Three students from the Department of Computer Engineering at the Kwame Nkrumah University of Science and Technology (KNUST) have developed an innovative smart tool designed to assist people who are visually impaired.

The device, known as the Smart Visually Impaired Kit, is integrated into a necktie and allows users to "see" their surroundings with the help of a miniature camera and a mobile app.

The student team: Kelvin Yirenkyi Ofosu, Nathaniel Kwarko Marfo, and Victus Agbakpe Etornam,is working under the supervision of Dr. Henry Nunoo-Mensah.

The students were inspired to create the device after learning about the daily challenges faced by visually impaired individuals. While tools like walking sticks and guide dogs provide support, they do not address all the difficulties these individuals encounter. The team set out to build something new that could offer greater independence.

The Smart Visually Impaired Kit uses a discreet camera embedded in the necktie to capture images of the user's surroundings. These images are sent to a mobile app, which processes them to help the user understand what is around them. The app also offers navigation support, helping users move safely and confidently.

What sets this kit apart is its discreet and wearable design. Unlike smart glasses or assistive canes, the necktie blends into everyday attire, allowing users to keep their hands free while navigating.

The team plans to conduct further testing and enhance the mobile app’s functionality. They also hope to collaborate with health professionals and organizations that support people with visual impairments, to improve the kit and make it more widely accessible.

This innovation will be one of many featured during Technology Week (Tweek) 2025, a celebration of how young innovators are using technology to solve real-world problems and improve lives.
