It is beneficial for the information system to provide its users a right amount of contextually important information at a right time. In order to realize this, cognitive and emotional information processing characteristics of a human should be carefully taken into consideration while designing such a system. The objective of the current study was...

  • Feb 2018
We combine eye tracking and a questionnaire-based approach to explore the influence of label density on the perceived visual complexity of maps. We design two experiments in which participants are asked to search for the names of point features on maps and to rate the map complexity and legibility for different label densities. Specifically, we con...
