Interactive Mirror System
For my Senior Design project my group and I created a Interactive Mirror. You stand in front of a mirror and it will notice you and run some facial recognition. If it recognized you it will pull up your Email, Facebook, Twitter, News, Music, Media, Weather, Health Data among other information. It was voice activated, gesture activated, and could track your hand positions and all of that fun stuff.
