Crisis management is a time-critical task with high
uncertainty and high risk. Stress and cognitive overload
often result in a set of bias in crisis manager’s
situation understanding and information confirming
processes, known as “tunnel vision”. Aiming at
preventing tunnel vision, we propose an information
assistant system which attempts to reduce the
information quantity, improve the information quality,
and prevent cognitive overload of the user. The main
focus of this paper is to present the design proposal of
the modality planning module. It is one of the modules
which play a role in the prevention of tunnel vision.
The function of this module is to determine the optimum
utilization of the available modalities, in order to
convey information effectively and reduce the cognitive
load of the perceivers. The modality planning strategies
also adapt to the user’s preferences and cognitive
state. pdf
