This study assesses the effects of colour-blindness on casual computer gaming performance and experience. Participants played an online puzzle game in both an unmodified environment and in a colour-blind simulation. Some of our results suggests that the colour-blind filter did not negatively impact player performance. However, post-test questionnaires reveal that users perceived the game to be ...

We have developed 3 series of pseudoisochromatic plates for colour vision testing. The plates are arranged in order of increasing difficulty. In the first (red/green) series, a red Landolt C is shown in front of a green background. This series is used to determine the severity of colour vision deficiency. In the second series, colours are located on the protan confusion line, whereas in the thi...

BACKGROUND Two practical color vision tests were developed and validated for use in screening Air Traffic Control Specialist (ATCS) applicants for work at en route center or terminal facilities. The development of the tests involved careful reproduction/simulation of color-coded materials from the most demanding, safety-critical color task performed in each type of facility. METHODS The tests...

Color vision deficiency (CVD) is quite common since 8%-12% of the male and 0.5% of the female European population seem to be color-blind to some extent. Therefore there is great research interest regarding the development of methods that modify digital color images in order to enhance the color perception by the impaired viewers. These methods are known as daltonization techniques. This paper d...
