As users are highly impacted by stress or cognitive overload, a single click is the most complex interaction that can be expected. This can be taken as a confirmation of intent, resulting in fully automated information gathering. This means that all mechanisms responsible for gathering data can be activated.
Guided interaction
As users are not directly impacted by the incident anymore and cognitive workload is available again, more focused interaction can be expected (but not too complex). This can be implemented through simple multiple-choice selection, where the user is guided to a possible answer by being confronted with various answers. By recognizing the correct (or most suitable) answer, the user is able to provide more precise information about the incident.
Chat interaction
Unstructured/open information. Having almost their complete cognitive power available, users can execute more complicated tasks. This means reacting to individually defined tasks or providing a description in plain text. Here, basically all interaction possibilities can be integrated into the app.
