In recent years, the study of the human colour vision system in the chromatic-frequency domain has been a source of interesting results, concerning especially the spectral modulation sensitivity function (SMSF). Here, we present a detailed study of the mid-frequency range of this function for two normal observers and also the SMSF for two observers with colour-vision deficiencies (protanopes). ...

The contributions of genetics research to the science of normal and defective color vision over the previous few decades are reviewed emphasizing the developments in the 25years since the last anniversary issue of Vision Research. Understanding of the biology underlying color vision has been vaulted forward through the application of the tools of molecular genetics. For all their complexity, th...

We have used the Farnsworth-Munsell 100-hue (FM 100) test and Mollon-Reffin (MR) test to evaluate the colour vision of 93 subjects, 30.4 ± 9.7 years old, who had red-green congenital colour vision deficiencies. All subjects lived in Belém (State of Pará, Brazil) and were selected by the State of Pará Traffic Department. Selection criteria comprised the absence of visual dysfunctions other than ...

PURPOSE The purpose of the study was to examine possible persisting effects to color vision in a group from the Royal Australian Air Force who had exposure to formulations containing neurotoxins during F-111 fuel tank maintenance, relative to two contemporaneous comparison groups. METHODS Color vision was tested in 512 exposed personnel, 458 technical-trade comparisons, and 330 non-technical ...

In this paper, we present a novel methodology to evaluate the accessibility of products using virtual prototypes. The novelty is that the product evaluation is based on simulating the interactions of users with physical deficiencies in virtual and immersive environments. Virtual users with special needs, e.g. elderly or impaired people, were modelled using both literature data and real subjects...

Usher syndrome 1 (USH1) is the most common and severe form of hereditary loss of hearing and vision. Genetic, physiological, and cell biological studies, together with recent structural investigations, have not only uncovered the physiological functions of the five USH1 proteins but also provided mechanistic explanations for the hearing and visual deficiencies in humans caused by USH1 mutations...

This paper analyzes the present situation of cooperative education in China’s art disciplines, points out deficiencies during development and puts forward some countermeasures suggestions based on its approach “introduction, integration innovation” while studying case Birmingham Institute Fashion Creative Art. It aims to cultivate a group new design talents with creativity, practical ability in...
