Development of Qiblat Finder Assisted Device for Visual and Hearing-Impaired Person

Abstract

For the visual and hearing-impaired person, finding intended direction would be a challenging task due to their inability to sense effectively with their eyes and ears. This study aims to develop a prototype development of a smart qiblat finder to help disabled people finding direction anywhere independently. This smart qiblat finder are developed by using Arduino UNO as microcontroller, compass sensor and Global Positioning System (GPS). To determine the qibla direction, latitude and longitude data form by GPS module while the compass module used to show the qibla direction. As for the positioning of the qibla, the prototype can detect qibla at range 291° until 293° angle to match the place of data collection. Once detected, indicators (buzzer, vibration motor and LEDs) will alert the user with continuous sound, vibrations and lighting sequences. The prototype was tested indoor and outdoor at few locations in university campus and Seksyen 7 Shah Alam Mosque. The result showed high accuracy (99.3% to 100%) in detecting the direction of qibla and successfully alerted the user through buzzer sound and vibration and LED.
