Yes, it is a prototype. The phone by Matthias Pinkert is designed to be foolproof phone. The phone just only has 4 keys! One for direct calling, one for one-touch calling, one for GPS tracking, and the other for speaker phone.
Who is suitable using this phone? Of course our granny. They didn't need to see all those buttons lie around. Click here and there, voila! The granny can phone her grandchildren.
