Abstract

Smart cane with location detection using RF module

Highlights

The basic research to do the study about the aid tools to enhance the ordinary cane such as a navigation module to avoid the obstacle and inform the blind with voice announcement has already doing for indoor area (Thumma et al, 2017)
The guidance of a wearable indoor navigation system for blind and visually impaired has been done with integrated system between audio module, wireless communication module, sensor module, database module and path finding subsystem and signal processing (Bai, 2014)
RF-based location awareness for blind sends the communication using NRF24L01 module by sending the data signal from the transmitter in a building and received by the receiver in the smart cane. This module communication NRF24L01 should be better implemented in the outdoor area, whereas this module can reach distance range around 40 m away from the transmitter while this module can reach only 7 meter away from transmitter if implemented in indoor area

Summary

Introduction

The basic research to do the study about the aid tools to enhance the ordinary cane such as a navigation module to avoid the obstacle and inform the blind with voice announcement has already doing for indoor area (Thumma et al, 2017). The blind can recognize the place and guidance to the destination area (Khine et al, 2014). Some research proposed the study to build an outdoor navigation system to assist Visually Impaired person’s navigation independently in urban areas, regardless of the person’s hearing status (Chaudary and Pulli, 2014). They used an augmented cane magnetic point and serialized vibration braille to encode guidance system. This research, proposed a prototype that can embed in a cane to enhance the functional of a cane as location awareness, which can help the blind to configure the building destination. This system will be tested and implemented in certain building in Telkom University building area
