Interacting with social networks of intelligent things and people in the world of gastronomy

This article introduces a framework for creating rich augmented environments based on a social web of intelligent things and people. We target outdoor environments, aiming to transform a region into a smart environment that can share its cultural heritage with people, promoting itself and its special qualities. Using the applications developed in the framework, people can interact with things, listen to the stories that these things tell them, and make their own contributions. The things are intelligent in the sense that they aggregate information provided by users and behave in a socially active way. They can autonomously establish social relationships on the basis of their properties and their interaction with users. Hence when a user gets in touch with a thing, she is also introduced to its social network consisting of other things and of users; she can navigate this network to discover and explore the world around the thing itself. Thus the system supports serendipitous navigation in a network of things and people that evolves according to the behavior of users. An innovative interaction model was defined that allows users to interact with objects in a natural, playful way using smartphones without the need for a specially created infrastructure. The framework was instantiated into a suite of applications called WantEat, in which objects from the domain of tourism and gastronomy (such as cheese wheels or bottles of wine) are taken as testimonials of the cultural roots of a region. WantEat includes an application that allows the definition and registration of things, a mobile application that allows users to interact with things, and an application that supports stakeholders in getting feedback about the things that they have registered in the system. WantEat was developed and tested in a real-world context which involved a region and gastronomy-related items from it (such as products, shops, restaurants, and recipes), through an early evaluation with stakeholders and a final evaluation with hundreds of users.

Toward a social web of intelligent things

In this paper we introduce the notion of “Social Web of Intelligent Things” (SWIT hereafter) as a an evolution of both the “Web of Things” and “Smart Objects” paradigms. In a SWIT, things become entities capable of an intelligent and social behavior. On the one hand, things maintain and socialize knowledge and can interact and communicate with people; on the other, “social” networks of people and things arise as a result of this interaction. SWIT is an evolution of social media that goes beyond the desktop paradigm and is a way of bridging the gap between real-life and virtual experiences. Interactions between people and things happen naturally in real life, augmenting and enhancing peoples experiences. We claim that SWITs are a challenging area of research and application for Artificial Intelligence in the context of the Future Internet. The paper provides a characterization of SWITs, discussing the ingredients that are needed to create a SWIT; it introduces a framework for building SWITs and briefly presents an instance we developed and tested with users. In the paper we claim that many areas of Artificial Intelligence can contribute to the is framework, which in turn can stimulate research in these areas and on their integration.

Eliciting Affordances for Smart Objects in IoT Era

In this paper we suggest a design research method for eliciting affordances and new meanings for Smart Objects in the Internet of Things Era. After an introduction to the topic and the description of some open issues, we propose to adopt a Critical Design approach, where the role of Ambiguity is twofold: on the one hand, it is the objective of the observation for defining a set of ambiguous objects or affordances; on the other hand, it is the result of a design conceptualization of smart objects aiming at provoking cognitive dissonance and finalized to understand people adaptation processes and behaviors.

Supporting content discovery and organization in networks of contents and users

The design of approaches for supporting the user in the navigation of a variety of contents is an interesting area of research with many potential applications. In particular, interactive television (iTV) offers users the opportunity of accessing a huge amount of contents, ranging from general to specialized ones. As a consequence, the exploration of such contents must be supported in some way. In this paper, we present an innovative approach that integrates some recent methodologies and technologies developed in different areas of Artificial Intelligence and the Web: user-model-based adaptation, social networking, semantic annotation, and content sharing. We show how the integration of these technologies can provide interesting opportunities for a new approach to content navigation and discovery based on the possibility of exploring personalized networks of contents, users and concepts. Also, we focus on the specific goal of designing a platform for accessing iTV contents with the aim of providing the user with many alternative ways of exploring and discovering potentially interesting videos. After discussing the application, integrated in a project by Telecom Italia for a new paradigm of iTV, we preset the architecture we designed for integrating the methodologies discussed above.

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.

Designing for smart cities: connecting and binding citizens to urban spaces through a new wearable interactive system

In this paper we present a wearable interactive system that has the aim to strengthen the bond between individuals and urban spaces, leveraging the personal memories of the citizens.

An ethnographic study of packaging-free purchasing: designing an interactive system to support sustainable social practices

ABSTRACT Consumption practices show a strong presence of crystallised social understandings, organising rules and permanent ways of acting that prevent individuals from changing towards more sustainable habits. Over the years, human–computer interaction research tried to help people engage in sustainable lifestyles promoting the health of the Earth. However, by favouring an individualistic and rationalistic approach to design, these attempts often lacked a deep understanding of how individuals are intertwined with social dynamics and organisational structures that might determine their actions. In this article, we aim at exploring novel solutions to support people’s sustainable habits, by focusing on their everyday purchases. Using an ethnographic method grounded in the social practices approach, we analyse the value that individuals ascribe to activities and objects that seem already addressed to sustainable consumption: the packaging-free purchasing practices. Starting from the insights gathered from this research, and leveraging the opportunities opened by the 3D printing technology, we design an interactive system with the aim to break the old buying routines and support the reuse of containers.

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.

iDYNamicTV: a social adaptive television experience

The paper presents an approach to merge Web 2.0 and adaptation with TV contents in order to enrich the user experience. We present iDYNamicTV, a social Web-based recommender system dealing with multimedia contents. iDYNamicTV is part of a larger project by Telecom Italia (DynamicTV) for enhancing user experience in TV fruition. The goal of iDynamicTV is to provide facilities to entertain when exploring and discovering media contents on the Web using a computer interface.
