Dynamic visual acuity (DVA) refers to an observer`s ability to resolve a target when there is relative motion between the target and the observer (Cline et al. 1980). According to research findings, this visual attribute has a real potential for the assessment of vision and may play a key role in athletic performance (Hoffman et al, 1981). Unfortunately, the existing DVA measurement apparatuses have important limitations. They are large, complicated to use, and by no means portable. The concept behind this type of devices has not changed much since introduced by Ludvigh and Miller in 1958 (cited by Long, 2002). The observer views a target on a rotating disc with its own methodological shortcomings. Besides, if we consider that in most of sports the ball trajectory does not describe necessarily a circle, we realise they are also very inespecific. To the end to dispose of a more useful instrument, we decided to design and implement the DinVA software.
