In recent years, mobile and ubiquitous computing has emerged in our daily lives, and extensive studieshave been conducted in various areas using smart devices, such as tablets, smartphones, smart TVs,smart refrigerators, and smart media devices, in order to realize this computing technology. Especially,the integration of mobile networking technology and intelligent mobile devices has made it possible todevelop the advanced mobile distance learning system that supports portable smart devices such assmartphones and tablets for the future IT environment. We present a synchronous mobile learningsystem that enables both instructor and student to participate in distance learning with their tablets.When an instructor gives a lecture using a tablet with frontfacecamera by bringing up slides andmaking annotations on them, students in the distance can watch the instructor and those slides withannotation on their own tablets in real time. A student can also ask a question or have a discussiontogether using the text chat feature of the system during a learning session. We also show the userevaluation of the system. A user survey shows that about 67% are in favor of the prototype of thesystem.
