Abstract:In last decade, expansion of mobile phones increased people's usage of these devices. In parallel with the increasing usage rate, the number of developed applications increased for mobile phones. Thanks to mobile phones, many different fields have been affected. However, the biggest contributions of mobile phones are orientation and location finder services. Although people spend major time of their life in indoor areas, usage of navigation systems must be outdoors since these systems get coordinate information from satellites. In indoor areas, walls, and any object in a building cause wrong results or block navigation systems. In this study, orientation and location finder services for indoor navigation will be done by using accelerometer, compass and camera that have been already included in the phones and augmented reality technology for iOS based mobile phones and locations will be provided thanks to beacon Bluetooth devices.

“…In his paper, he explores: the iGPS system (Krautschneider, 2006) that uses a transmitter of rotating fan-shaped infrared laser planes that is capable of a mm-level accuracy; the Locata System (Barnes, Rizos, Kanli and Pahwa, 2005) which is a positioning system that uses radio signals transmitted in the 2.4 GHz band, to be able to penetrate the inside of buildings, by transceivers placed within a range of several hundred meters up to several kilometres and with a sub cm precision; and the Cricket (Priyantha, 2006), Active Bat (Hazas and Hopper, 2006), and Dolphin system (Fukuju, Minami, Morikawa and Aoyama, 2003), which are ultrasonic positioning systems that have beacons emitting both ultrasonic pulses and radio frequency messages, and receivers that can use the difference in the arrival of both the signals to calculate de distance from each beacon and triangulate their position. Kalkusch et al (2002) present a mobile augmented reality application where the user has a helmet with a mounted camera that detects and tracks well known markers, previously scattered around the environment. This tracking allows the system to identify the position and orientation of the user.…”

Abstract:Although location based applications have been gaining popularity, most positioning devices do not work when in an indoor environment, hindering the development of both mixed and indoor location based applications. In this paper we present a point of interest aware application that shows information to the user that is dependent on his indoor location. To be able to detect the user's position, we propose a technique, based on the detection of footsteps, and the direction in which they were taken, to be able to calculate the position of the user inside a building. To improve the accuracy of the system, we use information about the buildings floor plan to create a graph that can be used to correct invalid movements.
