A Fuzzy Logic System for Evaluating Quality of Experience of Haptic-Based Applications
Multimedia systems and applications have recently started to integrate the sense of touch and force feedback in the human-computer interaction. Surprisingly, measuring the quality of experience (QoE) when haptic modality is incorporated in a virtual user interface has received limited attention from the research community. In this paper, we propose a taxonomy for measuring the quality of experience of Virtual Reality (VR) applications. Furthermore, the taxonomy is modeled using a Fuzzy Logic Inference System (FIS) to quantitatively measure the QoE of a haptic virtual environment. Finally, the proposed model is tested using the Mamdani system. The simulation and usability analysis demonstrated that the proposed model reflects the user estimation for the applications more accurately and thus is capable of measuring the overall QoE of a haptic application.
