abstract

  • Design Sketching is an important tool for designers and creative professionals to express their ideas and thoughts onto visual medium. Being a very critical and versatile skill for engineering students, this course is often taught in universities on pen and paper. However, this traditional pedagogy is limited by the availability of human instructors for their feedback. Also, students having low self-efficacy do not learn efficiently in traditional learning environment. Using intelligent interfaces this problem can be solved where we try to mimic the feedback given by an instructor and assess the student drawn sketches to give them insight of the areas they need to improve on. PerSketchTivity is an intelligent tutoring system which allows students to practice their drawing fundamentals and gives them real-time assessment and feedback. This research deals with finding the evaluation metrics that will enable us to grade students from their sketch data. There are seven metrics that we will work with to analyse how each of them contribute in deciding the quality of the sketches. The main contribution of this research is to identify the features of the sketch that can distinguish a good quality sketch from a poor one and design a grading metric for the sketches that can give a final score between 0 and 1 to the user sketches. Using these obtained features and our grading metric method, we grade all the sketches of students and experts.
