Information technologies have become necessary in the area of the health sector, with the new trends that are emerging, this work aims to develop a prototype of a smart cane to improve travel, allowing to avoid obstacles that obstruct the path of visually impaired people. The methodology used was traditional through the stages of analysis, planning, design, development, testing and implementation, for the development of this prototype the Arduino IDE software was used, using as controller an ARDUINO ONE, for the control of distances, it was used HC-04 ultrasonic sensors, transmitting signals through the vibrating motor and a buzzer that emits a different sound depending on the programming of the ultrasonic sensors. All these connections were linked to an experimental table called Protoboard, which are directed to the ARDUINO ONE board. The final product allowed to have a cane that was tested with, people with visual weakness, the functionality was measured with a questionnaire that evaluated the mobility function and the results were greater than 80% of acceptance

It is increasingly common for engineering degrees to include the teaching of programming in their curricula. The present work focuses on the teaching of basic Arduino IDE programming and implementation of an Arduino Uno board. The teaching of Arduino IDE programming is basic and can be applied to related careers such as Information Technology and Mechatronics. It is an appropriate model so that the students of these careers are motivated to visualize in concrete form the results of the programs developed by them. An Arduino Uno board was introduced as the main element, based on hardware and software principles for the implementation of programming practices whose inputs and outputs are HC-04 ultrasonic sensors and other components such as Buzzer and Micromotor. This work is based on the planning of a smart cane prototype that helps visually impaired people. These learnings acquired on basic programming in Arduino IDE, can be implemented in different projects where Arduino Uno is used

Visually impaired people are faced with challenges in detecting information about terrain. This paper presents a new walking support system for the blind to navigate without any assistance from others or using a guide cane. In this research, a belt, wearable around the waist, is equipped with four ultrasonic sensors and one sharp infrared sensor. Based on mathematical models, the specifications of the ultrasonic sensors are selected to identify optimum orientation of the sensors for detecting stairs and holes. These sensors are connected to a microcontroller and laptop for analyzing terrain. An algorithm capable of classifying various types of obstacles is developed. After successful tests using laptop, the microcontroller is used for the walking system, named ‘Belt for Blind’, to navigate their environment. The unit is also equipped with a servo motor and a buzzer to generate outputs that inform the user about the type of obstacle ahead. The device is light, cheap, and consumes less energy. However, this device is limited to standard pace of mobility and cannot differentiate between animate and inanimate obstacles. Further research is recommended to overcome these deficiencies to improve mobility of blind people.

<p>The joy we derive from our ability to commute and interact freely with the world as a result of our possession of sight with the naked eyes are enormous however the Visually impaired people find great difficulty in moving around freely without a human guide, especially in a new terrain. This research reports the design and fabrication process of an intelligent walking staff (iWalk) specially designed for the visually disabled individuals to argument their loss of sight, improve and ease their navigation. iWalk was designed around water and ultrasonic sensors to detect obstacles and water ahead. iWalk also has a wireless RF remote control buzzer for localization and detection in case it gets misplaced. The proposed system operability and efficiency was adequately tested using physical dataset composed of randomized locations with random obstacles and water. The proposed algorithm achieves an overall efficiency of 90% detection rate for water and ultrasonic sensor and 85.75% for the RF wireless remote control.</p>
