简介：

Overview

This article presents the tactile semiautomated passive-finger angle stimulator (TSPAS), a novel method for assessing tactile spatial acuity and angle discrimination. The system applies raised angle stimuli to a subject's passive fingerpad while controlling for movement speed, distance, and contact duration.
