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.

该研究项目旨在识别与移动在线游戏相关的质量维度的识别，主观测量和工具预测。这个想法是要描述流动机游戏的质量，其听觉和视觉输出是实时通过基于IP的通道传输的，作为多维空间中的感知事件，并在此基础上定义有效可靠的质量预测模型。这样的模型不仅估计了总体质量，还诊断出质量降解的原因和相关感知影响。在先前在固定环境中与游戏交互质量的感知维度的工作之后，第一步是确定与移动游戏相关的感知质量维度（即，在具有有限的计算资源和受限网络连接性的手持设备上与游戏的交互作用）。这是通过使用改编的开源云游戏测试床通过多维心理测量学分析来实现的，该测试床可以通过人类测试参与者经历有损耗的传输渠道发送压缩音频和视频数据的典型质量降解。为了量化已确定的维度，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，并有效地测量所有维度以及整体质量。该测试方法用于收集测试床参数的数据库和相应的主观评分。该数据库构成了得出个人感知维度的质量估计的基础，并在第二步中 - 整体游戏质量的第二步。最终使用在进一步研究中收集的数据验证了派生模型。
