MoCHA: Augmenting pervasive displays through mobile devices and web-based technologies
Elena Oat, Mario Di Francesco, Tuomas Aura · 2014
In this article, we propose a web-based system, called MoCHA display, for rich interactions between pervasive displays and users with a mobile device. Our scheme consists of a web-centric architecture, in which both the screen and the mobile device simply need to run a web browser. Our contributions are twofold. First, we develop a distributed architecture based on modern web technologies and cloud computing to provide rich interactions between users equipped with a mobile device and pervasive screens. Second, we devise a mechanism for practical and secure binding of screens and mobile devices based on their proximity. We present a prototype of the system as well as some preliminary results about its usability and performance.
