The strongly limited human capacity for absolute judgements in information transmission tasks leads to the recommendation of a rather small number of coding steps when using single sti

An analytical model of contrast thresholds is presented including the effects of background luminance, size, stimulus duration etc. in order to estimate the

Particularly these results are related to the extraction of contour points, and edges for the reconstruction of the original gray values and the description of forms, and to the e

The results show a good discrimination of different demand levels in very different workload situations. By averaging repeated measurement intervals of short duration the temporal resolut

Recognition rate for small targets does not reach 100%..Accommodation varies around values which shift towards the resting point with increasing unsharpness of targets. Therefore unsharp targets should be avoided. Accommodation sho
