Conference Object An algorithm for passive RFID based location estimation;(IEEE Computer Society, 2014) Ozyurt,E.; Aydin,E.; Yapici,A.C.In this study, an indoor localization system is developed for the mobile robots. The localization system consists of a passive RFID tag and a reader. The passive RFID tag is placed on the robot and reader antennas are spatially dispersed into the room. For the localization, Selective Adaptive Weighted Centroid Localization (SAWCL) algorithm is used. Performance of the localization system is evaluated for the different tags. © 2014 IEEE.Conference Object Citation - Scopus: 14An indoor navigation aid designed for visually impaired people(IEEE Computer Society, 2008) Öktem,R.; Aydin,E.; Çaǧiltay,N.E.This work introduces the hardware architecture and general principles of a portable indoor navigation system for guiding visually impaired people. It operates through wireless communication between a compact hardware interface unit carried by the user, a central processing unit and an active RFID unit. The RFID unit collects signals as regard to the position of the user, the central system processes those signals to estimate the position of the user and proposes a route and direction for the user to follow, whereas hardware interface unit provides interaction. The orienteering of the user is obtained by a tactile compass. © 2008 IEEE.
