A systematic literature review to unveil users objective reaction to virtual experiences: Complemented with a conceptual model (QoUX in VE)

TL;DR

This systematic review analyzes neurophysiological responses to virtual environments, proposing a new conceptual model of user experience with 26 subdimensions, emphasizing the importance of neurophysiological assessments for understanding immersive UX.

Contribution

It introduces a comprehensive conceptual model of UX in VE with 26 subdimensions, filling gaps in existing subjective assessment tools and highlighting neurophysiological measures.

Findings

UX in VE lacks a clear consensus definition.

The proposed model includes 26 subdimensions of UX.

Neurophysiological assessments like EEG and ECG are common, with new methods like brain ultrasound emerging.

Abstract

In pursuit of documenting users Neurophysiological responses during experiencing virtual environments (VE), this systematic review presents a novel conceptual model of UX in VE. Searching across seven databases yielded to 1743 articles. Rigorous screenings, included only 66 articles. Notably, UX in VE lacks a consensus definition. Obviously, this UX has many unique sub-dimensions that are not mentioned in other products. The presented conceptual model contains 26 subdimensions which mostly not supported in previous subjective tools and questionnaires. While EEG and ECG were common, brain ultrasound, employed in one study, highlights the need for using neurophysiological assessments to comprehensively grasp immersive UX intricacies.
