Using service-based content adaptation platform to enhance mobile user experience

Internet access using mobile handheld devices has surpassed that of fixed Internet, but most web pages are designed for desktop browsers. Mobile devices have resource limitations. Consequently, web pages designed for desktop browsing cannot be well displayed on mobile devices. Thus, dynamically transforming web contents designed for desktops into contents which can be displayed in a mobile device is an important task. Various approaches of content adaptation have been proposed to achieve this goal, but no single content adaptation strategy has been found to be effective. On the other hand, e-learning contents have grown manifold over years. In this paper, we provide a framework for an e-learning content adaptation system that can be used with desktops and mobile devices seamlessly. We combine multiple content adaptation strategies to make e-learning contents appropriate for mobile devices. Among the various content adaptation strategies, the segmentation algorithm plays the most important role. Our experiments demonstrate that the proposed scheme can be successfully utilized for content adaptation in mobile and handheld devices.

The mobile environment presents numerous challenges to users and developers alike. Ideally, mobile content should be designed to enhance a user's experience rather than simply serve up the same content originally designed for other platforms. This chapter presents a study of techniques for “content adaptation”, the process of reformatting content and displaying it optimized for a mobile device. Adaptation techniques consist of a varied number of mechanisms by which content is adapted into a format more “friendly” to mobile devices. The idea of “friendly” can range from simple accessibility requirements to a dynamic redesign. Included in this discussion is a summary of the advantages and disadvantages of current techniques. Examples of different techniques are presented and illustrated along with the system framework necessary to implement them.

An empirical study on user experience evaluation of VR interface in digital museums

In this paper, the authors present their proposal for adaptation of educational contents of learning objects to a particular mobile device and a specific learner. Content adaptation in mobile learning objects implies user adaptation and device adaptation, and requires additional metadata categories in comparison with SCORM 2004. This learning object content model, ALMA (A Learning content Model Adaptation), inherits from the SCORM standard a subset of metadata categories, and extends it with three top level metadata categories for content adaptation, i.e., Knowledge, Use, and Mobile Device Requirements (Castillo & Ayala, 2008). For user adaptation, the authors developed NORIKO (NOn-monotonic Reasoning for Intelligent Knowledge awareness and recommendations On the move), a belief system based on DLV, a programming system based on Answer Set Programming paradigm. For device adaptation the authors designed CARIME (Content Adapter of Resources In Mobile learning Environments), which uses transcoding and transrating to adapt media content to suit the device characteristics.

The latest growth of mobile technology has resulted in more users accessing network services via mobile devices, such as tablets or smartphones. Personalized look and content becomes more important. Mobile devices have different properties than desktop computers. Mobile devices do not have a large screen, convenient input-output devices, and have limited computing capabilities. Content adaptation is a common definition used for adaptation or customization of content transferred from the server via the HTTP protocol to the client. The research method is to adjust the content which will be transferred to the user based on the device resources i.e. the battery on the client side so that higher service quality will be achieved. In this study, researchers will conduct the development of content adaptation methods that consider the condition of battery resources on the devices. Battery resource estimation is done to determine the current condition of existing battery in accessing device. The appropriate content determination mechanism will be based on the value generated from the estimated resource of the battery on the device that has been done.

An end-use’s experience of any software is typically influenced by the interface presented by the application to the user. For Mixed Reality Environments such as Augmented and Virtual Reality, the user interface is highly visual, and a poor interface can significantly degrade the user experience. Adequate attention is required when designing or creating interfaces and user experience within Mixed Reality Environments as traditional interface design goals and specifications often need to be adjusted. Furthermore, for mixed reality environments on Mobile devices there are additional interface constraints and considerations that would considerably improve the user experience when properly addressed. This research paper discusses the evolution(s) of user interface(s) and user experience of Augmented and Virtual Reality applications on Mobile devices and contributes a framework for improving user interfaces and experience when using Mixed Reality Environments.

