Iacolina, Samuel A., Soro, Alessandro and Scateni, Riccardo (2011): Improving FTIR based multi-touch sensors with IR shadow tracking. In: ACM SIGCHI 2011 Symposium on Engineering Interactive Computing Systems 2011. pp. 241-246.

Frustrated Total Internal Reflection (FTIR) is a key technology for the design of multi-touch systems. With respect to other solutions, such as Diffused Illumination (DI) and Diffused Surface Illumination (DSI), FTIR based sensors suffer less from ambient IR noise, and is, thus, more robust to variable lighting conditions. However, FTIR does not provide (or is weak on) some desirable features, such as finger proximity and tracking quick gestures. This paper presents an improvement for FTIR based multi-touch sensing that partly addresses the above issues exploiting the shadows projected on the surface by the hands to improve the quality of the tracking system. The proposed solution exploits natural uncontrolled light to improve the tracking algorithm: it takes advantage of the natural IR noise to aid tracking, thus turning one of the main issues of MT sensors into a useful quality, making it possible to implement pre-contact feedback and enhance tracking precision.

Soro, Alessandro, Iacolina, Samuel Aldo, Scateni, Riccardo and Uras, Selene (2011): Evaluation of user gestures in multi-touch interaction: a case study in pair-programming. In: Proceedings of the 2011 International Conference on Multimodal Interfaces 2011. pp. 161-168.

Natural User Interfaces are often described as familiar, evocative and intuitive, predictable, based on common skills. Though unquestionable in principle, such definitions don't provide the designer with effective means to design a natural interface or evaluate a design choice vs another. Two main issues in particular are open: (i) how do we evaluate a natural interface, is there a way to measure 'naturalness'; (ii) do natural user interfaces provide a concrete advantage in terms of efficiency, with respect to more traditional interface paradigms? In this paper we discuss and compare observations of user behavior in the task of pair programming, performed at a traditional desktop versus a multi-touch table. We show how the adoption of a multi-touch user interface fosters a significant, observable and measurable, increase of nonverbal communication in general and of gestures in particular, that in turn appears related to the overall performance of the users in the task of algorithm understanding and debugging.

Lai, Alessandro, Soro, Alessandro and Scateni, Riccardo (2010): Interactive calibration of a multi-projector system in a video-wall multi-touch environment. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 437-438.

Wall-sized interactive displays gain more and more attention as a valuable tool for multiuser applications, but typically require the adoption of projectors tiles. Projectors tend to display deformed images, due to lens distortion and/or imperfection, and because they are almost never perfectly aligned to the projection surface. Multi-projector video-walls are typically bounded to the video architecture and to the specific application to be displayed. This makes it harder to develop interactive applications, in which a fine grained control of the coordinate transformations (to and from user space and model space) is required. This paper presents a solution to such issues: implementing the blending functionalities at an application level allows seamless development of multi-display interactive applications with multi-touch capabilities. The description of the multi-touch interaction, guaranteed by an array of cameras on the baseline of the wall, is beyond the scope of this work which focuses on calibration.

Soro, Alessandro, Marcialis, Ivan, Carboni, Davide and Paddeu, Gavino (2005): WebRogue: virtual presence in web sites. In: Proceedings of the 2005 International Conference on the World Wide Web 2005. pp. 932-933.

WebRogue is an application for virtual presence over the Web. It provides the Web Browser with a chat subwindow that allows users connected to the same Web site to meet, share opinions and cooperate in a totally free, non moderated and uncensored environment. Each time the user loads a Web page in the Web Browser, WebRogue opens a discussion channel in a centralized server application, that is completely decoupled from the Web server, using the URL of the Web site as a key. Thus whenever a new page is loaded the user can see who is connected, as if entering a physical site. Interactivity is supported by means of two type of commands: comunication commands allow synchronous interaction as with chat or instant messaging software; Social commands allow cooperation: group surfing, exchange of visit-cards and wait in line.
