Computerized planetariums

Bangabandhu Sheikh Mujibur Rahman Planetarium(Est.2003), Dhaka, Bangladesh uses Astrotec perforated aluminum curtain, GSS-Helios Space Simulator, Astrovision-70 and many other special effects projectors [1]

In 1983, Evans & Sutherland installed the first planetarium projector displaying computer graphics (Hansen Planetarium, Salt Lake City, Utah)—the Digistar I projector used a vector graphics system to display starfields as well as line art.
The newest generation of planetariums offer a fully digital projection system, using fulldome video technology. This gives the operator great flexibility in showing not only the modern night sky as visible from Earth, but any other image they wish (including the night sky as visible from points far distant in space and time).

A Sega Homestar home planetarium projector

A new generation of home planetariums was released in Japan by Takayuki Ohira in cooperation with Sega. Ohira is worldwide known as a mastermind for building portable planetariums used at exhibitions and events such as the Aichi World Expo in 2005. Later, the Megastar star projectors released by Takayuki Ohira were installed in several science museums around the world. Meanwhile, Sega Toys continues to produce the Homestar series intended for home use, however by projecting 10,000 stars on the ceiling makes it semi-professional.^[2]
In 2009 Microsoft Research and Go-Dome partnered on the WorldWide Telescope project. The goal of the project is to bring sub-$1000 planetariums to small groups of school children as well as provide technology for large public planetariums
