Activities in the Laboratory

The research and development activity of the Laboratory can be categorized into three main areas: virtual reality and multimedia applications; objective and physical measurement of light emitting diodes (LEDs) and lighting systems; psychophysical experiments in the fields of vision and colour.

Photometry and Colorimetry of Light Emitting Diodes

The Laboratory is well prepared to measure luminous intensity, total luminous flux, luminous intensity distribution, colour and colour rendering properties, ageing and electrical properties of LEDs, LED lamps and luminaires using LED sources. Investigations of such kind are conducted in the frame of several national and international projects.

Psychophysical Visual Investigations

In our Laboratory energy efficient indoor and outdoor lighting systems are developed. We designed optimized LED lamps for home lighting in an international cooperative project. In another international project have been working on museum lighting, using LEDs which are energy efficient, have optimal colour rendering and are safe for paintings. The modern equipment of the laboratory allows the conduction of eye tracking experiments either in real or displayed environments.

Virtual Reality and Multimedia

Our research activity focuses on the development of complex rehabilitation supporting virtual reality and multimedia softwares and also assistance softwares for people with different disabilities. As part of a current research project we are developing such a software to support post stroke rehabilitation. The laboratory deals with applications of multimedia and virtual reality and optic research. Researchers have more than 20 years experience in developing multimedia and virtual reality software for rehabilitation tasks for use by people with disabilities (low vision, hearing impaired, physical and cognitive disabilities, stroke and aphasia patients). Evaluation methods to assess the impact of such software on these user groups are also a research priority. Further items the Laboratory deals with are WEB design and programs for evaluating WEB design from the viewpoint accessibility.


Dr. Cecília Sik Lányi studied Mathematics and Computer Science (M.S.) – József Attila University (1984), and Teacher of Mathematics - Berzsenyi Dániel Teacher Training College in 1988. She obtained the degree of Dr. Univ. at the University of Veszprém, Hungary in Physical-chemistry (1993), and of PhD at the University of Veszprém, Hungary in Computer Science (2000). She has worked as a software engineer and as an associate professor for program languages at the University of Pannonia. Currently she is teaching: Virtual Reality and its application, user interface design, computer graphics for informatics engineering students. PhD and Masters’ supervision has an emphasis on Virtual Reality for the rehabilitation of children with disabilities and patients with mental health issues. She got the “Master teacher” award of the Hungarian Ministry of Education in 2001. She has published more than 300 refereed articles and conference papers, and worked as guest editor for many renowned journals and books. Her research area is Virtual Reality, Human Computer Interaction, Design for All.


This talk is organized by the OutsideTheBox at the Institute of Design and Assessmet of Technology.
