Ubiquitous learning a new challenge of ubiquitous computing: state of the art

New technological developments made interaction possible with computer systems and applications anywhere and anytime. These applications must be capable to be adapted to the user as a person and his current situation. In 2021, following the pandemic COVID-19, learners across the country have had the opportunity to experience online modes of learning. Therefore, in the current study, an attempt has been carried out to develop a new paradigm of learning, known as ubiquitous learning or U-learning (UL), which is supported by ubiquitous computing technologies. Ubiquitous learning has become an economic and scientific issue, especially with the COVID-19 pandemic. Furthermore, the paper also aims to provide fundamental information related to U-learning as the definition and characteristics of U-learning and the areas of the most common applications in our daily lives. Finally, U-learning applications in the different domains are explained and compared to further improve the understanding of the concept of U-learning and the importance of using UL in our lives.
