Investigation on the dependencies between hrv, physical training, and focus of attention in virtual environment

Abstract

In this study we investigate the dependencies between human focus of attention and heart rate variability while performing concentration task in virtual environment, using attention improvement device, and taking into account daily physical activity of the participants. For this purpose, a virtual testing environment – football arena – was developed. A volunteer had to “kick” a ball to the gate. He scores a goal if he has reached high attention focus level. The experiments were performed using NeuroSky device for attention level recording, Polar V800 device for heart rate (RR intervals) recording and ElfEmmit device as a better focus stimulator. At the same time, some virtual environment parameters and human action in it were recorded as well. We have used RMSSD parameter as heart rate variability measure. The results showed some unexpected tendencies. RMSSD parameter was in normal range and outside it for both: volunteers who have regular trainings and who do not have any training at all. A tendency was noticed that ElfEmmit device might increase focus of attention during virtual reality game.
