For multi-channel information systems it is often relevant to model where something is supposed to take place, but business process modelling notations seldom capture geographical location. In previous papers, we suggested and compared alternatives for small modifications to UML Activity Diagrams to address this, and a controlled experiment indicated that an alternative using colour performed better than one using annotations. However, colour also has some challenges, especially concerning users with colour vision problems. Hence, this paper reports on a new experiment comparing colour with black/white pattern fills. The experiment investigated both the participants’ opinions about the notations and their performance on some tasks. While opinion was significantly in favour of the colour notation, task performance was only slightly in favour of this notation, and not significantly so.Read the full paper here: https://link.springer.com/chapter/10.1007/978-3-642-21759-3_23
