✦ Synopsis
nique improved symbol recognition performance. In the first study the size enhancement was between 60-75% in total number of pixels for the critical feature. The amount of size enhancement was limited by the display surface area. In the second study, a new method of size enhancement was utilised, whereby the longest axis of the critical feature was increased by 0.10 in (2.5 mm). In this study, there was no display surface constraint. In both studies, colour coding of the critical feature was also evaluated. The results of the first study indicated that only the colour coding technique was significant. In the second study, both colour coding and size enhancement were significant. It was concluded that in the first study the way in which the size enhancement was applied to the critical feature (an increase in total surface area) was not sufficient to achieve a unique symbol, so it did not improve the subject's recognition ability; however, in the second study, size enhancing the longest axis was sufficient to result in a performance payoff.
