High-resolution vibrotactile spatial acuity dataset for large-area body sites

This xarray dataset ('mvomstein_ds_vibrotactile_spatial_acuity.nc') contains high-resolution vibrotactile spatial acuity data collected from 33 participants across five large-area body sites (forearm, abdomen, lower back near-spine area (NSA), lower back peripheral-spine area (PSA), and thigh). The data were obtained using a fully automated experimental setup that employs Bayesian adaptive parameter estimation to generate continuous psychometric functions. The dataset supports the findings of the study "Data-driven design guide for vibrotactile display layouts by continuous mapping", which is published at Scientific Reports (Nature Research). Additionally, the supplementary files ('mvomstein_[...].xlsx') provide statistical analyses for the figures presented in the manuscript, including detailed results for comparisons across body sites, anisotropy effects, and regional sensitivity gradients.
