The project consists of an application on geometry that can be "shared" by any person, whether or not visual impairment and / or low vision.
This is a set of exercises created with Scratch, with the help of card / RF chips built-in physical pieces - to interact by touch and sound with your computer.
Cards / chips RFID (Radio Frequency Identification), can replace the mouse and even keyboard.

This project was awarded first prize in the category "Science, Technology and Values" at the last congress "Science in Action" held at CosmoCaixa Alcobendas (Madrid) in October 2012
