          Abstract

          There is a need for displays that can be read even in adverse environmental conditions such as under high intensity, directed sunlight. This is particularly important in self-service terminals that may be placed in an exterior location. These terminals are intended to be used by the general public.

          This paper reports the results of a study comprising of four evaluations of sunlight viewable displays. These evaluations consisted of 16 and 20 participants, with two additional expert reviews. A comparison is made between two different types of display technology, namely, transflective and high-bright backlit displays, and results are presented of this comparison. Secondary comparisons of different approaches for managing glare and reflections are also presented and discussed. Transflective displays were found to be at least as good as high-bright alternatives and are therefore promoted as a viable technology for daylight-viewable displays to be placed in an exterior environment.

          A neurological basis for visual discomfort.

          Certain patterns of stripes are judged to be unpleasant to look at. They induce illusions of colour, shape and motion that are sometimes perceived predominantly to one side of fixation. People who suffer frequent headaches tend to report more illusions, and if the pain consistently occurs on the same side of the head the illusions tend to be lateralized. The parameters of the patterns that induce illusions (including their shape, spatial frequency, duty cycle, contrast and cortical representation) closely resemble those that elicit epileptiform electroencephalographic abnormalities in patients with photosensitive epilepsy. The viewing conditions under which such abnormalities are likely to appear are also those under which more illusions are seen.
