Interactive sketching in multi-touch digital books. A prototype for technical graphics

In this paper, we present a functional prototype of an interactive multi-touch book with drawing capabilities, intended to enhance the understanding of engineering graphics concepts and improve visualization skills. Our multi-touch book combines textual elements with rich media content and interactive exercises to allow students to practice technical sketching in an environment that simulates traditional paper-based drawings and tools. Additionally, finished drawings can be submitted to the instructor via email directly from the digital book, which facilitates management tasks. A comparative study of traditional and digital sketching using our prototype was conducted with a small group of participants to evaluate the effectiveness of the tool. Preliminary results show positive reactions and acceptance.
