Student Team:
Q. What inspired you to create Communica? What roles did each member play in the project?
A. The Capstone Project is a 10-month initiative where all grade 10 students work in teams of five to identify and solve community problems using technology. The inspiration for our project, Communica, came when one of our team members visited a petrol pump and encountered a hearing-impaired employee struggling to communicate. This experience deeply moved us, and we decided to address this issue.
Our team consists of four members: Aaditya Seth, the Project Executive and Programmer; Samaira Taneja, the Web Developer who also completed a certified course in Indian Sign Language to interact deeply with the hearing and speech-impaired community; Armaan Srivatsan, the Content Writer and Editor; and Sehraj Kapoor, the Product Developer and Financial Advisor.
Q. Please walk us through the steps you took from ideation to implementation of the project? What were some of the biggest challenges you faced and how did you overcome them?
A. Our team began ideating after discussing an experience shared by one of our members. To better understand our target audience and the challenges faced by the hearing and speech-impaired community, we decided to engage directly with them. We visited a petrol pump and spoke with the hearing-impaired employees and the manager to gain insights into their daily tasks and communication difficulties.
The manager explained the problems the employees faced, highlighting that the only means of communication with them was through written text due to his lack of sign language skills. These interactions inspired us to create an intelligent glove designed to help these employees communicate with customers in a more inclusive manner.
We began developing the glove's design and visited the petrol pump regularly to get feedback from the employees. One significant challenge we encountered was the variation in hand movements, which caused different readings for the same gesture on different hands. To address this, we rigorously tested the glove on many people to obtain average values for each gesture, ensuring accuracy and reliability.
Through continuous iteration and feedback, we aimed to refine the glove to meet the needs of the hearing-impaired employees effectively. This process underscored the importance of direct engagement with the community to create a practical and impactful solution.
Q. Can you explain how the smart glove works? What technologies and tools did you use?
A. The Communica gloves primarily consist of a Flex Sensor, MPU6050 (gyro sensor), speaker, haptic feedback motor, web app, and ESP32 (MCU). Here’s how they work:
Deaf users wear the gloves and make custom gestures. Each gesture produces outputs from the flex sensor (measuring the bend of each finger) and the gyro sensor (capturing hand orientation). Multiple readings from these sensors are averaged to predict different gestures and train a Machine Learning Model.
The ESP32 is configured as an asynchronous web server and serves as the main control system, connecting the flex and gyro sensors. TensorFlow Lite is used to train the ML model for the edge computing device, which is then deployed on the ESP32. After deployment, the ESP32 tests the gloves by asking the deaf person to make gestures similar to those recorded, ensuring accurate predictions.
A user-friendly web app connects to the ESP32, allowing the user to visualise in real-time how much each finger is bent. Once a gesture is recognised, the ESP32 speaks the corresponding sentence or word and provides haptic feedback to the user, indicating that a word has been spoken.
For the final prototype, three different gloves were designed and tested with various MCUs (Arduino Nano, Arduino Lilypad, and Arduino Uno) with different deaf individuals. The ESP32 was found to be the best fit for the requirements, so the final prototype was designed using it.
The Communica glove is rechargeable, lasting up to 6 hours on a single charge, and includes a battery charge indicator.
Q. How did you ensure the accuracy and reliability of the sign language translation?
A. The accuracy and reliability of the Communica glove is ensured through extensive testing with the target audience and continuous improvements based on their feedback. Unlike traditional sign language translators, Communica does not convert standard sign language gestures. Instead, it creates a customised repository of gestures tailored to the user's work profile and specific needs.
Q. Have you received any feedback from the hearing-impaired community? If so, what has been their response?
A. We tested our project with several hearing-impaired employees at a Bharat Petroleum station. The gloves significantly assisted them in communicating with customers during their shifts. They provided valuable feedback on various aspects, such as comfort and battery life, which we used to improve the glove's design. According to their feedback, if our project is developed into a full-fledged product with mass production, it could greatly enhance the social and work lives of hearing-challenged individuals.
Q. Can you discuss the real-world application and potential impact of Communica beyond the school environment? What are the possibilities of introducing the device for broader use in the future?
A. Communica has significant real-world applications and the potential to create a substantial impact beyond the school environment. By facilitating effective communication for deaf individuals, the glove can enhance their ability to interact with others in various settings, such as workplaces, public services, and social environments.
The possibility of introducing Communica on a larger scale is promising. Mass production and distribution of the glove could make it accessible to a wider audience, significantly improving the social and work lives of hearing-impaired individuals. This could lead to more inclusive workplaces and public spaces where communication barriers are minimised.
Furthermore, the adaptability of Communica allows it to be customised for different work profiles and personal needs, making it a versatile tool for various industries. By continuing to refine the technology and gather feedback from users, we can ensure that Communica remains a reliable and effective solution for enhancing communication for the deaf community.
Overall, the broader implementation of Communica holds the potential to foster greater inclusivity and accessibility, making a positive difference in the daily lives of individuals who are hard of hearing.
Student Mentors:
Q. How did you guide and support the students throughout the development of Communica? What teaching or mentoring strategies did you find most effective in helping the students achieve their goals?
A. Capstone is a student-led project where students identify a problem, and we, as mentors, guide them through each step of the process. Our role as facilitators is to provide direction and support by brainstorming challenges and solutions together at each phase of the project, from ideation to prototyping, testing, and implementation. We also help them develop strategies to approach their problem, plan their project timeline, allocate resources effectively, and iterate on their designs based on feedback.
