Microsoft

Recently Microsoft published details of a patent involving a light-induced shaped-memory polymer display screen.  It is essentially a touch screen that has a real texture and has tactile feedback, making it feel like users are actually touching an object.  It was invented by Erez Kikin-Gi.  This screen is coated with polymers that could change or hold the shape when different wavelengths of ultraviolet light hits the pixels from bbeneath it.  This sort of technology is interesting because it goes more in depth into making a user feel as if what they are controlling on the screen is real, because it could not only just display images but also specific interfaces such as a keyboard making the sure feel like they are actual typing onto one.  Unfortunately for now this technology will only initially find it's way onto large screens like Microsoft's Surface computers.  It will certainly be a technology many people will find interesting in the future.
