Spatial cognitive training system and experiment validation based on brain computer interface and virtual reality games
[Objective]The purpose of this study is to explore how spatial cognitive abilities in elderly individuals with cognitive impairments can be enhanced through virtual community apartment games,brain-computer interface(BCI),and virtual reality(VR)technology.Spatial cognitive abilities are considered crucial for normal human functioning,particularly for the elderly,and improving these abilities holds significance in enhancing the quality of life.By leveraging modem technological approaches,this research aims to provide new avenues for cognitive rehabilitation,with the expectation of achieving innovative outcomes in medical rehabilitation technology to promote an improved quality of life for the elderly.[Methods]The research method employed in this study was rooted in spatial cognitive theory and leveraged cutting-edge technologies,including virtual reality(VR)and BCI.A virtual community apartment game was designed using the HTC VIVE Focus VR headset,aimed at enhancing spatial cognitive abilities in elderly individuals with cognitive impairments.Participants underwent multiple training sessions within the VR environment,and their performance metrics,including the time required to complete tasks and task accuracy,were meticulously recorded.The BCI aspect of the study involved the extraction of power spectral density features from the participants'brainwave signals,particularly focusing on the Alpha2 frequency band.Support vector machines(SVM)were then employed for classification analysis to discern patterns in brain activity during the cognitive training sessions.[Results]The analysis of behavioral data yielded compelling results.Over the course of multiple training sessions,a significant reduction in the time required to complete tasks was observed,indicating a tangible improvement in cognitive efficiency.Throughout the entire training period,there was a consistent downward trend in the time cost associated with task completion,concurrently with a progressive enhancement in task accuracy.This robust pattern suggested a sustained and effective boost in the participants'cognitive abilities post-training.Furthermore,the examination of brainwave signals in the Alpha2 frequency band revealed a noteworthy increase in the average classification accuracy of SVM.This provided clear evidence supporting the positive impact of the virtual community apartment game on spatial cognition,showcasing a substantial improvement in spatial memory and other cognitive functions as a direct result of the immersive game-based training.In essence,the study's results underscore the potential of VR and BCI technologies in significantly enhancing spatial cognitive abilities among elderly individuals with cognitive impairments.[Conclusions]The study concludes that VR training games based on spatial cognitive theory have a significant effect on enhancing the spatial cognitive abilities of the elderly.The combination of virtual community apartment games,brain-computer interface(BCI),and virtual reality(VR)technology paves the way for new approaches in cognitive rehabilitation and personalized training.This system,grounded in scientific theory and integrating advanced VR technology,is expected to enhance the quality of life for the elderly and drive innovation in medical rehabilitation technology.The research provides empirical support for applying technology to cognitive rehabilitation,offering valuable guidance for future research and practical applications.
