Title: An Online Education System to Produce and Distribute Video Lectures
Journal: Mobile Networks and Applications
Date: June 2020
DOI: DOI 10.1007/s11036-019-01236-4
Abstract: Nowadays, the term “student” embraces people with different needs and lifestyles (e.g., people with part-time or full- time jobs, people with some forms of disabilities, etc.) and, in the attempt to reach out to these students, many educational institutes are recording and releasing classroom lessons. In this paper, we share our experience building ONELab, a system designed to capture, record, edit and stream video lectures. ONELab was designed to provide flexibility to educational contents (i.e., no time and geographical constraints) and to improve the students’ learning process. Moreover, the system had to be scalable and cost-effective. The system has been used in the 2017-18 Academic Year to manage the 49 courses offered by the five-degree programs available at our Department. In numbers, it supported 1,251 students and produced 1,376 video lectures (for a total of 2,064 hours). The usage analysis showed that students want to adapt the learning process to their lifestyle and showed that students who used ONELab acquired more credits (+119%) and had better grades (+9.4%) than those who did not use the system.

Title: On the Usage of Smart Speaker During the Covid-19 Coronavirus Lockdown
Conference: Smart Objects and Technologies for Social Good
Date: September 2020
DOI: 10.1145/3411170.3411260
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.
