TT-ARVR: Software Module for AR/VR Display Testing

01 Jan 2019

Displays viewed near to the eye create immersive virtual experiences, such as those integrated into AR/VR devices. However, as display images are magnified to fill a user’s field of view (FOV), display defects are also magnified. Issues with uniformity of brightness and color, dead pixels, line defects, cloudiness, and image position become more evident to the user whose eyes are merely centimeters away from display screens.

Part of the Radiant Vision Systems TrueTest™ Software family, the TT-ARVR module provides all of the benefits of TrueTest Software to efficiently perform light, color, and dimensional measurements with specific tests to evaluate the quality of displays integrated into AR, VR, and MR (mixed reality) devices and headsets. A comprehensive AR/VR display test solution from Radiant combines the TT-ARVR application-specific software module, a ProMetric® Imaging Colorimeter or Photometer, and the Radiant AR/VR lens to perform rapid, automated visual inspection of AR/VR displays.

TT-ARVR uses a ProMetric imager to test all display characteristics simultaneously, capturing and processing data much faster and more consistently than a human inspector or a spot measurement device.

Comprehensive Display Test Suite

Tests for near-eye display (NED) quality include photometric measurements used to evaluate an imaged display’s light and color properties for defects and accuracy against defined tolerances. TT-ARVR allows users to define a complete set of measurement parameters and pass/fail criteria for specific points of interest on a display. The software module includes standard display tests, as well as specific tests for AR/VR quality including:
