This research project aims at the identification, subjective measurement and instrumental prediction of quality dimensions associated with mobile online gaming. The idea is to describe the quality of a streamed mobile game, with its audible and visual output being transmitted over an IP-based channel in real time, as a perceptual event in a multidimensional space, and to define a valid and reliable quality prediction model on this basis. Such a model estimates not only overall quality, but also diagnoses causes and related perceptual effects of quality degradations. Following prior work on perceptual dimensions of the quality of an interaction with a game in a stationary setting, the first step is to identify perceptual quality dimensions associated with mobile gaming (i.e. the interaction with a game on a handheld device with limited computational resources and constrained network connectivity). This is achieved via multidimensional psychometric analyses using an adapted open-source cloud gaming test bed, which allows typical quality degradations of sending compressed audio- and video data over a lossy transmission channel to be experienced by human test participants. In order to quantify the identified dimensions, a new subjective test method will be established which consists of a structured interaction test and efficiently measures all dimensions as well as the overall quality. This test method is used to collect databases of test bed parameters and corresponding subjective ratings. The databases form the basis for deriving quality estimations of individual perceptual dimensions and - in a second step - of overall gaming quality. The derived model is finally validated using data gathered in a further study.

本研究项目旨在识别、主观测量和工具预测与移动网络游戏相关的质量维度。我们的理念是将流媒体手机游戏的质量描述为多维空间中的感知事件，即通过基于ip的渠道实时传输声音和视觉输出，并在此基础上定义有效且可靠的质量预测模型。这样的模型不仅估计了整体质量，而且还诊断了质量退化的原因和相关的感知效应。继之前关于在固定环境中与游戏互动质量的感知维度的工作之后，第一步是确定与手机游戏相关的感知质量维度（即在计算资源有限和网络连接受限的手持设备上与游戏的互动）。这是通过使用改进的开源云游戏测试台进行多维心理测量分析来实现的，该测试台允许通过有损传输通道发送压缩音频和视频数据的典型质量下降，以供人类测试参与者体验。为了量化所识别的维度，将建立一种新的主观测试方法，该方法由结构化的交互测试组成，有效地测量所有维度和整体质量。该测试方法用于收集试验台参数数据库和相应的主观评分。这些数据库构成了对个人感知维度进行质量评估的基础，并在第二步中对整体游戏质量进行评估。最后利用进一步研究中收集的数据验证了推导出的模型。
