Efficiency of visualization interfaces in terms of their users' decisions speed and accuracy in safety-critical areas is extremely important as late or wrong reaction on displayed information may cause at least financial losses (not to mention the damage to human health and/or environment). Users of such systems can be overloaded with the displayed information and therefore it can take them more time to make a decision. In this paper, a novel visualization interface is presented, that can detect its user's cognitive overload and adapt the amount of information to be displayed and its visualization according to user’s current cognitive capabilities. Results provided by the conducted user study have demonstrated that such adaptation technique benefits visualization interface efficiency.
