Table 14: Effects of conditions (technology and user profile) on the sense of presence. Regarding technology conditions, eight studies found that relationships existed between sense of presence and study conditions. Studies [31; 59; 60] found that using multiple audio channels increased presence over mono and stereo sound. This highlights the importance of auditory richness for enhancing sense of presence. In addition, [9; 59] found that spatialized sound, which helps interpret sounds in relation to a space, potentially increases presence. However, in the absence of this characteristic, study [9] demonstrated that presence is enhanced by the use of sound. Similarly, studies [1; 12] revealed that virtual reality evoked more presence than other, flat screen, media. Curiously, study [1] argued that this relationship can be mediated by the built environment used, where MIP scenarios of sadness produced higher presence results in flat screen media than was produced by HMDs. Study [19] also reported complex interactions between sense of presence and point of view mediated by the projection center in an indoor environment. The authors of this study also highlighted that participants had a slight preference for virtual environments with a shorter focal length, which generates a visual effect of greater depth. The examination of indicators used to evaluate sense of presence identified seven studies that established relationships between presence and conditions (technology and user profile). Studies [9; 31; 60] revealed that users' perceptions of realism and sound localization were improved in spaces incorporating audio support with more channels
