Designing for user confidence in intelligent environments

Intelligent environments aim at supporting and assisting users in their daily activities. Their reliability, i.e., the capability of correctly accomplishing the intended tasks and of limiting or avoiding damage in case of malfunctions, is essential as for any user-facing technology. One aspect of reliability, often neglected, is guaranteeing the consistency between system operation and user expectations, so that users may build confidence over the correct behavior of the system and its reaction to their actions. The paper will review the literature concerning methodologies and tools that directly involve users and have been specifically applied or adopted for intelligent environments, throughout the entire design flow—from requirements gathering to interface design. The paper will then propose, building on top of the previous analysis, a set of guidelines that system designers should follow to ensure user confidence in their intelligent environments.

The art of video MashUp: supporting creative users with an innovative and smart application

In this paper, we describe the development of a new and innovative tool of video mashup. This application is an easy to use tool of video editing integrated in a cross-media platform; it works taking the information from a repository of videos and puts into action a process of semi-automatic editing supporting users in the production of video mashup. Doing so it gives vent to their creative side without them being forced to learn how to use a complicated and unlikely new technology. The users will be further helped in building their own editing by the intelligent system working behind the tool: it combines semantic annotation (tags and comments by users), low level features (gradient of color, texture and movements) and high level features (general data distinguishing a movie: actors, director, year of production, etc.) to furnish a pre-elaborated editing users can modify in a very simple way.

Where Have You Ended Up Today? Dynamic TV and the Inter-tainment Paradigm

Traditional TV was based on a time-dependent and passive paradigm of use: the availability of audiovisual contents was pre-defined by a rigid scheduling, and users role was to choose among limited alternatives. A potential for active TV experience is now available: users should be allowed to access contents that fit their attitudes at any time, while being encouraged to discover new domains of interest. This paper outlines the basic elements of the new Inter-tainment paradigm, which builds on an active role of the user and on attitude-centred fruition. Successful applications of the new paradigm require flexible and reconfigurable structures of navigation: the development stages of an Inter-tainment system are reported here.

Interacting with a Social Web of Smart Objects for Enhancing Tourist Experiences

In this paper we introduce the idea of interaction with networks of socially intelligent objects as a way of supporting tourists and introducing them to the culture of a territory and as a way of maintaing the cultural heritage of a territory alive. We illustrate this idea with an application we designed in the field of gastronomy. Socially intelligent objects are able to maintain and aggregate knowledge about themselves and their world and are able to establish social relations with other objects and people. In this way they become hubs which allow tourists to get in touch with the world of the objects which is made of a territory, its culture and traditions, people and other objects. We support natural forms of interaction without requiring any electronic infrastructring of the objects. In particular, we designed an interaction paradigm supporting a playful enhancing experience when interacting with objects. We also support a continuum of experience in the real and virtual world.
