Abstract
Interactive Whiteboards (IWs) have been massively in- troduced in schools. While the benefits of these devices in the learning process are well known, dedicated software lack of functionality. In particular, most of the existing tools for IWs are an adaptation of classical software used on Per- sonal Computers, mainly based on buttons and menus. The objective of the research presented in this paper is to com- pletely re-think the interaction paradigm of the software for the IW, in such a way that the input is only composed of pen draws and hand-touches. In order to test this idea in practice, we apply it to the case of the teaching of geom- etry. Hence, more specifically, in this paper we propose a smart sketch-based tutoring system for IW that combines the recognition of hand-drawn geometrical shapes to the use of multi-touch gestures to support the editing of the drawn shapes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
