Automated Vision Tester

Despite recent tremendous leaps in the development of new technologies for image recording, presentation, manipulation, 3D capabilities, and analysis, many vision exams are still performed using paper Snellen charts, paper color charts and Amsler grids. Current procedures are time consuming, labor intensive, potentially subject to transcription errors and test preparation, which may compromise the test integrity. Therefore, DHP seeks the development of threshold-based tests supporting vision screening relevant to most current military aircrew standards. This includes, at minimum, acuity, color, ocular motility (hyper/hypo/eso/exo phoria/tropia), and stereo. To address this DHP need, Hedgefog Research Inc. (HFR) proposes to continue the development of the Automated Vision Tester (AVT) system with adaptive threshold based testing. We envision that the development of this technology will result in a whole family of products that may be used in various vision testing scenarios and applications. In Phase I, we identified most challenging technical requirements of the AVT and demonstrated feasibility of HFR's AVT technology meeting these requirements. We also selected and evaluated major components for the Phase II development. In Phase II, we intend to integrate the selected components into a fully functional TRL-6 prototype that will be delivered to OBVA Laboratory at WPAFB for evaluation.
