Nowadays VR technologies are becoming more and more popular, partly because
we can experience the virtual reality without possessing expensive devices, for instance
we can enjoy VR on our smartphones with the help of the Google Daydream tool. Besides
the traditional VR control, there is a new approach, in which the game can change itself
depending on the user’s state of mind. This technology is called biofeedback control, and
it is able to process the brain signals, with head-fitted EEG sensors. Sensor
implementation has been solved with compact, non-expensive headsets, such as
NeuroSky MindWave tool, which can monitor the concentration and the relaxation level
of the user.
In my project I created a game, which uses the advantages of the biofeedback as
widely as possible. The main purpose of the game is to entertain, but it is also suitable for
special pedagogical researches with the help of the Frostig tests hidden in the game.
The game is a zombie survival game, in which the player must solve missions by
moving forward along a predetermined path. The game is able to process the user’s state
of mind in real time, and change its own state based on the information. With this
technique the user is less likely to get bored with the game too early, and we can also
keep the user relaxation value low. The data measured during the Frostig tests can be
used for any research purposes.
