Brain-Computer Virtual Reality Interface System for Brainwave Analysis in Medical Recovery

摘要

Sharp increase and efficiency boost acquired with Virtual Reality (VR) headsets provide limitless opportunities for platform development ranging from training, education, and research. This paper aims to provide a fast solution to contain the hazard created by human error further caused by tiredness and lack of attention and to implement safety measures that detect this type of stimulus and react to it within the operated system. The concentration or focus of a person is measured through the help of brainwaves, which can help to determine if the person is paying attention to the executed task. A persons’ state captured by monitoring the biomedical parameters namely the electroencephalogram (EEG) will act as input data for virtual reality system. The objective of this paper is to create an experimental platform, which shall be able to provide acoustic, visual, and haptic feedback to the user. Whenever his concentration level drops below certain levels, a head-mounted display (HMD) and auxiliary devices particularly used for virtual reality will reflect feedback. If the level of attention is at the lowest limit, the system will initiate safety measures to reach a safe state without taking any risks.
