摘要：An objective and advantage of Virtual Reality is to promote the sense of “being there”, to be present. Most existing research in this field is focused on determining “if” a given factor contributes to the sense of presence. This paper compares two visualization systems regarding their contribution to the sense of presence, assessing which one contributes the most. Two low-cost low-tech systems were considered: anaglyph-based stereoscopy and large Field-of-View (FOV) screens. The SUS Questionnaire was applied to 63 participants to assess their sense of presence. Participants were divided in two groups on a between-subject experiment and watched a guided tour on a virtual University campus. It was found that both systems contribute to increase presence, but data shows that anaglyph-based stereoscopy contribute more than FOV enlargement. We conclude by suggesting that the very first step to raise the immersion of a Virtual Environment should be using stereoscopy, at least the anaglyph-based one
