“…In [5], the authors innovated a blind stand that is provided by an Arduino Uno Microcontroller (AUM) and ultrasonic sensors associated with a voice module in order to guide blind people. The authors in [16], [18], and [25][26][27][28][29][30][31] proposed work similar to the work proposed in [5]. In [26], the authors proposed an IoT stick that is able to detect obstacles within 4 meters based on an ultrasonic sensor and a vibrator motor.…”

“…Details about this cost are shown in Table I and Table II. Besides, unlike the previous work ([ [13][14][15][16], [18], [19], [23], and [25][26][27][28][29][30][31]), the proposed IoT system is able to detect obstacles in various directions simultaneously, decide which path (D) a blind person should take, and then guide a blind person to the optimal position using Equations 1 and 2. Furthermore, our work is simpler than the work proposed in [32] since it does not use complicated mathematical equations for calculating the distance between a blind person and an obstacle.…”

Every day, we engage in a variety of activities such as shopping, reading, swimming, and so on. Many people in our community, however, are unable to participate in such activities, due to a variety of eye problems. Directing a blind person to the optimal position (the center of a spot where there is enough space in all directions such that a blind person avoids various obstacles) is a challenge. This paper proposes wireless bracelets that are able to guide a blind person to the optimal position. The proposed system employs ultrasonic sensors in order to detect various obstacles in an indoor environment. It also makes use of the Firebase database and NodeMCU WiFi module to enable realtime communication with a blind individual. Furthermore, the suggested system includes a novel fall-detection mechanism. The proposed Internet of Things (IoT) system is evaluated in an indoor environment. Experiment results showed that the proposed system could efficiently direct a blind person to the optimal position. In comparison to the current state of the art, the proposed system is simpler, less expensive, and more efficient in determining the optimal position to which a blind person must navigate.Index terms-Internet of Things (IoT) bracelets, IoT navigation system, visually impaired, real-time communications, NodeMCU, Firebase database.

“…If any obstacle comes in front of blind person, he/she can know about the obstacle by hearing the sound generated by the BUZZER. N.Loganathan,K.Lakshmi,N.Chandrasekaran, S.R.Cibisakaravarthi, R.Hari Priyanga, K.HarshaVarthini (2020) [6] proposed a blind stick using Arduino Uno with the help of an ultrasonic sensor and infrared sensor which detects the distance between object and the person.…”

An visually handicapped person finds it tough to find the presence of any obstacles in their approach and it's terribly tough to search out the precise location of the stick if it is misplaced. Thus, the multifunctional blind stick comes as a projected answer to assist the visually impaired folks in their day to day living while not the assistance of others. This paper conducts a survey on few of the vital and up to date developments in blind sticks keep on with the utilization of various microcontrollers, sensors, and technologies. Keywords—ultrasonic sensor, radio frequency transmitter and receiver, obstacle detection, controller, GSM and GPS.

“…Meanwhile, there are not many visual aids that can be used directly without involving medical action at all [7]. In other words, there must be an assistive device that people with disabilities need to wear and be given a brief lesson on how to operate the tool, and then the viewing aid is ready to use [6,8,9]. In avoiding objects when navigating in a specific environment, the problem is how an aid device can accurately measure a distance [10,7,11].…”

A Novel Algorithm of Distance Calculation Based-on Grid-Edge-Depth-Map and Gyroscope for Visually-Impaired

This paper presented a new algorithm for determining the distance of an object in front of a stereo camera placed on a helmet. By using a stereo camera with a Sum of Absolute Difference with a Sobel edge detector, our previous Grid-Edge-Depth map algorithm could calculate the objects’ distance up to 500 cm. The problem started when a vision disability person used the device with an unfixed stereo camera angle. The unspecified angle caused by the helmet’s movement influenced the distance calculation result. This novel process started with calculating the distance from a Grid-Edge-Depth map considering unfixed angle data of the x-axis from a gyroscope sensor placed on the stereo camera using the trigonometry formula. The angle data used was the x-axis data. The distance measurement results by the system were then computed based on the unfixed angle compared to the actual distance. The test was carried out with three scenarios which required the user to stand at a distance of 100 cm, 125 cm, and 150 cm from a table, chair, or wall, with 30 tests for each scenario. The test results showed an average accuracy of 96.05% with three experimental scenarios, which meant that this machine was feasible to implement.
