SciSketch

Abstract

Sketching is a vital process in scientific research and procedural learning. In educational contexts, sketching helps students visualize abstract concepts and facilitates communication with their instructors as well as with other students. Inspired by a problem-based learning science class in which students use papers and pens to collaboratively sketch diagrams and equations for given problems, we aim to provide a digital tabletop platform for collaborative learning and customization. Current tabletop systems are unaffordable to be widely adopted in the classroom and are unable to identify multiple pens. We propose a pen-based tabletop system that utilizes a low-cost high-frame-rate infrared camera and HTML5 web canvas programming, making it cheaper and easier to customize for specific uses.

Study on generic tangible objects used to collaborate remotely on RFID tabletops

“…Source du renvoi introuvable. 3 shows the instantiation of the generic objects (with a picture of each item): they correspond to concrete software implementations of the tangigets identified above (see Table 2), covering the different collaboration styles.…”

“…• The possibility of working with tolerable levels of precision (unlike a limited size screen that requires high precision pointing). Such advantages have encouraged researchers to design and develop applications with collaborative elements to be performed around the same surface (see [2][3][4][5][6][7]). Other studies have tried to go further by exploiting the concept of remote collaboration via at least two interactive surfaces.…”
