Abstract
Effective, accurate and fast process of multimedia
stimuli generation, implemented as a computer
system, is very useful to domain specialists
in the fields of psychology, psychiatry and
neuroscience in selecting and displaying
excitation sequences, and as an aid in estimating
the cognitive and affective parameters of the
subject. The primary purpose of this paper is to
present a computer system for multimedia stimuli
generation and neurofeedback developed by
the authors. The computer system is used with
affective multimedia databases and is intended
for research of emotions and attention, and for
some types of psychotherapy with a behavioral
component. The computer system was tested in an
emotion elicitation experiment in virtual reality
environment with 6 subjects. The eMotiv EPOC
+ 14-channel mobile EEG and HTC Vive virtual
reality device were used. The pictorial stimuli
were downloaded from the NAPS affective
multimedia database and two sequences were
generated with a total of 20 pictures to elicit the
basic emotions of sadness and happiness. The
results of the experiment confirm the correctness
of the design and implementation of the computer
system of the multimedia stimuli generator.
