Architecture of IoT based blind's person stick 4. SENSOR DATA IN GRAPH Ultrasonic sensor provides 2cm-4m non traffic measurement criteria. This module has four part VCC, GND, Trig and Echo. This module measures distance by performing math operation based on Sound echo. Measuring distance equation is given below: Test distance = (T× V) / 2 Where, T = High level time V = Velocity of the sound Using this mathematical equation we present the graphical representation of data. Fig 4. Shows the graphical data of ultrasonic sensor.

Visually impaired people are facing difficulties during day-to-day activities in terms of traveling and receiving accurate information from their surroundings. Most of the time, visually impaired persons need to rely on others. Blind people cannot walk without the support of a cane. Artificial intelligence of things (AIoT) is the solution to design...

The inability to see makes moving around very difficult for visually impaired persons. Due to their limited movement, they also struggle to protect themselves against moving and non-moving objects. Given the substantial rise in the population of those with vision impairments in recent years, there has been an increasing amount of research devoted to the development of assistive technologies. This review paper highlights the state-of-the-art assistive technology, tools, and systems for improving the daily lives of visually impaired people. Multi-modal mobility assistance solutions are also evaluated for both indoor and outdoor environments. Lastly, an analysis of several approaches is also provided, along with recommendations for the future.
... Figure 4 shows structural development of blind stick. Here, we have placed three ultrasonic sensors in front, right and left direction [16][17][18]. An ultrasonic sensor measures distance within 3 m by using sound reflection methodology and echoes. ...
Bengali is the seventh most spoken language, and 300 million people around the world speak in Bengali. The smart home is responsible for the digitization of modern society. This research reflects an Internet of Things (IoT) based smart solution, especially for the people who have a visual impairment along with the smart home. The proposed methodology presents a developed android application which will act as a smart assistant. The smart assistant is responsible for communicating with a blind person, browsing thoughts, and sharing ideas using the Bengali language. The proposed solution also focuses on the embodiment of IoT based blind stick. This article further assures a structural foundation of a smart home where blind persons and regular users will be able to control all the home appliances using Bengali voice command. This paper also illustrates experimental data analysis, such as transmission time calculation for GSM/GPRS and Bluetooth module, empirical coverage area calculation, a system usability scale (SUS), and data analysis of blind stick. We have found a SUS score of 84%. However, the proposed system will be beneficial and handy.
The new coronavirus, which produces a highly contagious sickness, enters the picture. Globally, the coronavirus disease (COVID-19) has boosted the use of Internet commerce. It has resulted in an increase in the number of FTUs, or first-time e-commerce users, in India, who were previously unable to purchase online. Customers are depending on Amazon more than ever before in their social isolation and self-quarantine attempts, according to Amazon, one of the country’s and the world’s major e-commerce businesses (https://retail.economictimes.indiatimes.com/re-tales/impact-of-covid-19-on-onlineshopping-in-india/4115). The goal of this study is to determine the elements that influence customers’ online purchases of mobile phones, as well as how that practice has altered since the global COVID-19 outbreak. An online survey was done, and data were gathered from primary sources to interpret the objectives. The goal of the study is to figure out how successful online advertising is at raising awareness and what the link is between Internet advertising and purchasing decisions.KeywordsCovid-19E-commerceMarketingConsumer choiceInternet advertising
The Internet of Things (IoT)-based third eye glove is the solution for the blind and employs ultrasonic sensors and an Arduino UNO board. The goal of the IoT is to link physical items, such as computers, to other physical objects, such as other people. Currently, it is a market-enabling technology that is quickly evolving and increasing. As many as 1.6 million youngsters are amongst India’s 40 million blind people. Blind people have a tough time travelling on their own. They have to rely on others in many aspects of their existence. When they’re strolling along the street, this is the biggest problem. With a stick in hand, they will not be able to see every obstruction. One may wear this sophisticated glove design for a long time. The third eye glove will assist the blind individual in achieving their goal. Sensors, microcontrollers, and buzzers are all integrated into the glove’s design, which is IoT. The sneaker emits a buzzing sound as the user approaches an obstruction. Smart gloves, which have sensors and can cover a larger area, are being developed to increase productivity. Smart health monitoring and smart gloves ensure that the user does not have any problems.KeywordsBlind and deafIoTSensorGlove
