A common cause for inconsistent accessibility in the design of ICT applications is that designers work to develop optimal and satisfactory interfaces but they do not take care to comply with all users’ needs and possibilities to access. The study presented in this paper stems from a lack of published evidence able to support designs in developing a...

Our research work describes a team of human Digital Twins (DTs), each tracking fitness-related measurements describing an athlete’s behavior in consecutive days (e.g. food income, activity, sleep). After collecting enough measurements, the DT firstly predicts the physical twin performance during training and, in case of non-optimal result, it sugge...
Article
The society we live in today is frequently referred to as knowledge society or knowledge economy, and the futurist Toffler (1981) refers to it as ‘The Third Wave Society’ by arguing it is as distinct as the previously much longer lasting agricultural society and industrial society. Toffler predicted the trajectory technology and society would take...
