A Random Dot Stereoacuity Test based on 3D Technology

This paper presents a novel stereo acuity test that is real-ized by a software program on a PC with 3D capabilities. The 3D technology is used to provide two separate images to the two eyes. The test is a classical random dot test, but differently to other test printed on paper, the images shown to the patient can vary and there is no monocular clue. These features allow to deliver the test also in groups (instead of individuals) like school classes, and to increase the sensitivity. The system can be easily used also by not specialized personnel and this may further increase the cost efficiency of the test. Experiments carried on with a large set of children of age between five and seven years are pre-sented. The obtained results are discussed through some comparisons between traditional approach and our innova-tive idea
