Concurrent with the more widespread usage of smart devices, mobile users' desires are becoming much more complex. Most IT experts insist that smart devices should have additional functions to satisfy these requirements. In particular, research has concentrated on LBS (Locationbased Service), because it is considered one of the most common mobile service types. Generally, Wi-Fi has a critical limitation for use for LBS services, because it requires new network connection points whenever its location (Network Zone) changes. Unfortunately, GPS also has a systematic problem in providing LBS service in the indoor environment, because of its inaccuracy in processing data. So, to redress these limitations, iBeacon technology has been designed, and is currently used for LBS service instead of Wi-Fi or GPS. By using iBeacon, which is based on Bluetooth 4.0 LE technology, we propose a M-SAS (Mobile-Subway-Alarm-Service System) that could accurately and timely provide its users with various mLBS (micro LBS) services, such as current user location, and subway arrival time.

With the advent of smart phones recently, users have experienced a new way of communicating using a smart phone without the constraints of time and space. As a result, users are ubiquitous around the user's own resources and a variety of natural interaction that was required. In particular, the interaction between the user and the content in the virtual reality and augmented reality, otherwise your content or service in the real world and the virtual direct and intuitive interaction can be. In this paper, we use Augmented Reality smart-phone sitting in the subway system that allows people to know the arrival station is designed to offer.
