Mechanix是一个草图识别工具，为工程专业学生学习如何绘制桁架自由体图（fbd）和解决桁架问题提供了有效的手段。该系统允许学生在平板电脑上或用鼠标绘制这些fbd草图，就像他们用手一样，鼠标也可以用来在普通电脑和显示器上绘制草图。然后，Mechanix能够向学生提供即时反馈，并告诉他们是否缺少FBD的任何组件，而不提供答案。该程序还能够告诉他们解出的反作用力或成员力是否正确。本文提出了一项研究，以评估在课堂上使用Mechanix作为传统教学方法的补充的有效性和优势。目前的结果表明，学生们相信Mechanix可以提高他们的学习效果，并且在使用它时高度投入。本文还讨论了进一步改进该程序的工作。
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 students to sketch these FBDs into a tablet computer or by using a mouse just as they would by hand, a mouse can also be used to draw the sketch using a regular computer and monitor. Mechanix is then able to provide immediate feedback to the students and tell 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 a study 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.
