ABSTRACT
Virtual tours are tools that could be effectively used in many different contexts. The COVID-19 pandemic has let emerge how they can be useful and efficacy in those situations where it is not possible to access physical places and attend events. Besides that, they can be used for several goals in different contexts. In fact, in simple words, virtual tours are essentially based on using 3D images and videos, letting the users interact with the virtual environment and its points of interest through them, emphasizing the need for navigation and orienteering mechanisms within the virtual environment. Due to these characteristics, virtual tours represent digital barriers affecting users with disabilities, in particular those people with visual impairments. This paper presents an innovative solution we have adopted by designing and developing a prototype devoted to exploring a University Campus, with accessibility in mind. A preliminary evaluation has been conducted, and the obtained results are presented in the paper, which discusses some potentialities and limitations that emerged, © 2023 IEEE.
ABSTRACT
The tremendous CoVid-19 outbreak has had a significant impact on the lives of people anywhere in the world. Several approaches have been presented with the aim of helping in limiting and mitigating the effect of CoVid-19 infections. This paper proposes a system that exploits Internet of Things (IoT) and Data Visualization to monitor the flow of people in buildings, with the aim of providing policymakers with a tool that visualize and highlight critical issues. The case study considered is a Smart University Campus located in Cesena, belonging to the University of Bologna. © 2021 ACM.
ABSTRACT
Sentiment analysis, social networks analysis, and social media sensing are becoming important tools to extract meaningful information from text, adopted in several contexts, ranging from social interactions, touristic activities, shopping and e-commerce, to name a few. In particular, the current CoVid-19 quarantine the world is witnessing has shown the potential of such tools as a way to monitor and understand people's mood and feelings, in a time where people are resorting, more than ever, to social networks to engage and communicate with others. Indeed, when performing social network content analysis, privacy is a major concern. On the one hand, privacy issues and international laws and acts drive such analysis (e.g., GDPR), with the aim of protecting persons' privacy and security. On the other hand, these can limit somehow such activities. Hence, a precise and accurate identification of the strategies to adopt should be done to balance privacy issues and sentiment analysis activities. Taking into account the requirements of a Urban Innovation Action project, which is based on the active involvement of citizens, this work aims to describe limitations and potentialities of social networks monitoring and analysis to understand users' mood about the project actions adopted in the city of Ravenna (in Italy) to improve specific districts.
ABSTRACT
"Covid-19 is a virus developed to rule the world" is just one of the many fake-news published on the Web. In this pandemic period, the Web is flooded with real news, allegedly true or blatantly false. To understand how fake news is affecting the Covid-19 perception, we selected 40 news (either true or fake) related to the origin, diffusion, treatment and effects of Covid-19 and we asked 293 volunteers to express their opinion on the truthfulness of the news. Then, we propose an Awareness index to compute knowledge degree of the volunteers. The results highlight a large ignorance on medical news, ignorance that goes beyond educational background. The study highlights the need for Health Institution to enter social media platforms in order to clearly explain what is true and what is false on Covid-19.
ABSTRACT
The COVID-19 pandemic has dramatically changed every aspect of our professional and private life. It forced us to stay at home and it gave unprecedented power to technology. In this paper we focus on the emerging technology of smart speakers (e.g., Amazon Echo Plus, Google Home, etc.) and, through a developed questionnaire, we investigate how people use these devices. In particular, we analyze whether the human behavior has been affected by availability of these smart speaker. Results showed that the usage of these devices did not increase during lockdown, but it highlighted the presence of some privacy issues that might represent a burden to the diffusion of this type of technology. © 2020 ACM.
ABSTRACT
Among all the others, one of the groups of persons most affected by the restrictions applied to contrast Corona-Virus spread is surely represented by children. In particular, closing school has been an action applied by several countries (195 at the beginning of April 2020), involving 1,600,000,000 students all over the world. In Italy, distance learning activities have been adopted all over the country, at each educational stage, but with substantial differences (i.e., in terms of modalities and digital platforms). With the aim of investigating the most adopted technologies, didactic methodologies, as well as the impact on schools population, we have involved families of more than 1,000 Italian students, asking them to fill a survey. This paper presents the analysis of the results we have obtained, focusing on a delicate group of students: the ones attending primary schools, where kids learn fundamental knowledge and basic skills. © 2020 ACM.
ABSTRACT
Recently, there has been a lot of talk about Frugal services, that is, services that use existing technologies for a purpose other than the one for which they were designed. In this paper, we study whether the IoT wearable environment can be a fertile ground for the production of Frugal services. Through a real-world study, we investigate whether these devices are widespread, if there are obstacles that limit their diffusion, if the sensors they are equipped with are deemed reliable and, finally, if people who own them have an altruistic propensity or not. The results, from the frugal point of view, are encouraging: the IoT wearable environment seems to be pervasive enough and ubiquitous, without great obstacles for their adoption. The provided sensors seem to be generally reliable, whereas the altruistic propensity might be questioned: in general, people are not inclined to share, but if the goal is clear (in our case we hypothesized a fight against Covid-19), altruistic propensity grows a lot. © 2020 ACM.
