设计素描是一个强大的工具，可以有效地从纸笔表达想法，并成为一个更全面的沟通者。素描教师通常在他们的教室里使用笔和纸来向学生传达这些基本原理。然而，这种传统的方法限制了教师的带宽和能力，以提供及时和个性化的反馈。智能辅导系统可以利用领域专家设计草图教师的知识，使学生可以在课堂时间之外进行练习并获得实时反馈。我们的系统利用了咨询教师的见解和观察到的教学实践的一个活跃的大学设计素描课程，并将它们应用于一个掌握为基础的练习，利用草图识别，以提供实时反馈的进展。我们的系统的可用性在一类工程专业的学生学习设计草图的评估表明，它表现得很好，被学生看作是一个激励和直观的实践工具，并允许学生提高他们的草图的准确性和速度。
Design sketching is a powerful tool for expressing ideas from pen and paper effectively and becoming a more well-rounded communicator. Sketching instructors conventionally employ pen and paper in their classrooms to convey these fundamentals to students. However this traditional approach limits the bandwidth and capability of instructors to give timely and individualized feedback. An intelligent tutoring system can leverage the knowledge of domain expert design sketching instructors so that students can practice and receive real-time feedback outside of classroom hours. Our system leverages consulted instructor insights and observed pedagogical practices of an active university design sketching curriculum, and applies them in a mastery-based progression of exercises that utilize sketch recognition to give real-time feedback. An evaluation of our system's usability in a class of engineering students studying design sketching showed that it performed very well, was seen by the students as a motivating and intuitive practice tool, and allowed the students to improve the accuracy and speed of their sketches.
