Also exergames, which refer to computer games combined with a physical activity, are getting widely available, driven by developments in sensor technologies. In this paper, we present results of a multiplayer exergame experiment where two players race against each other four times on two rowing ergometers. Experimental conditions were type of environment (with VR vs. without VR) and the possibility of conversation with the opponent (conversation enabled vs. conversation disabled). To measure subjective experience, participants rated perceived flow, sense of presence and social presence on standardized questionnaires. Results show that the type of environment has a significant influence on the perceived presence, as participants rated the presence higher in VR. The possibility of conversation resulted in a perception of a significantly higher social presence. This illustrates that the usage of virtual environments as well as the possibility of conversations between users are highly valuable to increase the Quality of Experience during exergames. In our future research, we plan to further investigate means to improve the user experience by applying gamification, different representations of opponents, and to assess the impact of network impairments during multiplayer scenarios.","PeriodicalId":6618,"journal":{"name":"2018 Tenth International Conference on Quality of Multimedia Experience (QoMEX)","volume":"30 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79018189","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}

In addition to the common “star rating” used to estimate Mean Opinion Score (MOS), more detailed survey questions (problem tokens) about specific areas provide valuable insight into the factors impacting QoE. This paper explores two aspects of problem token questionnaire design. First, we study the bias introduced by fixed question order, and second, we provide a methodology to manage the size of the survey while keeping it informative. Based on 900,000 calls gathered using a randomized controlled experiment from Skype, we find that token selections can be strongly biased due to token positions and display design. This selection bias can be significantly reduced by randomizing the display order of tokens. It is worth noting that users respond to the randomized-order variant at levels that are comparable to the fixed-order variant. The effective selection of a subset of tokens is achieved by extracting tokens that provide the highest information gain over user ratings. This selection is known to be in the class of NP-hard problems. We apply a well-known greedy submodular maximization method on our dataset to capture 94% of the information using just 30 % of thequestions.","PeriodicalId":6618,"journal":{"name":"2018 Tenth International Conference on Quality of Multimedia Experience (QoMEX)","volume":"49 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75317675","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}

To this end, we present the results of a lab-based QoE study featuring a virtual manufacturing training setting in which participants were asked to correctly allocate spare parts to mounting locations inside and outside a vehicle using an HTC Vive VR Setup. We evaluate how five different rendering styles (defined by rendering technique and shader used), ranging from point cloud to highly photo-realistic, affect different quality dimensions such as perceived visual quality, task difficulty, spatial orientation ability, and discomfort (including cyber-sickness). Our results show that while rendering style has a significant impact on QoE and other dimensions (like task completion time), a standard shader already can provide sufficient quality to support the provided training task and can even outperform rendering styles using more sophisticated techniques like ambient occlusion. Furthermore, we also discuss significant influence of user-related factors like previous experience with VR or gender as well as other related critical issues to be considered in VR training application and assessment study design.","PeriodicalId":6618,"journal":{"name":"2018 Tenth International Conference on Quality of Multimedia Experience (QoMEX)","volume":"183 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74646336","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}
