Deducing User’s Fatigue from Haptic Data

Abdelwahab Hamam

Abstract:

Undesired physical fatigue reduces the overall Quality of
Experience (QoE) of virtual reality haptics applications. Detecting
fatigue is the first step in rectifying this problem. Fatigue in
usability analysis is usually detected through conducting
questionnaires and observations. This paper introduces an
objective indirect discovery of user’s fatigue through analyzing
data of a haptic writing application. Our results show that if users
are feeling tired their kinetic energy would decrease. We can
compute this kinetic energy from the velocity of the arm
movement during the usage of the haptic device.
