No full textHow 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)
Metamorphic data sources: A user-centric paradigm to consume linked data in interactive workspaces
Full text linkIn the last years, the debate about the success or failure of Linked Data (LD) has been growing. Despite the ever-increasing number of available ontologies and LD datasets, there is still a limited number of applications to let people benefit from using this huge amount of data. Some evident problems relate to the limited opportunities offered to the end users, i.e., people without skills in computer programming, to access, navigate and visualize LD. Tools supporting such tasks typically do not consider the end users’ needs; even when they provide abstraction mechanisms to avoid programming, they do not properly hide the complexity of getting oriented into the plethora of available resources. Thus, they end up to be inadequate to real daily scenarios. In this paper, we propose an approach that enables end users to create visually entry points, which we call Metamorphic Data-Sources (MDSs), to query and visualize the LD without requiring any prior knowledge of semantic Web or visualization technologies. Through the MDS visual paradigm, end users can tailor ad-hoc data sources to retrieve information on topics they are interested in. The MDS creation process is also driven by a quality model that further helps users select LD elements potentially free of data quality problems. The paper also reports on the results of a user study that we conducted to assess the validity of the MDS paradigm with respect to the user needs
Recruitment Chatbot Acceptance in Company Practices: An Elicitation Study
No full textRecruitment bots are becoming increasingly popular, but there is limited research on how human-centered design principles guide their development. This study aims to address this gap by providing insights into the design of recruitment chatbots that prioritize human-centered principles and improve the overall experience for their final users. Semi-structured interviews with 4 recruiters and 6 job seekers were conducted to investigate their experiences with recruitment procedures and their perspectives on how chatbots could influence their experiences. The study revealed insights related to the impact of chatbots on the user experience and their acceptability in the context of human-centeredness, thus contributing to the development of next-generation, human-in-the-loop chatbot recruitment systems
On 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
Privacy Design Strategies and the GDPR: A Systematic Literature Review
No full textArticle 25 of the GDPR states that data collection, processing and management measures should be implemented following tṇhe privacy by design and privacy by default paradigms. This paper presents a systematic literature review to identify useful guidelines to support the development of GDPR-compliant software. Selected papers are categorized under 8 different data-oriented and process-oriented strategies and their contributions are reported. Future activities will highlight the HCI community’s attitude towards these new technical and organizational approaches in order to bridge the identified gaps and shortcomings
