Universal Design Of Smartphone User interface Interaction in Stressful Situations

Abstract

Previous research has investigated how high values of cognitive load contributes to an increased stress level, yet there are still limitations on how stress affects our cognitive load when it is initially low. That is mainly what this project attempts to address by using Heart Rate Variability as an index of stress and Galvanic Skin Response (GSR) as an index of cognitive load, which has been designed and developed by us for this project purpose. Stress is also very much based on individual preferences and while similar studies lack this kind of an approach, this study presents an experimental design of creating an individual stress template for this assessment. Studies in this field is also usually limited to a controlled laboratory environment, whereas this project proposes an experimental method which investigates and determine when cognitive load and stress reaches a high/low level, while interacting on mobile interface in a real-life scenario.