With the continuous progress and development of technology people's demand for interactive experience is increasing, the interactive concept has become an important trend in today's design field. It refers to an approach to designing and developing products, services or systems that emphasises the interaction between the user and the product, system or environment. It considers the user not only as a user of the product, but also as an active participant in the design process. It mainly includes interaction methods, feedback mechanisms, personalisation and other aspects to reflect the interactive concept. Emotional design is a design concept belonging to a deeper level of interaction design, which is the integration of design concepts with emotional aspects with interaction design to meet the emotional needs of users. Storylines, symbols and metaphors are used to trigger an emotional response from the user. Interaction design aims to improve user satisfaction and experience by designing interfaces that are easy to use, intuitive and enjoyable. It is not just about meeting the functional needs of the user, but also about its impact on human emotion and pleasure. And interaction design is the practice of defining and constructing interactive experiences is a new design approach based on the development of new media technology and user experience derived from the aspects of design, psychology, computer science and other disciplines, in order to create an experience that meets the needs of the user, the pursuit of fun and novelty.The aim of this paper is whether the specific application and methods of interaction design on human emotion and pleasure under the interactive concept enhances and improves the user's emotional experience. It is hoped that through this study, the use of interaction design on human emotion and pleasure under the concept of interaction can be enriched to enhance the value of user experience and product value. Moreover, on the basis of the interactive concept, the close integration of interactive design and human emotion will make the public more aware of the importance and necessity of interactive design for human emotion and pleasure.This paper explores the cases of human-computer interaction, interactive games, interactive advertisements, and interactive videos through specific case studies, functional analysis, and case studies, which can be combined with cases in different fields to analyse the importance of interactive design on human emotions. The purpose of this study is to investigate the impact of interactive design on human emotion and pleasure based on the concept of interactivity. Better interaction design can enhance users' emotional experience and pleasure, help users deal with negative emotions, increase users' satisfaction with products, enhance users' engagement and the value of products or services, and promote innovation of products or services. An in-depth study of the use of interactive design on human emotion and pleasure, and maintaining products through interactive concepts and emotional design is important for improving product functionality and enhancing user experience.

In this research article, we present the initial results of our case study on improving user experience (UX) in a fully online enrolment process at an e-learning university, the Universitat Oberta de Catalunya (UOC). Our main conclusion is that an omnichannel approach is necessary for improving prospective students’ UX. To obtain our results, we made use of three different data sources, which allowed us to map a current and future customer journey. These sources were: (1) quantitative data on the main stages in the process at which prospective students drop out; (2) field diaries compiled by prospective students over the course of the enrolment process and a co-creation workshop with the same prospective students; and (3) the UOC’s perspective, gathered from workshops and interviews with University staff responsible for the enrolment process. Comparing the current journey with the ideal journey, we will demonstrate that significant improvements can be made to prospective students’ UX in online enrolment via an omnichannel approach. We discovered a need for improved channel coordination (e.g. information transfer between channels), greater availability and a wider range of channels (inbound and outbound, telephone vs. chatbot), personalization and adaptation of channel content according to the stage prospective students have reached in the process, and the ability to choose the channel that best meets their needs (chatbot for commonly asked questions vs. real people for more complex or specific queries). In view of our results, we would especially highlight technological and organizational changes as the next steps to take.

With the evolution of mobile devices and networks, and the growing trend of mobile Internet access, rich multi-player gaming using mobile devices, similar to PC-based Internet games, has tremendous potential and interest. However, the current client-server architecture for PC-based Internet games, where most of the storage and computational burden of the game lies with the client device, does not work with mobile devices, constraining mobile gaming to either downloadable, single player games, or very light non-interactive versions of the rich multi-player Internet games. In this article, we study a cloud server based mobile gaming approach, termed Cloud Mobile Gaming (CMG), where the burden of executing the gaming engine is put on cloud servers, and the mobile devices just communicate the users' gaming commands to the servers. We analyze the factors affecting the Quality of user Experience (QoE) using the CMG approach, including the game genres, video settings, the conditions of server and client, and the conditions of the wireless network. A Mobile Gaming User Experience (MGUE) model is developed and validated through controlled subjective testing. We also develop a prototype for in-service measuring MGUE, and then use it to characterize user experience achievable using the CMG approach in a mobile cellular network. The MGUE model developed and validated in this article will be helpful for researchers and service providers to develop and assess the performance of future cloud mobile gaming techniques and services.

