CAI platform for fundamental geometric training on perspective sketching

Abstract

For most designers, freehand sketching is the primary tool for conceptualization in the early stage of the design process. However, existing education programs on concept presentation techniques rarely emphasizes the practicing of two most fundamental geometric shapes - cube and cylinder. Lack of correct reference and proper training, students often end up with disproportioned sketches that deviate from common visual experience which would lead to misunderstanding of original design.This research developed a computer-assisted cube sketching instruction platform for novice, with which users can practice correct cube sketching using freehand skills or digital devices for self-improvement. This platform can provide instant corrective feedback and demonstrated 19% sketch accuracy increased relative to the control group in a series of experiments. Based on the successful experience, a cylinder training program is under development. The ultimate goal of which is to develop a comprehensive CAI platform to help novice improve their skills by self learning and correction. © 2011 Springer-Verlag.
