Autostereoscopic 3D: No Glasses but still 3D

In the business people are often talking about stereoscopic and autostereoscopic but what do they mean?
Stereoscopic is a 3D picture or movie that has two points of view. You see them in stereo giving you the 3D effect. When you put on the glasses, they filter the images so each eye only sees one picture. That allows you to see 3D. This is often used for 3D movies and 3D computer games, but can also be applied to many professional areas like design, medical/bio, GIS and product presentation. Now you can work with 3D on the job and then go home and watch it on your 3D TV or 3D monitor.
As for Autostereoscopic, it is similar to stereoscopic 3D but you can see the 3D effect without wearing the glasses. With this kind of 3D, there may be two points of view or multiple points of view. There are different ways of making these displays such as the parallax barrier and lenticular lenses.
