Determinants of Adopting Wearable Devices for Non-Immersive Virtual Reality Upper Limb Training Systems: An Interaction Experience Perspective

Determinants that influence users' behavioral intentions in adopting non-immersive virtual reality training systems remains unclear from the perspective of the interaction experience. Based on the stimulus-biological-response framework, a hypothetical model was constructed by integrating, refining, and dismantling three related theories to investigate the behavioral intentions of users adopting wearable devices for non-immersive virtual reality upper limb training. Structural equation modeling and necessary condition analysis (NCA) were used to analyze and interpret 182 data points. Perceived interactivity and spatial presence affected experience dimensions significantly. Arousal had no significant effect on focused attention. Experience was influenced by perceived interactivity for males and spatial presence for females. NCA results verified the influence of each dimension on behavioral intention versus the actual threshold. Stakeholders should consider the positive effects of perceived interactivity and spatial presence on the different experiential dimensions. The effects of different experiential dimensions on behavioral intentions should also not be ignored.
