recogniton tool that provides an efficient means for engineering students to learn how to draw truss free-body diagrams (FBDs) and solve truss problems. The system allows students to sketch these FBDs into a tablet computer or by using a mouse just as they would by hand. Mechanix is then able to provide immediate feedback to the students and tells them if they are missing any components of the FBD, without providing answers. The program is also able to tell them whether their solved reaction or member forces are correct or not. This paper presents studies to evaluate the effectiveness and advantages of using Mechanix in the classroom, as a supplement to traditional teaching and learning methods. Current results demonstrate that students believe Mechanix enhances their learning and are highly engaged when using it. Future work on the refinement of the program is also discussed.
