Three Students Built a Device That Lets Visually Impaired Children Learn Coding Through Touch
Three students in Greater Noida built TACTO — a device that teaches coding through touch, sensors, and audio feedback, no screen needed. It just won top honours at a global competition in Hong Kong, beating 19 teams from 10 countries.
For most people learning to code today, the starting point is a screen. A cursor blinks, blocks of colour shift, and feedback arrives visually, instantly.
