Hello! I am a master's student and I am trying to replicate this study on SmartPLS which evaluates the impact of augmented reality on UX and its outcomes on user satisfaction and willingness to buy. I don't understand how augmented reality is put in the model (I state in advance that I am not a professional in statistics and SmartPLS so maybe my question sounds foolish). I can say it's a grouping variable (because there are two treatments, the control and experimental group), but how can I assess the Hypothesis "AR significantly and positively impact UX"? In the paper, it's written that AR is used as a stimulus but again I don't get how I can use it in my model. Hope my question is clear enough, and thank you in advance for the help.
