This paper introduces the studies on Horizontal Coverage Pattern (HCP) for Bus Detection Devices (BDD). BDD is a device which functions to assist blind people in detecting bus at the bus stop. The prototype of BDD was developed using RFID technology which consists of RFID reader, UHF passive tags and computer. Various testing and experiment have been done to improve the functionality of the device...
A Radio-Frequency Identification Walking Stick (RFIWS) system was developed to assist the blind walking. The RFIWS system used Radio Frequency Identification (RFID) technology to enhance the traditional walking stick. In RFIWS system, the passive RFID tag and circular polarization RFID antenna has been used. In order to optimize the RFIWS functionality, an investigation on effect of antenna positions...
