Query: Aging Touch: Systematic and Unbiased Presentation of Tactile Stimuli   This report presents the experimental methodology and a step-by-step guide
for gathering data on how aging influences tactile surface perception in
decision and action. The experiments consist of a set of trials in which the
ability to distinguish tactile stimuli is investigated. A robot arm is used to
provide a systematic and unbiased presentation of the stimuli.