With the rapid advancement of the digital era, people's lifestyles and consumption patterns have undergone significant changes. Instead of making phone calls for food delivery, consumers now have the convenience of using mobile devices like smartphones or tablets to access online food delivery platforms. Through these platforms, customers can effortlessly select their preferred dishes and restaurants, facilitating quick and seamless food delivery transactions. Examining consumers' perceptions and viewpoints concerning the user interface and functionalities of food delivery platforms on mobile devices holds significant importance for e-commerce operators in the present scenario. The questionnaires in this study were devised to gain insights into consumers' perspectives on the user experience and functionalities while using food delivery platforms. The research findings revealed that the respondents considered "providing diverse payment methods" and "offering promotions" as the two most essential features of a food delivery platform. Moreover, consumers highly value the platform's ability to provide a flexible refund mechanism.

The applications of Augmented Reality (AR) in such mobile devices as phones and pads can enhance the users' experiences both in virtual and real world.

It is a combination of virtual and physical reality, which builds virtual worlds with changeable scenes, brings authentic user experience and records process for analyzing and evaluation. Players are trained in a closed environment, which is composed of projectors, multimedia devices and physical scene. The application of mobile AR device guides the entire training process, and users make effective interaction with mobile devices to start and finish training mission. In the proposed system five innovative methods are implemented to improve interaction quality. An experiment case is devised with a series of tasks and conundrums for players, experimental results show that the MCTS can contribute more effective educations on team consciousness through the use of mobile AR technology and multimodal interaction to integrate virtual and real experience.

Mobile devices with limited resources are prevalent as they have a relatively low price. Providing a good user experience with limited resources has been a big challenge. This paper found that foreground applications are often unexpectedly interfered by background applications' memory activities. Improving user experience on resource-limited mobile devices calls for a strong collaboration between memory and process management. This paper proposes a framework, Ice, to optimize the user experience on resource-limited mobile devices. With Ice, processes that will cause frequent refaults in the background are identified and frozen accordingly. The frozen application will be thawed when memory condition allows. Evaluation of resource-limited mobile devices demonstrates that the user experience is effectively improved with Ice. Specifically, Ice boosts the frame rate by 1.57x on average over the state-of-the-art.

Energy conservation in battery powered mobile devices that perform wireless multimedia streaming has been a significant research problem since last decade. This is because these mobile devices consume a lot of power while receiving, decoding and ultimately, presenting the multimedia content. What makes things worse is the fact that battery technologies have not evolved enough to keep up with the rapid advancement of mobile devices. This survey examines solutions that have been proposed during the last few years, to improve the energy efficiency of wireless multimedia streaming in mobile hand-held devices. We categorize the research work according to different layers of the Internet protocol stack they utilize. Then, we again regroup these studies based on different traffic scheduling and multimedia content adaptation mechanisms. The traffic scheduling category contains those solutions that optimize the wireless receiving energy without changing the actual multimedia content. The second category on the other hand, specifically modifies the content, in order to reduce the energy consumed by the wireless receiver and to decode and view the content. We compare them and provide evidence of the fact that some of these tactics already exist in modern smaprtphones and provide energy savings with real measurements. In addition, we discuss some relevant literature on the complementary problem of energy-aware multimedia delivery from mobile devices and contrast with our target approaches for multimedia transmission to mobile devices.

Mobility devices are crucial in enhancing activities and participation for individuals with mobility disability, particularly among the rapidly expanding population of older adults worldwide. This paper explores patterns of mobility device use among a nationally representative cohort of community-dwelling older adults in the United States, using data from the National Health and Aging Trends Study (NHATS) waves 1–9 (2011–2019). Our descriptive analysis focuses on the characteristics of incident mobility device use, its influencing factors, and related user experiences, aligning with the NHATS late-life disability framework. Mobility devices were categorized into walking aids (WAs), wheeled and seated mobility devices (WSMDs), and mixed use of both. We identified 2,943 incidents of mobility device use among 2,591 participants, spanning 47,722 person-years in community settings, yielding an incidence rate of 61.7 per 1,000 person-years. Over half (51.3%) of mobility device use ended in 1 year, with WAs being the predominantly used (63.8%). About one-third (30.5%) of these incidents involved a change in device combinations, with a notable shift towards WSMDs and mixed use over time. We found that older adults using WSMDs or changing their device combinations were in a more vulnerable state, while those using mixed devices or changing their device combinations experienced poorer user experiences. This study advocates for the implementation of rental and recycling programs, the involvement of NGOs and professional associations, and the adoption of flexible policies responding to the dynamic patterns of mobility device use among community-dwelling older adults. It also recommends expanding services to better serve vulnerable subgroups.
