Social context is important to a variety of significant applications such as business intelligence, public security and epidemic. For example, companies can refine the advertisement strategy by targeting the influential people within the social group. Social context modelling and recognition is an emerging research area which aims to infer the information that characterizes multiple users such as...
Touch operation has already become a common technique, and will be adopted to most electrical appliances in the future. Therefore, we suppose that a user's touch operation will be one of important contexts for realizing the future context-aware system. Through observation of the user's touch operation, a system could estimate the user's emotion, skill, etc. In this demonstration, we exhibit our system...
Based on the technology acceptance model, the paper developed a conceptual model for mobile game adoption. A questionnaire was developed built upon previous studies. A survey was then conducted, which received 267 useful responses. The results suggested that users perceive mobile game differently with regard to experience and gender difference. It is suggested that the users who have more computer...
This paper reports and discusses the findings from the first phase of a research study concerning the use of mobile technologies for teaching and learning within 10 schools in Hong Kong. Implementation plans devised by the schools were evaluated by an extended framework for analyzing mobile learning with a view from teachers' perspective. Initial finding reveals that teachers could contrive limited...
The goals of South Africa's e-Education White paper is for every school learner in the country to be ICT capable by 2013 and for teachers to use information and communication technology (ICT) to enhance teaching and learning. Many initiatives have been undertaken to provide schools with computer labs and infrastructure in order to reach these goals, with varying degrees of success. In the meanwhile,...
In the pervasive system, it is important for its application to adapt to mobile devices. But most of pervasive systems are not quickly suitable for mobile device. In order to provide adaptive mobile services, the approach for self-adaptation is proposed in this paper. Firstly, context of mobile devices and its influence on pervasive application are analyzed and business rules based on this analysis...
The Internet is going mobile, and indications are that the mobile Internet will be ??bigger?? than the conventional Internet. Due to aspects such as user mobility, much more diverse use situations, and the form factor of mobile devices, context awareness is important on the mobile Internet. Focusing on geo-spatial context awareness, this talk covers research that aims to build infrastructure for mobile...
In mobile networks a service provider needs access to the user data for providing rich and context-aware service like locating the position of mobile user. Mobile assistant (MA) acts as a user data broker network element. Mobile assistant has a complete access to all static and dynamic user data. The purpose of Mobile assistant is to accept requests for user data, to determine user's context, to extract...
In recent years, with the rapid development of mobile computing technologies, a new learning style-mobile learning has exploded everywhere in our society, which is considered as an essential learning style in the future. This paper presents a mobile learning system taking into account learning context, which is also called contextual mobile learning. With the help of this system, we can learn just...
In this paper, we introduce an m-commerce security architecture; discuss how the communication takes place between user, mobile station (MS) and access point (AP). We use an new authenticated mechanism between user and MS. And we add Access Point in wireless net in order to avoid being attack and eavesdropping message. We analyze the characters of the architecture with the Summary of Mobile E-commerce...
In this article we highlight and discuss prominent aspects of context and adaptively in pervasive computing environments along with characteristics and categories of context, and context-aware systems. We also briefly refer to use, management and modeling of context in context-aware systems. This paper is not meant to provide an exhaustive review of literature but rather it aims to integrate and extend...
The Nomatic prototype system and communications ecosystem automatically infers users' place, activity, and availability from sensors on their handheld devices or laptop computers and then reports this information to their instant-messaging contacts.In our system, Nomatic (nomad and automatic), we explore a way to amplify and leverage this passive style of content creation by focusing on status messages...
