3D Without Glasses or Autostereo
Several companies are developing 3D displays that don't require glasses. This general category of displays are called autostereo or "glasses-free".
Many people are already watching glasses-free 3D on their cellphones and game consoles and other small, single-user screens. The 3D lenses on the screen are calibrated to a ‘sweet-spot’, or a primary viewing position. Many 3D monitors are also autostereo, as the viewer is relatively motionless and a sweet spot can be defined.
Drawbacks exist for moving this technology to the home theater or applying to large-screen TVs. The main drawbacks being cost, viewing angles and sometimes, the need for a differently-formatted content.
There are many products suitable for autostereo displays in commercial and industrial markets where special eyewear is inappropriate. Most experts agree that in 5-10 years we may see an autostereo display offered to consumers for home theatre viewing, but as yet the cost premium is incalculable and picture quality needs substantial improvement.
