While we saw a number of notebooks featuring Nvidia's 3DVision technology in 2010, 2011 was the year 3D dropped the glasses and came to handsets. At CES 2011, Toshiba showed off a glasses-free notebook that tracks users' eye movements in order to provide three-dimensional images without the need for glasses. This product later hit the market as the Toshiba Qosmio F775, which provided sharp but shallow 3D effects that couldn't match up to those on regular active-shutter 3D notebooks such as the Toshiba Qosmio X775.
At Mobile World Congress in Feburary, LG showed off the first stereoscopic 3D phone. Since then, both LG and HTC have hit the market with 3D handsets in the HTC EVO 3D and the LG Thrill 4G. LG also released the T-Mobile G-Slate that had dual cameras for shooting photos and videos in 3D, though you needed glasses to see the extra dimension.
