The development of programming skills is a motivating issue in computer science. Programming languages have been increasingly used to map end-users needs and mental models. The nu...
When facing dynamic optimization problems the goal is no longer to find the extrema, but to track their progression through the space as closely as possible. Over these kind of ov...

This paper discusses possibilities and problems arising in the design of usable interactive systems when both visual and haptic interaction modes are available. Communicational an...
We present an algorithm Pref-AC that limits arc consistency (AC) to the preferred choices of a tree search procedure and that makes constraint solving more efficient without chan...
Interaction cost is an important but poorly understood factor in visualization design. We propose a framework of interaction costs inspired by Norman's Seven Stages of Action ...
