Design And Implementation Of Object Sensors On Assistive Devices For The Visually Impaired

Abstract

Blind is a general term used for the condition of someone who experiences problems or obstacles in their vision. Assistive tools for the blind using stainless steel sticks or using paralon sticks that are designed to be sticks, which are white with a sensor in the middle (Dedy irawanRio & Wulansari, 2021). As a result of the loss or reduction in the function of their sense of sight, blind people try to maximize the function of their other senses such as touch, smell, hearing, and so on, sometimes they also find it difficult to find their way from one place to another using the traditional cane ( Muhammad, 2018). The cane functions as a guide and to make daily activities easier and also as a cane as a substitute for eyes for the blind (Dedy irawanRio & Wulansari, 2021). But the stick also still has weaknesses inside. Traditional sticks also make it difficult to recognize an object in front of us. what the blind often use is to use estimates when entering a rising road. To make this tool, software and hardware are needed. Where to control the hardware, a microcontroller is needed, namely an electronic component that can work according to a program that is loaded into its memory, like a very simple computer (Tarigan et al., 2020). Microcontrollers are very suitable for use with specific purposes because their large ROM and RAM ratio means that the control program is stored in ROM which is relatively larger in size, while RAM is used as a temporary storage area, including the registers used in the microcontroller in question. Based on this and developing previous research, the author conducted research with the title "Design and Implementation of Object Sensors in Assistive Devices for the Blind." In this research the author proposes a tool or system that is capable of detecting obstacles in assistive devices for the blind, which is very important for notifying them of their existence. objects or obstacles for blind people when walking
