In the ubiquitous Internet, human mobile-web interactions can be evaluated with real-time analysis of time-based usability and accessibility with the different types of mobile Internet devices including smart phones (e.g. iPhone, Android phone, etc.). A ubiquitous mobile-web interaction server, accessible with a variety of mobile Internet devices, could be a unified estimation hub in real-time analysis of human-centric mobile-web interactions. We propose the real-time analysis scheme based on real-time estimation of time-based usability and accessibility for human mobile-web interactions with a name-based directory server for social networking in the ubiquitous Internet environment. We present an implementation of a ubiquitous mobile-web directory service and discuss our approach with some empirical results.
