TDVision

TDVision was founded in 2001 by Manuel R. Gutierrez Novelo in Mexico and was moved to the US in 2004. The company found problems with current 3D display technologies, such as the lack of compatibility with 2D existing pipelines, side effects due to visual artifacts and eye strain. The company designed a stereoscopic system that emulated human vision to reduce some of these side effects. This included a new codec called TDVCodec that was designed to work with current hardware, such as DVDs, set top boxes and satellite receivers.

Applications
TDVision is being adopted by several military, aerospace and medical institutions because its backward compatability, human-eye emulation, portability and high definition rates.

Comparison to other stereo related technologies
Autostereoscopy, LCD_shutter_glasses, polarization, Circular_polarization, field sequential, 3D vertical interlaced, 3D horizontal (pixel) interlaced and Holography are based on optical methods to trick the eye or split an image into Left and Right. This is not natural to the human eye since humans perceive constant, uninterrupted images. When the brain perceives flickering, overlap, dramatic color polarizations or visual artifacts this can cause side effects including headaches, eye strain, and dizziness. The company's technology provides the user with 3D continuous videostreams at high resolution and provides a large equivalent screen size allowing the user to perceive the information as real images. The brain does not perceives any difference with respect to real life and does not presents any side effect allowing long periods of usage.
