The aim of this paper - based on the extensive experiences of the authors gained by using one particular work simulator - is to present some promising possibilities of the application of this (and any other similar) work simulator in the field of skill assessment, skill development and vocational aptitude tests of physically disabled persons. During skill assessment and development, as parts of the therapy, the focus is on the disabled functions. During vocational aptitude tests, however, the focus is already on the functions that remained intact and therefore can be the basis of returning to work. Some factual examples are provided to realize the proposed possibilities in practice.

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 deficiencies, 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 without a careful statistical hypothesis testing. An appropriate, additional statistical analysis of the distribution of observed errors along the steps of the standard tasks could add further useful information to the obvious results of the study. For this purpose a simple binomial model is proposed, which proved to be applicable in a case study: by the help of this model it was possible to discover some further design failures in addition to the already obvious ones.

This paper addresses the background variables influencing the disabled persons’ motivation to work. Data collection was carried out in Hungary by experts analyzing the change of capability to work on a nationally representative sample. This allows us to highlight also the regional differences, because the motivational status sharply reflected this geographical impact. Besides the socio-economical status, not only motivational readiness was studied, but also factors responsible for cognitive and emotional immunity. Points of intervention were also identified, where the motivation processes could be catalyzed. The aim of this paper is to provide a concise summary of results, to give tentative interpretations and finally to identify practical intervention possibilities to increase handicapped persons’ motivation to work in Hungary.

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 whether the activity is directed predominantly at the process control task, at something else, or miscellaneous. Motivation reflects if the activity is driven by intrinsic or extrinsic motivation. A case study is presented, in which 3 morning, 3 afternoon, and 3 night shifts of a Nuclear Power Plant operator crew are involved. The obtained results gave a deeper understanding of the operators' activity and also revealed an "arousal compensation ” tendency. control room operators ' activity normal operation activity structure activity dynamics 1.

Team working is the basic way of working in the control rooms of hazardous technologies and therefore its quality is a safety-relevant issue. In addition to the technological competence it is also crucial for the crews to have the necessary communicational skills. During simulator training these skills can only be improved if the simulator use is embedded in an appropriate setting. To support this skill acquisition a computer-supported methodology called COSMOS (COmputer Supported Method for Operators' Self-assessment) has been developed. With its help more effective communication and more complete shared mental models can be fostered. This paper is a report on the psychological fundamentals and the mathematical model of the COSMOS methodology.

In Hungary, a lot of electronic-based syllabuses have been developed during thelast 8-10 years at a most considerable cost. However, not much has been heard of theirsuccess or efficiency, as would be supported by scientific testing. First, the present study isto provide a survey of our project, which aimed at creating an integrated electroniclearning environment. The processing of an education technology syllabus integrated in theMoodle virtual learning environment system took place in the passing academic year. Theanalysis of student behaviour in the learning environment is based on log files created onthe server during the course of interaction between learners and the electronic syllabus.We analysed the learning activity of the students in the learning environment in exactnumeric terms by using methods of web-mining. The second part of the study presents someof our first empirical results in this field.

At the Corvinus University of Budapest, a series of experiments was performed, applying the INTERFACE testing methodology developed by researchers of the Budapest University of Technology and Economics. This methodology is capable of recording data characterizing the user’s current mental effort derived from Heart Period Variability (HPV) and the user’s emotional state indicated by Skin Conductance (SC) parameterssimultaneously and synchronized with other characteristics of Human-Computer Interaction (HCI). The current experiments aim to study how the teachers (electronic curriculum designers, developers) themselves use the e-learning development tools to design and edit a new piece of e-learning material.

ABSTRACT The objectives of this empirical study were to contribute to the development of an intelligent, adaptive home lighting system for the elderly. The basic idea was that a carefully chosen dynamic lighting with seemingly ever-increasing (“up”) - or ever-decreasing (“down”) - illuminance can be used to increase (or decrease) the users’ activation level as they wish, a change that will be reflected in objective psychophysiological parameters, in objective performance, and also in subjective feelings. The paper examines the effects of two particular different forms of dynamic lighting – having the same average illuminance over time – on the performance of the number verification task (NVT) by older adults. As a group, the older adults showed no difference between the two forms of dynamic lighting. However, by involving the individual’s sensation seeking needs it was shown that the kind of dynamism influences both the subjective preferences and the objective visual performance. These findings emphasize the importance and sensitivity of individual characteristics of the elderly and have to be taken into consideration for the design of adaptive lighting systems.

Elementary steps of H uman Computer Interaction (HCI), like users' mental actions followed by a series of keystrokes and mouse-clicks, are the basic components of using information technological systems. This is why examination methods capable of assessing users' actual mental effort corresponding to these elementary steps during HCI in a scientifically sound way have great importance. It is known that under certain circumstances, Heart Period Variability (HPV) could be a measure of actual mental effort. This paper gives a short overview of applications of HPV in ergonomics in general and, based on empirical evidence intends to prove that this methodology, after a careful adaptation, could be powerful technique for monitoring mental effort in HCI. The paper outlines the main components of the INTERFACE testing workstation and the related methodology for investigatingamong others-users mental effort. A detailed application example is also provided.

The paper presents the ALADIN prototype for adaptive lighting control designed to assist elderly in achieving a state of well-being, developed as a FP6 EU funded project. It uses psycho-physiological features extracted from Electro-Dermal Activity (EDA) and Pulse signals to determine the subject’s mental state and adapts the lighting parameters in order to achieve a certain desired state. One of the controller implementations was done using Simulated Annealing. Field test evaluations of this implementation are discussed.
