We present Touch&Screen, a wide set of interaction techniques for the remote control of widgets (menu, lists, videos, maps etc.) for large screens through smartphones. After presenting the design of these widgets and the related control interfaces of the smartphone, we evaluated the interaction through two user studies. The first study (48 users) aimed to evaluate the user experience (naturalness, usability, etc.) and spontaneity of use. The second user study (12 users) aimed to evaluate our interaction techniques comparatively with direct touch and a commercial smartphone application designed to control cursors on distant screens. The evaluation results show that Touch&Screen is faster and more natural than existing solutions to control distant screens.

Web 2.0 tools are penetrating into organizations after their successful adoption in the consumer domain (e.g., social networking; sharing of photos, videos, tags, or bookmarks; wiki-based editing). Some of these new tools and the collaborative processes that they support on the large scale are often referred to as Collective Intelligence (CI). The workshop brings together leading researchers and designers who are studying or developing CI tools aimed at workers in organizations. The goal is to further articulate the emerging research agenda for this new CSCW area and define new observed forms of CI in organization. Studies of communities, CI tools, and new methods are discussed.

Communities are social entities whose actors share common needs, interests, or practices: they constitute the basic units of social experience. With regard to communities, social capital captures the structural, relational and cognitive aspects of the relationships among their members. Social capital is defined as a set of properties of a social entity (e.g. norms, level of trust, and intensive social networking) which enables joint activities and cooperation for mutual benefit. It can be understood as the glue which holds communities together. On this panel we will discuss whether and how information technology can strengthen communities by fostering social capital.

Most of the available knowledge management systems pay little attention to two important aspects: the need of supporting emerging communities of interest together with the official organizational structure; and the need of cluing together knowledge associated with any kind of involved entity including people, communities, and informal knowledge. The MILK system enhances knowledge discovery and sharing by providing services addressing these aspects and supplying innovative interfaces and interaction styles. The goal of MILK is to become a familiar environment integrated in the every-day activities of dynamic modern workers. To meet the users' needs, the solution proposed by MILK roots in ethnographic analysis capturing the common practices within an organization.

The last decade has witnessed a growing interest in what technology can do to sustain communities. Within the Campiello project innovative information technologies have been adopted to support the dynamic exchange of experiences among people living in cities with high levels of tourism, in this way reducing the progressive diminishing of identity suffered by the local communities of these cities. The system developed has been used, for an experimental period, in a neighborhood of Venice, Italy. In the paper, we reflect on the whole Campiello experience, considering all its development phases. These reflections are organized as a set of issues that require attention, respectively, in the design and deployment of community systems, illustrated with examples from Campiello. We believe that due to the relative novelty of community systems, this type of reflection is important to inform the design of future systems such that they better fulfill their objectives and become an integral part of community practices.

Creative design is a very peculiar work practice that as not been studied very much from the viewpoint of the cooperation shaping it.In this paper we present the main findings of a case study conducted on an industrial design project with the aim of analyzing how its actors cooperate.The main findings of our field study involve: on the one hand, recognition of the major role played by physical arrangements of the work space in shaping the practice of creative designers; on the other, the distinction between the different work spaces where different phases of a design project are performed.On the basis of discussion of the above we outline the requirements for a cooperative support system for creative design as a system augmenting and multiplying the work spaces where it is performed.

This workshop aims to bring together people engaged in the study of the relationships beytween organizational learning and CSCW to present and discuss their ideas and findings. Issues will include conceptual frameworks; the role of organizational learning in getting the work done; empirical studies of the relation between organizational learning and CSCW; methods for developing applications that support organizational learning; and the relationship between studies of organizational learning and studies of organizational memory.

The debate on the language/action perspective has be!en receiving attention in the CSCW field for almost ten years. In this paper, we recall the most relevant issues raised during this debate, and propose a new exploitation of the language/action perspective by considering it from the viewpoint of understanding the complexity of communication within work processes and the situatedness of work practices. On this basis, we have defined a new conversation model, the Milan Conversation Model, and 'we are designing a new conversation handler to implement it.

The need of supporting office work with suitable computer based tools implies the investigation of the deep aspects of cooperation within the office. Cooperation, to the extent that is made up of communication and coordination, can be fully characterized under the assumption that an office is a special linguistic game, constituted by a set of rules defining the conversations possible within it, continuously changing under the perturbations created by the speech acts its member do performing the conversations. Within this conceptual context, a prototypal software package, CHAOS-1, is presented. CHAOS-1 aims both at supporting the conversations and at improving coordination of the office activities.This paper discusses CHAOS-1 with respect to similar proposals, presents its overall architecture, shows some examples of its use and sketches its new releases under development.
