Närvarokänsla i virtuella miljöer : En studie av utmaningar vid mätning av närvarokänsla
Sammanfattning: This paper investigates problems connected to measuring presence in virtual environments through analyzing an investigation about what importance the level of detail has for the sense of presence. This is done by performing an experiment, testing participants’ sense of presence in two versions of one scenario where one has a high level of details and one has a low level of details. To measure the participants’ level of presence two methods were used, one subjective method and one objective method. The result of the experiment showed that the level of details doesn’t have a significant importance for the sense of presence which surprised both us and our employer. A problem found surrounding the measuring of presence was that there are different levels of presence which in turn require different methods of measurement. The challenge lies in identifying what kind of presence you want to measure and then base the method on that. Subjective presence requires subjective measures and objective presence require objective measures. Also, it is possible that presence may not always be the thing to measure when it comes to user experience in a virtual environment. The purpose of the virtual environment needs to be identified before one can decide whether the sense of presence is relevant or not. When virtual reality is used in commercial purposes there are probably other aspects that are more important than the user’s sense of presence.
