Method & Evidence

AimCan the TOPSIS model provide a more precise and reliable method for evaluating user presence in virtual reality systems compared to traditional weighted sum approaches?

MethodQuantitative user study with comparative analysis

ProcedureParticipants completed 12 tasks within a self-developed VR swimming system. User presence was evaluated using the Group Presence Questionnaire, with results analyzed using both a weighted sum approach and the TOPSIS model. Two weighting methods (fuzzy hierarchical analysis and uniform weighting) were applied within the TOPSIS framework. The precision of the evaluations was compared based on the range of data within a 95% confidence interval and the coefficient of variation.
