This invention describes a device for teaching phonics using physical tiles. Each tile has a letter or letter combination and a surface you can touch. These tiles are placed onto an electronic board, which identifies them and sends this information to a speaker or screen to help teach sounds. The claims specify that the tiles must also have raised, feelable shapes like letters or lines.
Why it matters: Since 2018, the cost of embedded electronics and sensors for detecting physical objects has significantly decreased. This makes manufacturing the interactive interface and custom tiles more economically viable for a consumer product.
