Engineering Student Develops Smart Goggles for Visually Impaired Swimmers
Pasupuleti Ruthvik is an engineering student who likes swimming.
He made a prototype called Untethered to help visually impaired swimmers know when they are near the end of a pool.
The goggles use sound-based sensors to estimate how far away the wall is.
They then give the swimmer a physical alert, such as a vibration.
Ruthvik began thinking about safety after a friend was injured in an accident.
A programme with mentoring helped him think more about what swimmers need, not just whether he could build the technology.
The project was chosen as one of the Top 20 teams in Samsung Solve for Tomorrow 2026.
The prototype still needs more development and testing in real swimming environments.
Twenty-year-old engineering student Pasupuleti Ruthvik from Chittoor, Andhra Pradesh, developed a prototype called Untethered.
The goggles use ultrasonic sensing to estimate how close a swimmer is to the pool wall.
A haptic alert is designed to warn swimmers as they approach the wall without relying on visual information.
Untethered was selected among the Top 20 teams for Samsung Solve for Tomorrow 2026.
Further development and testing are planned to assess performance in different pools and user comfort.
