Assistive Prayer Technology: Developing a Rakaat Tracking System for Elderly Muslims with Physical Limitations

Abstract

Elderly Muslims who experience memory decline and physical limitations often struggle to accurately track raka’at during prayer. This study proposes the design and development of a portable raka’at monitoring system intended for elderly users. The system integrates pressure sensors to detect prayer movements and a Bluetooth module to facilitate data communication between the microcontroller, sensor, and mobile application. This study explores the integration of an STM32 microcontroller into the system to ensure its feasibility. It also incorporates Shariah compliance through consultations with fiqh Islamic scholars to ensure the device aligns with religious law. The prototype involves two phases of development and requires validation of both its mechanical design and usability. This study contributes to assistive religious technology by enabling elderly Muslims to practice their religious activity with greater confidence.
