You gained the ’Excellent
Lecturer of BME’ prize. How did you take this honour?
It surprised me. It was just a few weeks ago, that I received an email
from the students’ union of BME, informing about the prize. I felt delighted
and pleased that I got the award based on the students’ assessment of
lecturers. However, I did not expect it.
What could be the key to that you
were given the prize?
This prize was given for lecturers ranked highly by
more than 100 students for two consecutive semesters in the 2018/2019 year
survey filled by students. The reason could be, perhaps, that I handle students
as equal partners. This prize is, although, not only my honour. I give lab courses,
where it is much easier to connect and get feedback. It is less rewarding to
speak for an hour and a half in front of hundreds of people.
In the project Odoo, you have
participated as a masters student back then. As a part of the team responsible
for lighting, what was your role?
In the Odoo project, we had to create an innovative
residential house according to a strict set of rules, which was great teamwork.
At the lighting design, we aimed, that the items and the functions should
complete each other as much as possible, as we focused on sustainability. On
the other hand, we had to design for a small area. So, there was no need to
think about numerous separate chandeliers, for instance.
You also study colour adaptation.
What does it mean?
The beauty of this topic is that it is practically
experienced by everyone having the ability to see in colour. The colour
adaptation (or, more precisely, on its scientific name, chromatic adaptation)
is a process when we adapt to changes in the light. We only perceive that our
visual system would automatically set the white balance. When wearing coloured
glasses, or arriving from natural light to a place with artificial light may
seem unusual first, but we adapt later on. What I research is the processes
going on in our visual systems and brain, meanwhile adapting.
What kind of processes is going
on?
If there is a change in the lighting, besides, that we
see a white surface white again after a while, all other perceived colours can
change, and so maybe we won’t be able to notice such differences, which we
noticed before. But, we do not necessarily see this change. The colour of the
objects always depends on the lighting: we should buy used cars in spring or
summer, in sunlight, because in such circumstances, the repainted particles can
be noticed more easily. But also, clothes have a different colour in daylight,
then in a shop window with LED lighting.
Although my PhD research is about chromatic
adaptation, I do handle other phenomenons as well. The Optics Team of the
Department is outstanding, we research diverse topics, while we are not many.
So, in several projects, like sight examinations or industrial problems, I do
not only have an insight, but my colleagues count on my work there.
Do you have further plans?
My plan number one is
gaining my doctoral degree; my doctoral act is in progress. I’d like to stay at
the Department, making this step forward more essential.
(At the end of the interview,
Ágnes Urbin showed two experiments to the writer of the present lines. In the
first one, taking place at a booth-like box, I had to place twenty coloured cylinders
between a mauve and a green one, in the sequence of their colour. Then we
repeated it in green lighting. The right sequence was on the back of the
cylinders.
In the other one, I had to sit in
front of a monitor, showing coloured spots, like the Ishihara test, used for
diagnosing colour vision deficiency. In the middle of the picture, the spots
formed a ring with a gap, like a letter ’C’. Ágnes Urbin gave me a remote
controller with four buttons, from which I had to press one, depending on the
direction of the hole on the picture.
After the experiment, I did not
only got to know, that I do not have a colour deficiency but also, that the
most of the people having the ability to see in colour, press the button in the
right direction for a while, even if they feel totally insecure.)
