“…Based on their study, [11] suggest that mobile cloud computing be used to present multimedia content based on the existing limitations of mobile devices, such as space storage, computing power, and broadband strength, in support of an adaptive interface. Cloud computing can be visualised as a new paradigm for mobile applications whereby the processing and storage of data could be transferred from the mobile device to a powerful computing platform centred on a "cloud".…”

The focus of this study is to improve the display platform for the State of Terengganu Virtual Museum System (muziummaya.terengganu.gov.my user requirements analysis, interface design, and usability evaluation. The result of this research is the design of a multi-dimensional user interaction context that meets the display requirements and navigation information for mobile devices. Keywords: user interaction, information presentation, designing mobile interface, virtual museumCopyright © 2016 Institute of Advanced Engineering and Science. All rights reserved. IntroductionThe presentation of information should be displayed via a multi-dimensional user interaction context, which is not only limited to the computer screen but should also include small screen displays such as the ones on mobile devices. However, the challenges in designing a user interface include cognitive load and information presentation. Cognitive load issues occur when the user is forced to simultaneously divide his or her attention between certain tasks on a small display. Besides that, an excess of information presentation at any one time could result in information overload. Interface design for mobile devices should assist users to access relevant information without having to rely on their memory and strong visual attention on said interface. Zhang et al [1] stated that the main issue that interface designers face is how to present a lot of information on a small screen for effective and simple navigation, so as not to tax user memory load. The work of [2] showed users experienced a change in emotions when they visited the virtual museum as a result of information overload on the small screen of mobile devices. Users need a mobile application that can access and display the gallery panorama including the artifact hotspots in the gallery. Wook T [3] also suggests that the gallery display technique (floorplan and panorama) be used in the existing virtual museum, as it can optimise the screen space of mobile devices, which have smaller screens than computers, and thus, access and display artifact information in 3D.Each user has different personalities and attitudes when surfing for information on the Internet. This proves that user behaviour is important factors, which, besides information content display (gallery, artifact, and information), also involves interaction. The user interaction context via mobile devices calls for meticulous design and entails different requirements than desktop computing displays [4]. The design of information on mobile device displays must be more attractive to engage users to search for information and to increase the fun factor. Since information searching in the virtual museum environment allows for 360° exploration and 3D image display, emotions that can induce "sensitive memories" would also be indirectly

“…During this process, the end user evaluates cognitive skills that are used for modeling knowledge and understanding in a given field [25]. The experiments done in the proposed framework for mobile adaptive multimedia delivery [25], have confirmed the existence of different user experience while using the mobile cloud computing environment in practice. That leads to the next important criterion for modeling of adaptive multimedia content, the context-aware influence of network parameters during the process of delivery of multimedia content [25].…”

Cloud computing consists of hardware and software resources, available on the Internet as a set of services for users. This technology aims to provide stable, reliable and encapsulated dynamic information and communication environment for end users to be able to simultaneously access shared resources that are available anywhere and at any time. The major benefit of cloud computing is used to improve the perception of quality for the client requests. Commonly in the communications industry, the term Quality of Experience (QoE) is used as a measure for the user perception of service from the user's point of view. In this research, we propose a classification of cloud-based services based on objective and subjective characteristics for perception of quality. The main contribution in this paper is a novel approach based on Bayesian modeling for efficient assessment of QoE perception for cloud-based services considering the level of interactivity, service complexity, usage domain, and multimedia-intensity.

Reducing the total power consumption and network delay are among the most interesting issues facing large-scale Mobile Cloud Computing (MCC) systems and their ability to satisfy the Service Level Agreement (SLA). Such systems utilize cloud computing infrastructure to support offloading some of user's computationally heavy tasks to the cloud's datacenters. However, the delay incurred by such offloading process lead the use of servers (called cloudlets) placed in the physical proximity of the users, creating what is known as Mobile Edge Computing (MEC). The cloudlet-based infrastructure has its challenges such as the limited capabilities of the cloudlet system (in terms of the ability to serve different request types from users in vast geographical regions). To cover the users demand for different types of services and in vast geographical regions, cloudlets cooperate among each other by passing user requests from one cloudlet to another. This cooperation affects both power consumption and delay. In this work, we present a mixed integer linear programming (MILP) optimization model for MEC systems with these two issues in mind. Specifically, we consider two types of cloudlets: local cloudlets and global cloudlets, which have higher capabilities. A user connects to a local cloudlet and sends all of its traffics to it. If the local cloudlet cannot serve the desired request, then the request is moved to another local cloudlet. If no local cloudlet can serve the request, then it is moved to a global cloudlet which can serve all service types. The process of routing requests through the hierarchical network of cloudlets increases power consumption and delay. Our model minimizes power consumption while incurring an acceptable amount of delay. We evaluate it under several realistic scenarios to show that it can indeed be used for power optimization of large-scale MEC systems without violating delay constraints.
