Rehan Khan outlines his project’s goals and the broader vision that he hopes to address through this innovation
Rehan Hyder Khan from Airway Public School, Vasco has secured a patent from the Central Government of India for his invention of a navigation stick which helps the visually impaired.
He feels privileged and honoured to have received a design patent for his project and expresses a deep sense of being blessed and finds himself motivated to contribute towards the betterment of society. His aim is to make his navigation stick readily available in the market at an affordable price, ensuring that even the poor and needy can benefit. The device is also designed to make life easier for elderly individuals.
Rehan’s inspiration comes from the legendary Dr A.P.J Abdul Kalam, Nikola Tesla, and his father, Hyder Khan. The idea for his project came to him when he witnessed his cousin, who is visually challenged, struggling with many daily tasks. This experience sparked the concept for the project.
“At Airway Public School, we are proud to nurture future scientists, engineers, and innovators. Through our commitment to science and robotics, we ensure that our students are ready to lead in a tech-driven world,” says Karun Cherian, Manager, Airway Public School
The project, which involves the development of a device for blind individuals, stands as a testament to the potential of powerful technology. It integrates various elements and technologies into a single device designed to improve the safety, autonomy, and social interaction of the visually challenged.
Goal of the Project
The primary objective of Rehan’s project is to address the challenges that the visually challenged face in their daily lives. Traditional walking canes offer limited assistance to the blind, relying on outdated methods. His device aims to integrate navigation technology, health monitoring systems, and connectivity features to enhance safety and empower users with greater independence. 
Devices of the Project
Several devices are part of this project, including:
Ultrasonic Sensor: This device warns the user of barriers through a buzzer, acting as the first line of defence by avoiding threats during navigation.
GSM Module: This feature enables communication, allowing the device to send text messages or make phone calls, especially useful in emergencies.
Mini Screen: A display that provides essential information, such as alerts for calls and messages, and shows the device’s current state.
Button: Allows the user to press a button to instantly call a guardian or send a preset message.
Drone (in development): Currently in the design phase, the drone will help locate the user, provide real-time footage to the guardian, and assist with navigation. When the drone hovers above the stick, it will change colors and project a laser on the stick to indicate its position. This feature will require more expertise and time to develop fully.
Heart Monitoring System (in development): This system is being designed to monitor the user’s pulse and blood pressure, sending alerts to the guardian if abnormal readings are detected.
Chatbot (in development): A built-in assistant that will provide auditory alerts, such as notifying the user about the time or warning them when nighttime approaches. This feature is still under progress.
Impact of the Project
This device aims to significantly improve the quality of life for the visually challenged.. By addressing challenges such as navigation, health monitoring, and communication, it provides a comprehensive solution to their daily struggles. The ultrasonic sensor ensures safe mobility, while the GSM module enhances connectivity with caregivers. The proposed heart-monitoring system will offer peace of mind by passively tracking the user’s health.
The integration of advanced technology, such as the drone and chatbot, highlights the project’s innovative approach to solving real-world problems. The drone will bridge the gap between users and their guardians, enabling real-time communication and visual monitoring. The chatbot will provide continuous assistance, ensuring the user feels supported at all times.
Rehan’s project represents a significant step toward empowering the visually challenged through technology. By combining practicality and innovation, it addresses critical issues of safety, health, and communication. Although some features, such as the drone, heart-monitoring system, and chatbot, are still under development, they demonstrate the potential for future expansion.
This device not only improves the lives of its users but also showcases how technology can promote greater inclusion and support in society. Rehan says, “I am committed to further developing this project to create a meaningful impact on the lives of those in need.”
