A Systematic Review of Physiological Measurements, Factors, Methods, and Applications in Virtual Reality

Measurements of physiological parameters provide an objective, often non-intrusive, and (at least semi-)automatic evaluation utilization user behavior. In addition, specific hardware devices Virtual Reality (VR) ship with built-in sensors, i.e. eye-tracking movements sensors. Hence, the combination measurements VR applications seems promising. Several approaches have investigated applicability benefits this for various fields applications. However, range possible application fields, coupled potentially useful beneficial parameters, types sensor, target variables factors, analysis techniques is manifold. This article provides a systematic overview extensive state-of-the-art review usage in VR. We identified 1,119 works that make use Within these, we 32 focus on classification characteristics experience, common The first part categorizes by field application, therapy, training, entertainment, communication interaction, as well factors measured parameters. An additional category summarizes general applicable to all since they typical qualities. second review, analyze regarding respective methods used automatic and, potentially, classification. For example, highlight which measurement setups been proven be sensitive enough distinguish different levels arousal, valence, anxiety, stress, or cognitive workload virtual realm. work may prove researchers wanting data who want good prior taken, their potential drawbacks.
