How do archaeologists work? A multimedia digital object to learn their investigation process
No full textThe aim of the CHAT ("Cultural Heritage fruition & e-learning applications of new Advanced (multimodal) Technologies") research project was to provide on smartphones context-sensitive multimedia services accessible through several interaction modalities. The multimedia content of such services was implemented as Digital Objects managed by the Fedora web service. In this paper, we present a multimedia digital object that, through images, videos, 3D reconstructions, sounds, informs people about the scientific value of the archaeological investigation and about the complexity of the overall archaeological research process. Archaeologists follow a rigorous method, called stratigraphic excavation, to reconstruct the past civilizations lifestyles. People tend to think that the archaeologist work consists only in the excavation and research of valuable elements, while it has its scientific rigor. By exploiting the CHAT infrastructure, the multimedia digital object about the archaeologist work can be accessed in difTerent context on several device
Advanced interaction paradigms to define smart visit experiences in the internet of things era
No full textThe growing spread of smart objects is changing the way humans interact with technologies since the interaction they propose is more and more physical and less virtual. From an HCI perspective, one of the most interesting aspects regards how non-technical end users can program the behavior of such smart objects. This poster presents an ongoing project on three novel interaction paradigms that support the creation of smart visit experiences. Copyright is held by the author/owner(s)
CHAT – Towards a general-purpose infrastructure for multimodal situation-adaptive user assistance
No full textOn the Importance of the User Interface for E-Learning Systems Quality
No full textE-learning is the most recent way to achieve distance education, carried out by distributing learning material and processes over the Internet. This paper refines the concept of quality of e-learning systems and proposes a new framework, called TICS (Technology, Interaction, Content, Services), which focuses on the most important aspects to be considered when designing or evaluating an e-learning system. Our proposal emphasizes user-system interaction as one such important aspect. Based on TICS framework, design guidelines and evaluation patterns are derived
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

No full textA Biofeedback System to Compose Your Own Music While Dancing
No full textBrain Computer Interfaces can enable engaging interactions between different art forms such as music, dance, painting. Building on this, we present a demo of a biofeedback system: a dancer wearing a NeuroSky headset adapts her performance according to the music she listens to. The same music has been generated by a music-composition software depending on her own real-time mental status represented by different fluctuations of some EEG parameters
