Abstract-In this paper, the potential of contextual communications with mobile technologies is explored. Contextaware applications allow relevant information and services to be delivered to users at a given time. One of the two objectives of our work is to propose a generic user's context model for mediated communications. This model is based on six dimensions: User's profile, Activity, Device, Environment, Location and Time. In addition, to show the utility and to validate the proposed approach, we designed a prototype named MeCoCo (Mediated Contextual Communications) with a specific interface promoting the search of interesting contacts and messages. The MeCoCo prototype illustrates the power of contextual information.
Abstract-When teachers are involved in synchronous tutoring carried out on a practical work, they need overall but semantically relevant information in order to better manage learners' activities. This information, given through indicators, enables teachers to quickly detect learners' critical situations. Thus, relying on indicators, they can intervene and choose the better remediation strategies to solve these critical situations. In this paper, we propose a way to identify, define and calculate indicators through UTL and DCL4UTL. We also conducted experimentations in order to examine the benefits of the use of indicators during practical work sessions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
