“…From this perspective, it is important to highlight the findings of Kaikkonen et al in [1] who conclude that the results obtained in the artificial, laboratory environments may suggest that a specific service needs higher QoS demands than it is actually the case. Therefore, it is worth conducting subjective tests of QoE in real-life environments and in situations that reflect everyday service usage scenarios [3].…”

“…This implies the assessment after the game is put into use. Examples of assessment are presented in [4]. Authors in [4] demonstrated the quality of service provided by the usability studies for egames and focus in these assessments was on the resources available for users regarding network and service providers.…”

“…Inspired by the revolution towards esocieties and elife, digital games play a significant role in individuals' lives. Recently, wide range of research in the digital games field described diverse aspects regarding development platforms, hardware usability, and usability of digital games after they are put into use [4]. However, the research regarding digital mobile games assessment lacks the clear and identified quality assessment justifiable measures [4].…”

Due to evolution of digital games towards mobile platforms, a large exposure to mobile games is nowadays recorded. This is because of the availability of the cell phone with individuals anytime anywhere. Hence, a vital role of game quality assessment is raised. This is for the purpose of serving as a guide for developing healthy games. Accordingly, the mobile games would help in boosting the educational entertainment, healthy diets control, and behavioral sciences studies and research. This paper presents quality assurance and quality models for ISO based educational game. In this paper, an ISO quality model is presented and quality application behavioral impact measures are justified to evaluate the development quality of Miftah Alfasaha game. The quality model and proposed quality assessment plan are tested through a CodePro Analytix tool and six sigma evaluations.

“…However, research has also shown that assessing quality in more realistic environments can impact users' quality perception and overall QoE [6], [33], [42]. Therefore, in order to better understand QoE, Van den Broeck et al [43] argue that the everyday-life context should be integrated in subjective video quality experiments.…”

Abstract-HTTP Adaptive Streaming facilitates video streaming to mobile devices connected through heterogeneous networks without the need for a dedicated streaming infrastructure. By splitting different encoded versions of the same video into small segments, clients can continuously decide which segments to download based on available network resources and device characteristics. These encoded versions can, for example, differ in terms of bitrate and spatial or temporal resolution. However, as a result of dynamically selecting video segments, perceived video quality can fluctuate during playback which will impact end-users' Quality of Experience. Subjective studies have already been conducted to assess the influence of video delivery using HTTP Adaptive Streaming to mobile devices. Nevertheless, existing studies are limited to the evaluation of short video sequences in controlled environments. Research has already shown that video duration and assessment environment influence quality perception. Therefore, in this article, we go beyond the traditional ways for subjective quality evaluation by conducting novel experiments on tablet devices in more ecologically valid testing environments using longer duration video sequences. As such, we want to mimic realistic viewing behaviour as much as possible. Our results show that both video content and the range of quality switches significantly influence end-users' rating behaviour. In general, quality level switches are only perceived in high motion sequences or in case switching occurs between high and low quality video segments. Moreover, we also found that video stallings should be avoided during playback at all times.Index Terms-Quality of Experience (QoE), Subjective video quality assessment, HTTP adaptive streaming, Mobile video, Tablet devices.
