Oded Ben Dov originally made an eye tracking video game, meaning you can move things with just your eyes. A day after showing his video game, he was contacted to make a smart phone for disabled people so they too can have all the same resources. This is a huge advancement in technology and gives many people who are disabled many more opportunities. This is still in the works but many companies like YAHOO, Apple, and Android are helping to make this technology available for everyone.
