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."

Abstract: "the boom of Cloud Computing services in the recent years has created new opportunities and removed many of the limitations that are typically tied to software deployed on the Internet. It has been shown that the development of online games can benefit from the integration of Cloud services into their design in order to solve many of the problems that plague their development and maintenance. In this paper, we first discuss the current designs of online gaming architectures and present their limits. The solutions offered by using Cloud services in respect to these video games are then explored and the new problems that arise from this combination are addressed. We also present a case study by deploying an online First Person Shooter multiplayer video game on currently available Cloud infrastructures (using Amazon Elastic Compute Cloud) and detailing our architecture specifically designed for this purpose. We show that, where once entering the market of online games was solely affordable by big companies due to the high infrastructure costs, a single person could now create and deploy an online game."

Abstract: "Cloud gaming now makes any computer game playable on a thin client without the previous worries and frustrations about the hardware requirements. It frees players from the need to frequently upgrade their computers as they can now play games that are hosted on remote servers with a broadband Internet connection and a thin client. However, cloud games are intrinsically more susceptible to latency than online games because game graphics are rendered on cloud servers and thin clients do not possess game state information that is required by delay compensation techniques. In this paper, we investigate how the response latency in cloud gaming would affect users' experience and how the impact of latency on players' experience varies among different games. We show that not all games are equally friendly to cloud gaming. That is, the same degree of latency may have very different impacts on a game's quality of experience depending on the game's real-time strictness. We thus develop a model that can predict a game's real-time strictness based on the rate of players' inputs and the game screen dynamics. The model can be used to simultaneously enhance players' gaming and optimize the operation cost of data centers."

Abstract: "Obesity has become an outstanding public health issue in most countries around the world. Many attempts have been made to address this issue that ranges from taking medication to doing exercise to follow- ing a diet plan to playing games. Few approaches combine exercise and game to engage the obese people in playing fun-based games or pur- poseful games, also known as serious games, while monitoring their bio- signals. However, existing work hardly provides a configurable, scalable and context-aware serious game framework that can be used as a sup- port for obesity treatment. In this paper, we take an attempt to propose such a framework. The proposed framework facilitates bio-signal monitor- ing based on body sensor network, context-awareness based on perva- sive sensors, and on-the-spot activity recommendation based on current game-playing context. It uses the cloud computing platform as infrastruc- tural support that ensures the scalability of the framework. In order to demonstrate the suitability of the proposed framework, we developed a sample serious game; deploy it over a cloud platform; and experiment with it by capturing some psycho-physical data while the obese are en- gaged in game-play. We observed that the obese people were very much engaged in game-play and they had positive experience using the system"

Abstract: "To improve musical auditory habilitation for children post cochlear im- plantation, we developed MOGAT: MObile Games with Au- ditory Training. The system includes three musical games built with o-the-shelf mobile devices to train their pitch perception and intonation skills respectively, and a cloud- based web service which allows music therapists to monitor and design individual training for children. The design of the games and web service was informed by a pilot survey (N=60 children). To ensure widespread use with low-cost mobile devices, we minimized the computation load while retaining highly accurate audio analysis. A 6-week user study (N=15 children) showed that the music habilitation with MOGAT was intuitive, enjoyable and motivating. It has improved most children's pitch discrimination and production, and several children's improvement was statistically signicant (p < 0:05)."
