Abstract :"Quality of experience (QoE) is a measure of the customer's experience with a service. In an online gaming scenario, players expect the experience to be realistic, continuous and precise. It is important to know not just the end user's experience but also the probable cause of the experience, good or bad. Understanding the cause is essential for improving the game design via a feedback loop, which in turn con- tributes towards game longevity. We begin by focussing on two broad categories of the QoE measurement tech- niques for gaming scenario, subjective and objective measurement. We then study two frameworks, One-Click[4] and Perceptual View Inconsistency[5] from the perspec- tive of the scenarios in which they can be applied, their ability and more importantly, their inability to measure certain aspects of end user experience, and the diculties encountered while applying these techniques. Subsequently, we try to propose a sim- ple scheme in which both of these techniques can be used to complement each other in a real life scenario, and get the best out of both."

Abstract: "Cloud gaming provides game-on-demand (GoD) services over the Internet cloud. The goal is to achieve faster response time and higher QoS. The video game is rendered remotely on the game cloud and decoded on thin client devices such as tablet computer or smartphone. We design a game cloud with a virtualized cluster of CPU/GPU servers at USC GamePipe Laboratory. We enable interactive gaming by taking full advantage of the cloud and local resources for high quality of experience (QoE) gaming. We report preliminary performance results on the game latency and frame rate. We find 109 ~ 131 ms latency in using the game cloud, which is 14% ~ 38% lower than 200 ms latency experienced on a thin local computer. Moreover, the frame rate from the cloud is 25% ~ 35% higher than that of using a client computer alone. Base on these findings, we anticipate game cloud to have a performance gain or QoS improvement of 14% ~ 38% over video gaming on a thin client device such as a smartphone or a tablet computer."

"Digital technology empowers one to access vast amounts of on-line data. From a learning perspective, however, it is difficult to access meaningful on-site information within a given context. The Hypercontextualized Game (HCG) design model interweaves on-site resources, translated as content, and the digital game. As a local game design process, HCG builds on the resources available on-site (context) and transfers them beyond their origin (hyper). A successful example is the HCG stories in LieksaMyst, an application developed for the Pielinen Museum, in which the player is guided through a series of activities by a virtual host from the historic past. It took three years of extensive work and research for the LieksaMyst HCG stories to mature from brainstorming concepts to a fully-fledged museum service. Curators, educational technology experts and a total of 476 visitors (from 6 to 77 years old) contributed to the design process. The analysis of the context and feedback from the visitors enabled us to choose media, content and activities suitable to the Pielinen Museum. Our findings indicate that quality time, sincere reflection and communication between local experts and potential players, are indispensable when designing a HCG based game. The analysis benefits researchers and practitioners who are interested in the ways in which a game can bridge the gap between people and relevant on-site information"
