Augmented Reality(AR) is one of branch of virtual reality computer graphics techiniques that places images of both the real environments and virtual graphic objects over the user's view of the world. Recently, useful apps are being developed using the AR techniques. We developed the location information service app by applying AR techniques. We used the open source 'Mixare' for AR application development for smartphones. This paper presents the design and development of the app 'Go-To-Hongdae~' that shows street views and related detailed information in real-time about buildings around our campus.

With the increased market demand for advanced specifications in smart phones, smart phones that have functions with wireless communications with high speed, cameras with high pixel and with high graphic processing ability have appeared. Furthermore, as traditional Augmented Reality technology has been practicable in mobile devices, many application's use AR technology, so AR's portability has been increased. But application with AR technology, which was implemented in smart phones has created capacity issues as applications are taking up a large portion of the memory capacity of phones. This research designed and implemented optimized AR technology by Mixare, AR open source, to solve such problems. As a result, I assured that there has been a decrease in application's memory used on the basis of mobiles.

We proposed the WSN monitoring system applied the augmented reality to visualize effectively an indoor WSN. To implement system, we used wireless sensor network, indoor location determination, location-based augmented reality technology. First, we composed the wireless sensor networks indoors and implement web server and then get data from server DB using Android phones. Then, we obtained the (x, y) coordinates using the triangulation method from RSSI of three point of the strongest signal strength of the AP's. Also, we adjusted coordinates using the Kalman filter. Finally, we inserted the adjusted coordinates to the latitude and the longitude of the Mixare that use the GPS signal, and we got location of user and wireless sensor in the server DB. After that, we implemented augmented reality system using the android phone and wireless sensor location and data and real life image.

Recently, with the popularization of smartphones, augmented reality has become even more familiar to the public as an application that can provide realistic images as a tool for location-based services. Therefore, as a location-based application for smartphones that is appropriate for the application of augmented reality technology, the study develops a golf information system. Golf is the sport for which we should exactly know the accurate shape or distance to the destinations or obstacles, so the sport is suitable for applying the augmented reality technology. Even though the sport of golf has constantly increasing population to play it with the popularization of it, presently released golf-related smartphone apps are established as 2D images or in GPS basis; thus, they lack a sense of realism unfortunately. Thereupon, this study develops a golf information system by modifying and complementing usefully Mixare, the open source for augmented reality, for the sport of golf into an augmented reality-based system that can provide various information according to the actual environment of the golf course and describes how to apply it actually to the golf course.
