The Future of Display Technology

We have eye tracking technology that can detect what the user is looking at. And then when combined with those 3D sensors that are looking outward, it may be able to see me pick up this mug of coffee and combine the weight visual data from the coffee mug with the expression on my face. It could tell that I want some more coffee and then it could order more coffee for me from Amazon or perhaps it could brew me another cup of coffee. Yeah, life is starting to get really easy.
