In fact, the QoE has allowed to extend the concept of image quality by considering other aspects to evaluate \"the delight or annoyance of a customer's experiences with a service\" [1]. The concept of QoE is extremely important since it has a big impact on several fields, ranging from the acquisition to the rendering of multimedia contents. Many works can be found in literature that address the problem of evaluating the QoE for 2D and 3D contents but nowadays we are facing a new challenging task: to study the QoE for immersive media. When talking about immersive media we are referring to different types of multimedia that allow the users to explore the content in their personal way thus introducing a new and important variable to be considered while evaluating the QoE. In particular, recent years have witnessed the spread of Virtual and Augmented Reality that allow the users to be involved in a more realistic and deep way in the artificial multimedia content or to interact with virtual objects [2]. In this new scenario we are moving to the concept of \"personal\" QoE that encompasses many open questions that are still unanswered such as: which is the impact of the rendering system on the QoE, how important are the viewing conditions, how can we account for the immersive media content way of exploration, can the study of multimedia saliency help in understanding the QoE [3]? In this talk we will address these open questions to explore what are the current research findings and trends and I will give you an insight of what will come next.","PeriodicalId":402203,"journal":{"name":"Proceedings of the 1st Workshop on Quality of Experience (QoE) in Visual Multimedia Applications","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121907739","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}

Because cloud gaming possesses the merit of lifting computation loads from client devices to servers, it solves the high resource consumption issue of VR games on regular clients. However, it is important to know where is the bottleneck of the cloud VR gaming platform and how can it be improved in the future. In this paper, we conduct extensive experiments on the state-of-the-art cloud VR gaming platform--Air Light VR (ALVR). In particular, we analyze the performance of ALVR using both Quality-of-Service and Quality-of-Experience metrics. Our experiments reveal that latency (up to 90 ms RTT) has less influence on user experience compared to bandwidth limitation (as small as 35 Mbps) and packet loss rate (as high as 8%) . Moreover, we find that VR gamers can hardly notice the difference between the gaming experience with different latency values (between 0 and 90 ms RTT). Such findings shed some lights on how to further improve the cloud VR gaming platform, e.g., a budget of up to 90 ms RTT may be used to absorb network dynamics when bandwidth is insufficient.","PeriodicalId":402203,"journal":{"name":"Proceedings of the 1st Workshop on Quality of Experience (QoE) in Visual Multimedia Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128354876","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}

With the exponential growth of users, published mobile games, and higher expectations for gaming experiences, multi-dimensional aesthetic assessment is essential in providing guidance for graphic/game developers, quality control of the overall gaming system, and achieving a better trade-off between gaming image quality and the rendering complexity (limited by the device performance). So far, most of the relative researches have been limited to only one dimension evaluation e.g., quality assessment considering streaming artifacts, which neglects other important aesthetic-related perspectives. In this paper, a comprehensive subjective study is presented considering multi-dimensional aesthetic factors (i.e., the fineness, color harmony, colorfulness, and overall quality) of mobile gaming images. Throughout extensive conducted experiments on the collected large-scale dataset, we discuss the relationships between different dimensions, and benchmark different image metrics designed for various purposes.","PeriodicalId":402203,"journal":{"name":"Proceedings of the 1st Workshop on Quality of Experience (QoE) in Visual Multimedia Applications","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126480147","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}

Viewport-driven tiling schemes have been introduced in 360° video processing to provide high-quality video streaming. However, treating viewport as traditional streaming screen results in frequently rebuffer or quality distortion, leading to poor Quality of Experience (QoE) of schemes. In this paper, we propose Viewpoint Movement Perception 360° Video Streaming (VMP360), an adaptive 360° video streaming system that utilizes unique factors of 360° video perception quality of users to improve the overall QoE. By studying the relative moving speed and depth difference between the viewpoint and other content, the system evaluates the perceived quality distortion based on optical flow estimation. Taking QoE into account, a novel 360° video quality evaluation metric is defined as Optical-flow-based Peak Signal-to-Noise Ratio (OPSNR). Appling OPSNR to tiling process, VMP360 proposes a versatile-size tiling scheme, and further Reinforcement Learning (RL) is used to realize the Adaptive Bit Rate (ABR) selection of tiles. VMP360 is evaluated through the client-server streaming system with two prior schemes Pano and Plato. Statistics show that the proposed scheme can improve the quality of 360° video by 10.1% while maintaining same rebuffer ratio compared with the Pano and Plato, which confirms that VMP360 can provide a promising high QoE for 360° video streaming. The code of a prototype can be found in https://github.com/buptexplorers/OFB-VR.","PeriodicalId":402203,"journal":{"name":"Proceedings of the 1st Workshop on Quality of Experience (QoE) in Visual Multimedia Applications","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128465633","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}
