Mechanix: A Sketch-Based Tutoring and Grading System for Free-Body Diagrams
2012
The AI Magazine
Preserved Fulltext
In this paper, we introduce Mechanix, a sketch-based deployed tutoring system for engineering students enrolled in statics courses. ...
Our system not only allows students to enter planar truss and free body diagrams into the system just as they would with pencil and paper, but our system checks the student's work against a hand-drawn ...
Acknowledgements The authors thank the many other contributors to Mechanix, specifically Martin Field and Chris Aikens. ...

Abstract Mechanix is a sketch recognition 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 for students to sketch these FBDs, as they normally would by hand, into a tablet computer; a mouse can also be used for regular computer monitors. ...
