However, the mere provision of a DSS may not be sufficient to facilitate beneficial work outcomes because employees often do not rely on a DSS. Therefore, we examined whether users' trust in a DSS increases positive effects of DSS provision on several core work outcomes (i.e., performance, well-being, and release of cognitive capacities). Moreover, we examined whether trust effects on these work outcomes depend on specific context conditions (i.e., user accountability, distraction, and market dynamics). We tested our hypotheses in a laboratory experiment with N = 201 participants who received assistance by a DSS in a simulated sales planning scenario. In line with our assumptions, trust in the DSS was positively related to users' performance and well-being. Moreover, the link between trust and strain as well as release of cognitive capacities were qualified by distraction, so that higher distraction diminished these links. No such moderation occurred for user accountability and market dynamics.","PeriodicalId":298769,"journal":{"name":"Proceedings of Mensch und Computer 2020","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116635575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For a more differentiated perspective on presence, the term can be defined by subtypes, such as physical, social and self-presence. The Multimodal Presence Scale (MPS) by Makransky and colleagues deals with these dimensions, was translated into German, and evaluated regarding the sensitivity and specificity of the social presence subscale. The results raise the question how well differences in physical and self-presence can be detected by the scale. We conducted an experiment by constructing two virtual worlds, manipulating the polygon count of objects in each world, and measuring presence. Additionally, we assessed the correlation of the MPS with the Igroup Presence Questionnaire (IPQ). No significant differences in physical or self-presence were found. However, when examining an item that closely matches the manipulation of the self-presence world (the user's virtual hands), a statistically significant difference was found. We provide three possible explanations for these results: 1) an insufficient impact of the abstraction levels, e.g., due to insufficient time and attention to the manipulation, or too little difference between the abstraction levels, 2) a lack of sensitivity of the used MPS and IPQ, or 3) the polygon count not being important for physical or self-presence. We conclude that high polygon count might not be that crucial for presence and provide suggestions for future research.","PeriodicalId":298769,"journal":{"name":"Proceedings of Mensch und Computer 2020","volume":"644 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123284983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has shown that virtual reality (VR) can provide stimulating experiences, elicit positive emotions, and provoke relaxation. In this paper, we present an approach that integrates stimulating cognitive tasks, playful elements, and virtual natural environments in one VR app tailored for elderly people. We developed a virtual walk in the forest where the players can solve cognitive tasks in two mini-games. To support a feeling of social presence and to reduce loneliness, we integrated a virtual dog as a companion who accompanies the players. We conducted an evaluation with 14 participants aged 66 to 84 years. The results show a change of positive and negative affect scores after using the VR experience. That supports our assumption, even though the differences were not significant. The participants enjoyed the VR app and were especially impressed by the experience of presence. Despite their inexperience in using VR technology, the participants behaved naturally and were interested in using it again. Our results support the assumption that elderly people can benefit from VR games in their everyday lives.","PeriodicalId":298769,"journal":{"name":"Proceedings of Mensch und Computer 2020","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116700221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
