A patent application filed by Nokia shows a dual-screen device capable of rendering 3D objects.
Autostereoscopic Rendering and Display ApparatusNokia may be working on several additional products for Microsoft outside Windows Phone 7, one being a dual-screen device capable of rendering 3D images and a Windows 8 tablet. Both devices are unconfirmed, but the dual-screen device has actually shown up in a patent application called "Autostereoscopic Rendering and Display Apparatus" published on April 21.
According to the filing, the apparatus comprises of a sensor configured to detect the position and orientation of a user viewpoint with respect to an auto-stereoscopic display. There's also a processor configured to determine a surface viewable from the user viewpoint of at least one 3D object, and an image generator configured to create a left and right eye image "for display on the auto-stereoscopic display dependent on the surface viewable from the user viewpoint."
Based on the image, it appears that one screen will render the 3D image and the other screen will render 2D imagery like shadows and reflections which changes as the eye level changes. There's no indication that the user will need special glasses for this holographic effect to work-- we're betting Nokia is planning to use the same tech found on Nintendo's new 3DS platform (or a better version).
As for the Windows 8 tablet, that should be expected given Nokia's recent marriage with Microsoft. The news arrives as a mere rumor from Eldar Murtazin who claims that Nokia is churning out at least one Windows 8 tablet slated for 2012 or 2013 at the latest. There's also talk that Nokia will still release Symbian-based devices in 2012 while creating Windows Phone 7 phones for Microsoft, possibly between five to seven mid-to-high end devices. Maemo 6 is a "dead horse," with only 92000 units produced.
Nokia is reportedly aiming for 21-percent of the smartphone market share worldwide in 2011, and 27-percent of the mobile phone market overall.
