Abstract

Discrete Fitts pointing tasks are traditionally used to model Fitts’ law. Therefore, as task has many uses in psychological research, especially pertaining to human-computer interaction it is important to understand the effects this task may have on participants. The present study sets out to quantify the stress response of this task on three spectrums: 1) Physiologically through recorded heart-rate variability monitored through an EKG, 2) Cognitively through assessment of speed (reaction time) and accuracy during an N-Back task, and 3) Subjectively through participant self-report surveys for worry, engagement, distress (DSSQ), and subjective workload (NASA-TLX). Results have found an increase of stress throughout a discrete pointing tasks and the effects increasing as a function of difficulty.
