Abstract [en]

In addition to normal reading, knowledge can be gained from a paper document by pattern recognition and encoding of characteristics of the information media. There are reasons to believe that this can be done automatically with very little attentional demand. The knowledge gained is accessible to consciousness and can be used for task components like orientation, navigation, detection of changes and as a complement to normal reading. When information is computerized, and is read from a screen instead of from a paper, the conditions for automaticity are often radically changed. In most casesthe reader has to gain the corresponding knowledge by effortful cognitive processes. This means adding to the cognitive load leaving less attentional capacity for the main task at hand. This problem can be avoided by a careful analysis of a reading task into its automatic and non-automatic components, followed by a dedicated user interface design where information relevant for orientation, navigation etc is presented in a way that the reader can perceive rather than read.
