Some of you people might remember having see a mouse- a computer mouse in the late 1980's. Then in 2000's we started to move towards touchscreens. Most of them were really awful, until Apple introduced the iPhone in 2007
Now you see touchscreens everywhere, from mobile phones, to the dashboard of your car etc.
The future might me very close that we think- Kinect remember?? maybe we dont even wanna touch the screen!!.(Ya make the humans more less workful- and turn them into people from Wall-E)
