Mobile indoor navigation system in iOS platform using augmented reality

Usage areas of mobile phones have increased in the last 10 years. Although there have been improvements in many areas, most of the developments are in the field of positioning systems. Although the peoples lives continue in indoor environments, location-based information system receives data from the satellites, which can detect a persons location in outdoor areas. In indoor areas, satellite signals can cause false information or can be interrupted by the objects in the area. In this study, an indoor navigation system has been designed and developed that only uses the accelerometer, the camera and the compass components on the phone and does not require satellite signals for positioning. To provide independence from the map in this application, augmented reality is applied during the routing process by utilizing built-in camera of the phone and no map is used.

Mobile based optical form evaluation system

Ulkemizde ve dunyadaki egitim sistemlerinde gerek ogrencilerin basarilarinin degerlendirilmesinde gerekse ogrenci seciminde coktan secmeli siklar iceren optik formlar cok sik kullanilmaktadir. Optik formlar optik okuyucu cihazlar sayesinde optik isaret tanima teknikleri kullanilarak degerlendirilmektedir. Bu tip cihazlarin pahali olmasi, bu cihazlara erisimin sinirli olmasi ve degerlendirme sonuclarini bekleme suresinin uzun olmasi hem buyuk sehirlerde hem de tasrada calisan egitimcilere zorluk cikarmaktadir. Bu calismada egitimcilerin sahip olduklari akilli telefon ya da tabletleri araciligi ile bir mekâna ya da optik cihaza bagli kalmadan, hizli bir sekilde ogrenci cevap formlarini degerlendirebilecekleri mobil bir yazilim gelistirilmistir. Optik form tanima, okuma ve degerlendirme islemi egitimcinin mobil telefonu ya da tableti araciligi ile cektigi ogrencinin cevap formu goruntusu uzerinde yapilmaktadir. Gelistirdigimiz Android tabanli mobil uygulama kullanici dostu bir arayuze sahip olup basari orani yuksektir ve bu alanda mobil ortamlarda calisan ilk uygulama olma ozelligini tasimaktadir.
