Michelle Henning: Museum, Media and Cultural Theory

2011

La recensione di Museum, media and cultural theory, primo risultato pubblicato relativo alla ricerca condotta da Michelle Henning sui media comunicativi e sulla loro applicazione all’interno dei musei, mira ad analizzare gli aspetti contenutistici del testo, a contestualizzarne il contenuto nei filoni teorici di riferimento e a sottolinearne l’importanza nell’ampio dibattito attuale sull’argomento cui fa riferimento, le nuove strategie di esposizione nei musei.

Musei e nuove tecnologie per allestire

2011

In recent years, the application of new technology has become more widespread in expanding areas. In the field of cultural heritage, this technology has brought important changes to traditional systems of protection, management and enhancement; there are new languages for communicating the different values of cultural heritage, contributing to a more extensive dissemination of culture assets.The application of new media in indoor museums is changing the way of presenting objects and communicating their meaning, and renders the visit more enjoyable, involving and exciting.However, the excessive use of these tools can become overwhelming when compared to the objects themselves, transforming t…

Tecnologie digitali per la valorizzazione del patrimonio culturale. La rappresentazione di beni non accessibili

2017

Il contributo rientra nel filone delle sperimentazioni di comunicazione multimediale e di ricostruzione virtuale di architetture e frammenti urbani. Il lavoro presenta i risultati di alcune applicazioni digitali che adoperano il linguaggio multimediale per consentire la fruizione virtuale di siti per diverse ragioni non accessibili, per raccontare un percorso reale o concettuale. I casi studio analizzati si configurano quali possibili prodotti strategici di divulgazione e comunicazione per la conoscenza e la comprensione del patrimonio culturale e per la veicolazione di contenuti scientifici. The contribution is part of the study and experimentation of multimedia communication, virtual anal…

Searching the internet for learning materials through didactic indicators

2007

Internet offers a huge amount of didactic materials that can be used in creating new online courses. However, those materials need a deep analysis to understand their context and contents before their potential use. As a consequence, the search of didactic material in internet is often quite tedious and time consuming so the searcher usually limits his/her analysis to the first found web pages . To help users in finding efficiently and timely the most appropriate online materials, we have developed a system, called SAXEF (System for Automatic eXtraction of lEearning object Features), that is capable to automatically extract the didactic indicators (a sort of DNA) of any web page (or group o…

Flexible and Modular Support for Multicast Rate Adaptation in WLANs

2013

The flexibility and virtualization capabilities provided by wireless cards have received significant attention as a means to reduce development costs. In this paper we present a modular architecture that exploits the features provided by emerging PHY and MAC implementations to rapidly develop new rate adaptation algorithms for multicast trans- mission in wireless LANs. We validate our solution by developing three rate adapta- tion algorithms that use an innovative sensing mechanism to evaluate the frame recep- tion correlation of the members of the multicast group. The experimental results obtained on a real-life testbed show that our solutions permit to increase the performance of multicas…

A Dynamic System for Personal Communications: The Opportunistic Chat

2007

most of currently available inter-personal instant messaging systems are client-server based. Users of such systems need to be connected to some centralized entity which goal is to supply them with information needed to make the communication possible, such as the list of connected users, their status, and the address of their devices. Our proposed system for an “Opportunistic Chat” allows people to exchange written messages over Bluetooth and (if necessary) TCP/IP connections, with no need of any kind of centralized entity, by using ad-hoc procedures, automatically selected and operated. Such system can be accessed almost from any kind of device, either mobile or not, ranging from personal…

Mobile Interface for Content-Based Image Management

2010

People make more and more use of digital image acquisition devices to capture screenshots of their everyday life. The growing number of personal pictures raise the problem of their classification. Some of the authors proposed an automatic technique for personal photo album management dealing with multiple aspects (i. e., people, time and background) in a homogenous way. In this paper we discuss a solution that allows mobile users to remotely access such technique by means of their mobile phones, almost from everywhere, in a pervasive fashion. This allows users to classify pictures they store on their devices. The whole solution is presented, with particular regard to the user interface impl…

Recognition of Human Actions Through Deep Neural Networks for Multimedia Systems Interaction

2019

Nowadays, interactive multimedia systems are part of everyday life. The most common way to interact and control these devices is through remote controls or some sort of touch panel. In recent years, due to the introduction of reliable low-cost Kinect-like sensing technology, more and more attention has been dedicated to touchless interfaces. A Kinect-like devices can be positioned on top of a multimedia system, detect a person in front of the system and process skeletal data, optionally with RGBd data, to determine user gestures. The gestures of the person can then be used to control, for example, a media device. Even though there is a lot of interest in this area, currently, no consumer sy…

Keyword Based Keyframe Extraction in Online Video Collections

2015

Keyframe extraction methods aim to find in a video sequence the most significant frames, according to specific criteria. In this paper we propose a new method to search, in a video database, for frames that are related to a given keyword, and to extract the best ones, according to a proposed quality factor. We first exploit a speech to text algorithm to extract automatic captions from all the video in a specific domain database. Then we select only those sequences (clips), whose captions include a given keyword, thus discarding a lot of information that is useless for our purposes. Each retrieved clip is then divided into shots, using a video segmentation method, that is based on the SURF d…
