Spatiotemporal Clustering of Human Locomotion Neuropsychological Assessment in Virtual Reality Using Multi-step Model
This paper introduces a spatiotemporal clustering model to analyze neuropsychological assessments conducted in a virtual reality environment. The study focuses on clustering human navigation behaviors using a deep learning framework that separates feature extraction and clustering stages. By applying a 1D-DCAE autoencoder for feature extraction and a soft temporal clustering mechanism, the method identifies five distinct clusters corresponding to clinical groups. This research contributes to understanding navigation patterns in cognitive impairments and advances VR-based neuropsychological assessments.
