If you want to know what computing will look like in the near future all you need to do is watch this video from TED. It showcases Sixth-Sense technology.
Once this technology matures I believe we will interact with it through a pair of contact lense and an extremely small hearing aid. This device will allow us to get all sorts of meta data about our surroundings and probably completely replace all of our traditional ways of interacting with computers.
As we drive the road in front of us will literally light up in front of us, showing us how to get where we are going. We will also always be aware of the speed limit and have access any other information about the roads. For example, we may know that a deaf child lives up ahead, or there is a better way to our destination based on the traffic situation in the present city.
While walking a nature trail we can get information about any relevant historical information, such as perhaps a famous explorer walked it hundreds of years ago, or find out about the plants and animals we see. We could see which plants are edible and which are poisonous. If we catch a fish we could immediately know if it is of legal size to keep.
When meeting people we could look up their profile on the currently popular social networks through facial recognition. We could then know that they are interested in certain topics you are also interested in and strike up a conversation. Or you could meet someone at a bar and find out that they are a known sleaze bag, and then take them home.
The possibilities are endless, and the benefits can be enormous.
