Stereoscopic Distortion

A stereoscopic distortion occurs when the optics of a stereoscopic display device and the eyes of a user do not mesh perfectly. One or more of the optics is out of alignment with the eyes, and the images are not processed in fusion (combined to form one image in the brain). Instead, there is a distortion effect caused due to the misalignment.

This distortion is often very hard to spot. It is typically easy to tell that something is wrong, but hard to put your finger on exactly what. If it is not corrected, the end result is strain on the eyes due to the unnatural focussing angles, and ultimately headaches and nausea.

Stereoscopic Display Methods
Visual stereoscopy comes in many flavours. Depending on how the video feed is constructed, and whether or not it was originally designed with stereoscopy in mind, the technology used to deliver a slightly different positional viewpoint to the eye, differs greatly.

PET Resolution Increases by Leaps and Bounds
ET scans suffer quite a bit when they image moving tissue, such as a beating heart. No scan is instantaneous, and as the slices move down, the beating of the heart causes distortion that is hard to remove from the result, as pieces do not line up correctly. A solution to this, that increases the resolution as a side-effect, may have been found.

Fast Adaptive Optics for 3D Medical Imaging
One of the greatest problems with tomography based medical scanners, is what happens when the patient moves (breathes, or pumps blood). The distortion that occurs in each slice has long been correctable, but takes a long time to correct. With near-instant correction now possible, real-time medical scanning is starting to look like a true possibility.

Stereoscopic Broadcasting Begins
With the hubbub surrounding cinema 3.0, and 3D stereoscopy in the cinemas, it seemed only a matter of time before stereoscopy as the next great buzzword of the passive entertainment industry (broadcast networks) started to filter into broadcasting.

Combating Noise and Distortion When Linking Aircraft to the wider Sensor Net
Commercial aircraft are a problem when it comes to linking them to the wider sensor net - all external electronic communication flows through a single part of the nose of the plane. This must be precision manufactured to be defect-free, or moisture and heat can tear the signal apart. How then, do you guarantee it is defect-free?

Artists 'draw on air' to create 3D illustrations
Slipping an slim line, lightweight stereoscopic HMD over your eyes; each of the two screens sending data to a different eye, giving the same angles in the virtual world as light takes to each eye in the physical. Holding a stylus in one hand, and a 3D pointer in the other. This is the set up for art work, heavy engineering design or model making with ?Drawing on Air?.
