Abstract
Freehand sketch is a fast and easy tool for idea development and communication, especially in the critical front-end or predevelopment stages. While it is important to any designer, lacking of appropriate mechanism for correction in fundamental design education makes even professionals hard to precisely handle accuracy of perspective sketch. Based on two-point perspe-ctive method and using cubic shape as subject, this research develops reverse drawing approach and accordingly establishes a digital training system for freehand sketch practice, namely Perspective Practice. Users can operate con-ventional pen and paper for input and the system automatically illustrates on screen a correct perspective drawing on top of the sketch done by the user, pointing out the concept or technique for improvement. The system provides users with ways in understanding their current skills and guidelines for impro-vement, through which the efficacy in digital technical training can be enhanced.
