Our HCI group developed mutually useful relationships with industrial partners, like MATÁV Hungarian Telecom, Paks Nuclear Power Plant, Graphisoft, Nokia, EuroControl, etc., successfully accomplishing various R&D projects in very different fields.We apply a variety of evaluation methods, including a complex methodology called INTERFACE developed by(More)
In laboratory usability studies, error collecting and analysis are frequently used methods of software evaluation and usually are capable of revealing the most conspicuous design de® ciencies, if there are any. In certain cases, however, it is hard if not impossible to distinguish accidental user errors from systematic errors attributable to design failures(More)
Earlier publications have shown that a Heart Period Variability (HPV) -based methodology, after careful adaptation, could be a powerful technique for monitoring mental effort in Human-Computer Interaction. This paper outlines the INTERFACE testing workstation developed by researchers of our department. This system is based on the simultaneous assessment of(More)

An activity analysis method was developed for studying the structure and dynamics of control room operators' activity during normal operation based on directly observable elements of the operators' behavior. The method assesses current activity along three dimensions in each 5-min period of the shift. Intensity characterizes arousal level, direction shows(More)
