With the spread of the broadband Internet and highperformance devices, various services have become available anytime, anywhere. As a result, attention is focused on the service quality and Quality of Experience (QoE) is emphasized as an evaluation index from the user’s viewpoint. Since QoE is a subjective evaluation metric and deeply involved with user perception and expectation, quantitative and comparative research was difficult because the QoE study is still in its infancy. At present, after tremendous devoted efforts have contributed to this research area, a shape of the QoE management architecture has become clear. Moreover, not only for research but also for business, video streaming services are expected as a promising Internet service incorporating QoE. This paper reviews the present state of QoE studies with the above background and describes the future prospect of QoE. Firstly, the historical aspects of QoE is reviewed starting with QoS (Quality of Service). Secondly, a QoE management architecture is proposed in this paper, which consists of QoE measurement, QoE assessment, QoS-QoE mapping, QoE modeling, and QoE adaptation. Thirdly, QoE studies related with video streaming services are introduced, and finally individual QoE and physiology-based QoE measurement methodologies are explained as future prospect in the field of QoE studies. key words: QoE, QoS, video streaming, user experience, personalization, physiology
随着宽带互联网和高性能设备的普及，各种服务随时随地都可以使用。因此，服务质量和体验质量(quality of Experience, QoE)作为一种从用户角度出发的评价指标得到了重视。由于质量质量是一种主观评价指标，与用户感知和期望密切相关，因此质量质量研究尚处于起步阶段，难以进行定量和比较研究。目前，在这一研究领域进行了大量的研究之后，QoE管理体系结构已经初具雏形。此外，视频流媒体服务不仅在研究领域，而且在商业领域也被认为是具有QoE潜力的互联网服务。本文在此背景下对质量质量评价的研究现状进行了综述，并对质量质量评价的未来前景进行了展望。首先，从QoS(服务质量)开始，回顾了QoE的历史方面。其次，提出了质量质量质量管理体系结构，包括质量质量质量度量、质量质量质量评估、质量质量质量-质量质量质量映射、质量质量质量建模和质量质量质量适应。第三，介绍了与视频流媒体服务相关的QoE研究，最后阐述了个体QoE和基于生理的QoE测量方法是QoE研究领域的未来前景。关键词:QoE, QoS，视频流，用户体验，个性化，生理学

In wireless links between ground stations and UAVs (Unmanned Aerial Vehicles), wireless signals may be attenuated by obstructions such as buildings. A three-dimensional RSS (Received Signal Strength) map (3D-RSS map), which represents a set of RSSs at various reception points in a three-dimensional area, is a promising geographical database that can be used to design reliable ground-to-air wireless links. The construction of a 3D-RSS map requires higher computational complexity, especially for a large 3D area. In order to sequentially estimate a 3D-RSS map from partial observations of RSS values in the 3D area, we propose a graph Laplacian-based sequential smooth estimator. In the proposed estimator, the 3D area is divided into voxels, and a UAV observes the RSS values at the voxels along a predetermined path. By considering the voxels as vertices in an undirected graph, a measurement graph is dynamically constructed using vertices from which recent observations were obtained and their neighboring vertices, and the 3D-RSS map is sequentially estimated by performing graph Laplacian regularized least square estimation. key words: unmanned aerial vehicle, received signal strength, graph Laplacian, least square estimation, sequential estimation
