Right Eye View

View from the right lens of the Virtual Vizor viewer.

This image shows the right eye view of the Virtual Vizor taken with a calibrated camera at a typical eye-to-lens distance (eye relief) of 17 millimeters. The no-parallax point of the camera is set at 20 millimeters (same distance as the eye pupil that is 3 millimeters inside the eye). The image is shown in fish-eye projection to closely simulate what the eye sees. The test image consists of lines that are straight in fish-eye projection such that any distortion can be contributed to the lens of the viewer.

Field of View

Field of view of the Virtual Vizor viewer.

This image shows the field-of-view test from the camera image that is taken at an eye-to-lens distance (eye relief) of 17 millimeters. The IPD (interpupillary distance) was set to 63 millimeters. This is the same as the distance between the optical center of the left and the right lens. The screen size was 5.7 inch. The measured total field of view of Virtual Vizor was 87.2 degrees. The stereoscopic field of view was 84.5 degrees. The field-of-view may differ for other eye-to-lens distances or screen sizes!

NOTE: The field-of-view of non-circular views is calculated as the circular area that is equal to the area that the view covers in fish-eye projection.

Angular Magnification

Angular magnification measurement of the Virtual Vizor viewer.

This chart shows the angular magnification of Virtual Vizor at various viewing angles. The higher the magnification, the shorter the distance between the lens and the screen gets. The shorter the distance of the screen, the bigger the screen will look. The software that renders the environment has to know the exact magnification such that the objects are shown at the correct size. The red dashed line shows the angular magnification of the manufacturer's own QR code.

Distortion

Distortion measurement of the Virtual Vizor viewer.

This chart shows the lens distortion of Virtual Vizor at various eye-to-lens distances (eye relief). The red dashed line shows the distortion correction of the manufacturer's own QR code. The distortion curve is used to produce an image that is distorted in the opposite direction such that the final image that the eye sees looks undistorted.

Chromatic Aberration

Chromatic aberration measurement of the Virtual Vizor viewer.

This chart shows the measured color shift of the lenses of Virtual Vizor.

NOTE: Chromatic aberration correction is done only inside the 'Sites in VR' app! Google Cardboard's VR engine does not support this correction.
