Interactive systems

Since the PST is located in the ISTC, where a number of well-known researchers in environmental psycology and similar disciplines enrich us with their points of view, we have developed particular sensitivity to the problem of designing intelligent systems able to interact with humans. This particular aspect of human computer interaction (HCI) has taken different shapes during the years and has stimulated us to establish solid collaborations with our collegues in a number of research projects.

In all instances, our work has dealt with the use of planning technology in two kinds of tasks: (a) to generate different tasks for humans (interactive intelligent solvers); (b) to solve problem integrating human-machine abilities (mixed-initiative problem solving). Up to now we have mostly paid attention to type-a scenarios:

More recently, we have given increasing attention to type-b problems:

In research more connected to complex problem solving we are studying how to make the user adequaltely involved in the solution process:

At present we are investigating several aspects connected to mixed initiative problem solving like the development of measure to compare different systems, to the synthesis of explanation for the user to have him/her involved in the constraint-based activity. A different aspect is connected to acceptability of interlligent systems and is currently connected to our studies in domotics.

In pursuing this aim several remarkable aspects have been considered: "user-centered" design principles, interactive problem solving paradigms, evaluation metrics, usability and acceptability studies. One of the scopes of the PST's work includes designing and testing innovative tools and technologies to support human activities and problem solving tasks by promoting an interactive and fruitful collaboration between human and artificial solvers. The PST carries on this tradition by fostering multidisciplinary research whose principal lines are in the field of human-computer interaction, user-interface software tools, cognitive models, intelligent agents, collaborative and mixed-initiative problem solving.
