![]() ![]() ![]() If something goes from far away to very close, the differences between left and right can get too big for the brain to put together for the close in images resulting in the fore mentioned headachs, double vision, and motion sickness. Also brightness, contrast, and colors need to be closly matched between the right, and left eye. Avoid too much differences between the Left, and Right eyes. One thing we learned was that you can very easily over do 3D, and make people have headachs and get sick. I got involved with 3D cameras while working with Greaa Valley Group back in 2008 2009. Posted in Virtual Reality Tagged computer vision, virtual reality, webcam motion detector Post navigation ![]() Hopefully, these eye-tracking approaches will continue to evolve and provide improved motion-responsive views into immersive virtual spaces. Generation of view-dependent images based on tracking a viewer’s eye position was inspired by a classic hack from Johnny Lee to create a VR display using a Wiimote. Computer vision algorithms in the library use this geometrical fact to efficiently locate and track human irises with high accuracy. The downside is that the experience only works for one viewer.Įye tracking is performed using Google’s MediaPipe Iris library, which relies on the fact that the iris diameter of the human eye is almost exactly 11.7 mm for most humans. The resulting experience is like a 3D view into a virtual space. The computer screen is made to feel like a window into a realistic 3D virtual space where objects beyond the window appear to have depth and objects before the window appear to project out into the space in front of the screen. The eye position is used to render view-dependent images. The graphical output provides a real sense of depth and three-dimensional space using an optical illusion that reacts to the viewer’s eye position. Spatial Commerce Projects is a Shopify lab working to provide concepts, prototypes, and tools to explore the crossroads of spatial computing and commerce. And Spatial Commerce Projects developed WonkaVision to demonstrate how 3D eye tracking from a single webcam can support rendering a graphical virtual reality (VR) display with realistic depth and space. ![]()
