Development of a Technical Device Named GPS Based Walking Stick for the Blind

Abstract

Generally, blind people use a traditional cane (known as white cane) for moving from one place to another. Although, white cane is the international symbol of blindness, it could not help them to detect place and to avoid obstacles. In this paper, we represent a model of walking stick for blind people. It consists of GPS module, GPS Antenna, Arduino, ultrasonic sensor and buzzer. This stick can detect place and obstacles. Position detection part is done with GPS module and GPS antenna. Ultrasonic sensor is used for detecting obstacles. Here, the buzzer produces two types of sound. When the blind reaches to his destination, buzzer buzzes continuously. When the blind faces any obstacles, buzzer buzzes with interruption. By discovering these two types of sound, blind can be confirmed about his destination and also can avoid obstacles in front of him. The whole system is designed to be small, light and is used in conjunction with the white cane so that it could ensure safety of the blind.

Efektifitas Pengembangan Alat Bantu Mobilitas bagi Penyandang Tunanetra di Lingkunggan Lahan Basah

“…Penggunaan teknologi Arduino di konstruksi tongkat putih dapat digunakan oleh tunanetra dan membantu mereka mengatasi masalah dalam berpindah tempat (Almousa & Al-Haija, 2018;Orlando, 2019). Sensor dan sistem suara dirancang untuk meningkatkan navigasi bagi para tunanetra (Alam, Rabby & Islam, 2015;Nowshin.,et. al, 2017;Gbenga, Shani, & Adekunle, 2017).…”

An IoT-ML based Proactive Walking aid for the Visually Challenged

“…As per the Table 1, [7] uses a GPS based walking stick that is with medium cost and hence the mass production is not that much feasible because of the latency involved in the system. Some of the works design a mobile app powered stick so that the mobile app controls the stick even through voice commands [8] and [9].…”
