We evaluated the visual fatigue in a binocular disparity type 3-D dispaly system. Currently, 3-d display systems are spreading to various applications such as medical equipment and amusement games. However, they are known to cause visual fatigue in users. To evaluate this fatigue, we focus on the mismatching between convergence and accommodation, since it is a major problem with binocular disparity type 3-D displays. This paper reports the basic idea of evaluation, subjective assesment for this evaluation and current result of assessment. For this subjective assessment, we use a newly-developed binocular disparity 3-D display system with a compensation function for accommodation. Because this equipment only allowed us to compare the terms of the mismatching itself, the evaluation is more accurate than similar previous works. As a result of this measurement, we were able to confirm the effectiveness of the indexes and the method of measurement, and could also quantitatively explain the influences of the mismatching on the accommodation function.
