“…We have imported the LiquidCrystal library in our arduino code as it allows an Arduino/Genuino board to control LiquidCrystal displays (LCDs) . In our arduino code, we need to mention which pins are connected with arduino and LCD 16x4 display by using LiquidCrystal lcd (5,6,7,8,9,10).This means 5,6,7,8,9,10 no. pins of Arduino UNO is connected with LCD 16x4 display.So, we can understand the importance the value of LiquidCrystal library over here.…”

From the very beginning of the 20th century, there has been a significant development in the education system using modern technology. However, this rapid development has very little scope to facilitate the education system for the people without sight. Though braille is a method for sight disabled people it has not been incorporated that much with the modern education system. On the other hand, many papers and works have been done on it but a maximum of these is about the conversion of a text character to a braille pattern with considerable accuracy so far no work has been done that can work with voice to convert a character into braille pattern for Bangla language. This paper introduces a development that will help the visually impaired people to start their very basic education with a technology that is capable of recognizing a Bangla character uttered by a person and can convert that character into braille pattern so that using a finger touch one can recognize the corresponding braille for that character. This voice recognition will be done using the Visual Geometry Group (VGG-16) model of Convolutional Neural Network (CNN) and Arduino Uno, LCD 16x4 display will be used to generate the braille pattern for the recognized character. The model is trained with 50 epochs and we achieved 98% of train accuracy and after evaluating test data we gained 92.42% test accuracy.

“…The rapid spread of touchscreens, which do not offer any tactile feedback, amplify this exclusion. To tackle this challenge, there is a crucial need for the expansion of deformable displays, where tactile cuessuch as pinscan appear and disappear. − Beyond the context of visual impairment, sighted users involved in a visual attention task (e.g., driving or piloting) could also use such deformable screens.…”

The development of a cost-efficient braille device is a crucial challenge in haptic technology to improve the integration of visually impaired people. Exclusion of any group threatens the proper functioning of society. Commercially available braille devices still utilize piezoelectric actuators, which are expensive and bulky. The challenge of a more adapted braille device lies in the integration of a high number of actuatorson a millimeter scalein order to independently move a matrix of pins acting as tactile cues. Unfortunately, no actuation strategy has been adapted to tackle this challenge. In this study, we develop a soft actuator based on a thermosensitive poly(N-isopropylacrylamide) (PNIPAM) gel. We introduce macroporosity to the gel (pores of 10 to 100 μm). It overcomes the diffusionwhich is the limiting kinetic factorand accelerates the gel response time from hours for the bulk gel to seconds for the macroporous gel. We study the properties of porous gels with various porosities. We also compare a mechanically reinforced nanocomposite gel (made of PNIPAM and Laponite clay) to a “classic” gel. As a result, we develop a fast-actuating gel with high cyclic performance. We then develop a single-pin braille setup, where actuation is controlled thanks to a swift temperature control of a macroporous gel cylinder. This new strategy offers a very promising actuation technology. It offers a simple and cost-efficient alternative to the current braille devices.

“…A well-known attempt in this field is developing a braille tactile display (Yang et al 2021). Since the current braille systems are bulky and expensive to use, researchers are trying to make the system cost-effective, simple, and accessible (Frediani, Busfield, and Carpi 2018;Zarate et al 2017), (Yobas et al 2003).…”

Haptic interfaces and assistive technologies are improving for visually impaired individuals. In line with these efforts, this paper describes the design, working and implementation of a wearable haptic feedback glove incorporated with a robotic arm to guide the user’s hand in the court. The glove is lightweight, inexpensive and includes coin vibration motors that give vibratory feedback, which describes the direction of the ball. The system was tested on five participants. The participants gave positive feedback regarding the design and the overall experience was good. They recommended the system because it is easy-to-use.
