“…User studies are the first and basic step in the modeling of the QoE of any service. The factors affecting the QoE can be divided into systemic, user and contextual [40]. Most of the studies in this field focused on the impact of network latency and loss of package on the QoE [41][42][43][44][45][46][47][48].…”

“…Most of the studies in this field focused on the impact of network latency and loss of package on the QoE [41][42][43][44][45][46][47][48]. In general, the results show that cloud gaming is highly sensitive to network latency and that package losses of less than 1% caused significant degradation of the players' QoE [40], as confirmed by a commercial platform study [49], but also by a study of an open-source platform GamingAnywhere [50]. The research clearly recognized the sensitivity of this service to network degradation and it is therefore necessary to dynamically adjust the service to network condition on the basis of optimization of algorithms in order to avoid congestion that causes latency and package losses.…”

The use of digital games in education has been the subject of research for many years and their usefulness has been confirmed by many studies and research projects. Standardized tests, such as PISA test, show that respondents achieved better reading, math and physics results if they used the computer more for gaming-related activities. It has been proven that the application of video games in education increases student motivation, improves several types of key skillssocial and intellectual skills, reflexes and concentration. Nevertheless, there are several challenges associated with the application of video games in schools and they can be categorized as technical (network and end device limitations), competency (teachers' knowledge in the area), qualitative (lack of educational games of high quality), and financial (high cost of purchasing games and equipment). The novel architecture for delivery of gaming content commonly referred to as "cloud gaming" has the potential to solve most of the present challenges of using games in education. A well-designed cloud gaming platform would enable seamless and simple usage for both students and teachers. While solving most of the present problems, cloud gaming introduces a set of new research challenges which will be discussed in this section.

“…The client is responsible for decoding the video and capturing the player's commands. Two network-level factors are critical: the bandwidth required by the video stream (influencing image quality and frame rate) [58], and the Round-Trip Time (RTT) (influencing the game's responsiveness to input commands) [13,14]. For online games, the throughput is much less important when compared to the RTT.…”

Whereas some application domains show a certain consensus on the role of system factors, human factors, and context factors, QoE management of multimedia systems and services is still faced with the challenge of identifying the key QoE influence factors. In this chapter, we focus on the potential of enhancing QoE management mechanisms by exploiting valuable context information.To get a good grip on the basics we first discuss a general framework for context monitoring and define context information, including technical, usage, social, economic, temporal, and physical factors. We then iterate the opportunities and challenges in involving context in QoE monitoring solutions, as context may be, e.g., hard to ascertain or very situational.

“…As reported in [5,[14][15][16], packet loss and delay have a significant impact on cloud gaming QoE. Basically, network congestion results in network delay jitter and when queue size is exceeded, packet loss occurs.…”

“…For Real-time Strategy (RTS) games, the process of constructing buildings or moving troops towards a battlefield is unaffected by latency as high as 1000 ms [15]. However, First Person Shooter (FPS) games, where users are shooting at a moving target tend to be more sensitive to latency with delays of over 100 ms seen as unacceptable [19].…”

Abstract. Cloud gaming is an emerging technology that combines cloud computing with computer games. Compared to traditional gaming, its core advantages include ease of development/deployment for developers, and lower technology costs for users given the potential to play on thin client devices. In this chapter, we firstly describe the approach, and then focus on the impact of latency, known as lag, on Quality of Experience, for so-called First Person Shooter games. We outline our approach to lag compensation whereby we equalize within reason the up and downlink delays in real-time for all players. We describe the testbed in detail, the open source Gaming Anywhere platform, the use of NTP to synchronise time, the network emulator and the role of the centralized log server. We then present results that firstly validate the mechanism and also use small scale and preliminary subjective tests to assess and prove its performance. We conclude the chapter by outlining ongoing and future work.
