| Summary: | <h4>Objective</h4>To understand the impact of fidelity and perceived realism on virtual reality food choices, and task motivation, engagement, and interest.<h4>Design</h4>Randomized controlled trial.<h4>Setting</h4>Online.<h4>Participants</h4>84 participants recruited from Amazon Mechanical Turk.<h4>Intervention</h4>Participants were randomly assigned to either a high- (n = 43) or a low- (n = 41) visual fidelity environment and were asked to select foods to have a meal with a friend.<h4>Main outcome measures</h4>Food choice, motivation of food choices, engagement, and interest.<h4>Analysis</h4>Simple linear regressions between visual fidelity and perceived realism, and log-linear regressions for visual fidelity or perceived realism on either motivation, interest, or engagement. Poisson models between visual fidelity or perceived realism, and food selections.<h4>Results</h4>Manipulating visual fidelity was not associated with perceived realism, motivation, interest, or engagement in the food selection task. Perceived realism increased motivation by 0.3% (SE 0.056; p = 0.022), interest by 1.4% (SE 0.002; p<0.001), and engagement by 0.9% (SE 0.001; p<0.001) in the food selection task. High visual fidelity decreased the total number of foods selected (B = 0.216; CI (-0.384; -0.047); p = 0.012).<h4>Conclusion and implications</h4>Perceived realism, but not visual fidelity, is important for task related factors like motivation, engagement, and interest. Visual fidelity may influence some food selections. |
