It’s important to teach children to differentiate good words from bad words at early age, this is where GUARDPIX language device comes in handy. Designed by Seo Donguk, this portable device can help you as parent to form desirable language habits of your children, especially when they are at the age of 2 to 3-year old. Because at this age, children have started to make friends and become chatty, it would be very easy for them to imitate adult conversation. GUARDPIX lets children know when someone says bad words by displaying unique facial expression just like emoticons. Too bad this device is just concept.
