In this paper we examine a number of solutions used in developing multimedia guiding systems for travelers. We pay particular attention to existing mobile audioguide systems and the capabilities they provide for tour creators. The major contribution of this work is to propose a model that would be appropriate for better tour recommendation and playback automation of outdoor travel tours with using...
Multimedia clips, such as lecture recordings and screencasts, are increasingly used in both formal and informal learning contexts, such as flipped classroom, blended learning, MOOCs and mobile learning. In order to create effective educational multimedia applications, it is increasingly important to understand the factors contributing to the learning performance and learner experience. This paper...
The behavior that people change their cell phones is very important for phone manufactures and mobile operators to make commercial plans and competing strategies to attain maximum benefit. In this paper, we aim to evaluate four existing prediction models in phone changing events, based on user behavior data collected from one telecommunication operator. First we adopt the feature extraction algorithms...
In this paper we propose the playback system for mashup based on mobile device in a sporting game. We designed the user experience for mobile environment: it was implemented so that a viewer can see the event segment video and the mashup information such as the additional information associated with it in the sporting game. Besides, it was also developed that a viewer can watch the main broadcasting...
This paper discusses the trends of technology in education and comparison between three types of technology: Augmented Reality (AR), Virtual Learning Environment (VLE) and Mobile Learning (ML). This paper aims to encourage educators and learners to incorporate the technologies in the teaching and learning process. The integration of these technologies in the teaching and learning process is able to...
Mobile devices create learning opportunities to which you cannot remain indifferent. If you combine these capabilities to specific needs of students and teachers, you will be on the path towards academic success. It was in this context that Letrinhas arose, an information system aimed at improving students' reading literacy developed by the Polytechnic Institute of Tomar (IPT) in response to a challenge...
In this paper we present the studies and research conducted within the eMadrid project, funded by the Regional Government of Comunidad Autónoma de Madrid. In particular, we focus on those works dealing with two research lines: ubiquitous and mobile learning; adaptation, adaptability and accessibility.
People increasingly use their mobile phones and mobile data to access different media types, including video. Due to mobile phone limitations, but also due to the scarce bandwidth on mobile networks, video content is often adapted to fit with these requirements by reducing its quality. In this study we look into how the user preference for a certain multimedia content (e.g. video, audio, text and...
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 development of HDR imaging is seen as an important step towards improving the visual quality of experience (QoE) of the end user in many applications. In practice, Tone-mapping operators (TMOs) provide a useful means for converting a high dynamic range (HDR) image to a low dynamic range (LDR) image in order to achieve better visualization on standard displays. Although mobile devices are becoming...
Quality of Experience (QoE) has become an increasing topic of research with the proliferation of multimedia services on mobile devices. Previous research studies have focused on proposing objective video quality assessment (VQA) metrics, and evaluating them on generic video content databases that consist mainly of natural clips such as news, sports and movies. This paper investigates the accuracy...
In the past few years, mobile devices quickly gained high popularity in our daily life. Designed for ultra-mobility, these small yet powerful devices are fundamentally distinct from traditional computer systems (e.g., PCs and servers) - from the internal hardware architecture and software stack, to application behaviors. Storage, the slowest component in the I/O stack, plays an important role in mobile...
Due to the ever growing mobile broadband data traffic over the cellular networks, the small cell deployment is seen as a promising solution for the network operators to increase their network capacity at low cost. This in turn would lead to an increase number of handovers (HOs) for the mobile users, which could affect the device power consumption. In this context, this paper investigates the impact...
This is a multiphase study which aims to investigate how to provide learners with an method to acquire classical Chinese through integrating mobile technology with the flipped classroom approach. Currently, in the first phase of study, the researcher adopts informant design through questionnaire survey to understand students' and instructors' perceptions of using mobile learning devices for classical...
Mobile technology in learning process is quite demanding, nowadays. It has a huge potential as a learning tool and also can be used as distance learning environment. Towards this, many mobile learning application tools have been developed in order to meet the user demand. This generates the idea of developing Arabic grammar learning tool due to most of people especially UiTM Kedah students have lack...
Mobile devices have become important companions to most people, and are increasingly used for work and/or entertainment, most of the time consuming multimedia content. Diverse Quality of Service (QoS) metrics help estimate the enduser perceived quality or Quality of Experience (QoE) of the multimedia delivery to these mobile devices. However, energy consumption and device battery lifetime are also...
Mobile application has existed due to the advancement in mobile technology. It takes place in knowledge dissemination and learning by utilizing the portability and anywhere anytime access of mobile phone. The substance of mobile storytelling reaches from folktale, personal information, public history and historical event. However, from the studies conducted, a methodology for developing framework...
Given the global spread of mobile platforms, such as iOS and Android, it is relevant to consider the potential of these devices in teaching and learning. Our exploratory research was designed to evaluate the possibility of using common ebook formats to create gamebooks (gamified books) that are effective in teaching and learning. After analyzing the features available in many free or open tools, we...
Developing mobile multimedia cloud services over heterogeneous wireless networks poses a challenge for service continuity. The degraded link quality and connection losses are likely to happen and these may affect service execution times and service availability in mobile cloud computing scenarios. To improve handoff quality and minimize utilized bandwidth, we propose a self-adaption handoff scheme...
Nowadays, due to the explosive growth of mobile devices, social networks and multimedia contents sharing systems have become increasingly popular. However, the characteristics of mobile devices and tags make it difficult to perform an accurate tag-based multimedia retrieval. In this paper, we propose a novel tag recommendation system for multimedia retrieval based on the user trust model which takes...
