Accurate Eye Imitation for VR HMD Testing

When it comes to VR/AR HMD objective testing, you need an “eye” which is much more than simply a digital camera. Besides having the entrance pupil, focal length and aperture similar to those of a human eye to see like a human eye, the imitation must be properly perceived by the eye tracking modules.

Meet the First in the World accurate eye imitation created by Almalence.

Not only sees like an eye, but also looks like an eye

Using a special compound developed at Almalence lab, we managed to create an imitation of the iris that looks correctly in both visible and infrared light, which makes the eye imitation correctly detected by eye tracking devices. To make the imitation totally indistinguishable from an eye of a human being, the imitation is made to give proper reflections and glint locations.

Whist having all the above properties, the imitation has a cover glass made of an optical-quality transparent material, which does not distort the light passing to the camera. The camera, in its turn, has the entrance pupil properly positioned within the “eye” using special micro-mount.

With the above features together, we have achieved a perfect “two-way immersion” — the eye imitation not only sees exactly what a human eye would see, it also looks exactly as a human eye to the eye tracker.

The eye imitation will be used for better optical profiling of VR HMDs to achieve the highest possible quality with Almalence Digital Lens technology and for accurate objective testing of VR/AR HMD picture quality.
