Abstract
Abstract Computer games have accompanied the development of computer technologies since the very beginning. Despite their basic, purely entertainment-targeted appliance, games can also be used for many other purposes. Medical applications are especially interesting, as games (especially different kinds of simulations) are widely used for training personnel, e.g. to perform certain procedures or in learning to use equipment. This allows the trainees to gain knowledge and proper habits, as well as test themselves in different situations without any risk. Computer games can also be used as a diagnostic tool, although this topic is still insufficiently researched. This paper discusses the possibility of using serious games for diagnosing color vision disorders, focusing especially on two problems: differences in diagnosing colorblindness using 2D and 3D environments, and the influence of individual features, such as reflex or agility, on the diagnostic process.
Highlights
According to popular opinion, colorblindness is the inability to either perceive colors at all or distinguish between red and green
Depending on the disorder type, a person may either not be able to perceive colors at all, or may have a significantly reduced visible color spectrum, or may not be able to distinguish between certain shades of colors (Shevell, 2003)
There are three types of cone cells, which are receptive to different wavelengths of light: in the most basic way we may say that one is sensitive mainly to reds, another to greens and another to blues (Figure 1). Both dichromacy and anomalous trichromacy are divided into three subtypes, depending on the type of retinal cones missing or not working properly
Summary
Total color blindness is an extremely rare condition, affecting from about 0.00001% (cone monochromacy) up to 0.001% (rod monochromacy) of the total human population (McIntyre, 2002). Due to this, it will not be investigated further in this paper. There are three types of cone cells, which are receptive to different wavelengths of light: in the most basic (and simplified) way we may say that one is sensitive mainly to reds, another to greens and another to blues (Figure 1).
