Recent rapid advancement in both pervasive mobile computing and cloud service has been driving numerous new applications in the ubiquitous media consumption. To provide mobile user with richer experiences, it is desired for the service providers to offer highly relevant recommendations of media content to the users by exploring user-user, user-media and user-context relationships. Furthermore, contemporary...
Geospatial technologies in conjunction with wireless grids will offer a context for locating and coordinating team activities in such a way that the nature of each team member's effort may be known and understood by other members. This constructed group knowledge enables teams to respond to unforeseen and emergent contingencies and act in concert through the active interpretation of shared artifacts...
The traditional techniques developed to deal with the issues in business process improvement don't meet the current and future organizations requirements. The existing methods are technology/fixed business process centric and not user-centric. The systems that can recognize the context of the user can bring great benefits especially enabling businesses to run more efficiently from any location. In...
The topic of mobile services has piqued the interest of practitioners. Mobile service providers invest many resources to provide mobile services of higher quality in the hope of gaining more business opportunities and higher customer satisfaction. They often increase the service quality through the use of personalization, i.e., generating customized mobile content for each individual. Despite the...
Mobile phones are increasingly able to read auto-id labels, such as barcodes or RFID tags. As virtually all consumer products sold today are equipped with such a label, this opens the possibility for a wide range of novel digital services building on physical products. In this paper, we discuss the problems that arise when such novel applications are deployed, and present a unified system architecture...
Information foraging and sensemaking with heterogeneous information are context-dependent activities. Thus visual analytics tools to support these activities must incorporate context. But, context is a difficult concept to define, model, and represent. Creating and representing context in support of visually-enabled reasoning about complex problems with complex information is a complementary but different...
Recommendation Systems have become an important research area in mobile computing. Although various recommendation systems have been developed to help users to deal with information overload, few systems focus on proactive information recommendation. This paper presents a news recommender system that proactively pushes just-in-time personalized news articles to mobile users based on user's contextual...
We envision a sensor-enabled mobile system to assist organizers and participants of public events in emergencies and evacuation situations using human computing principles. By autonomously detecting elements of emergent collective behavior (e.g. clogging, queuing, herding), efficient interaction and information sharing with specific groups in the crowd is enabled. We have previously shown the technological...
Effectively guiding people in complex and highly dynamic work environment requires advances in high-level declarative activity models that can describe the flow of human work activities and their intended outcomes, as well as novel user interface models for distributing guidance information across time and space. This paper describes a new line of research aimed at developing a new programming and...
We observe two of the recent trends in information technology. Cloud Computing (CC) is widely accepted as an effective reuse paradigm. Mobile Computing with Mobile Internet Device (MID) such as iPhones and Android devices becomes a convenient alternative to personal computers by integrating mobility, communication, software functionality, and entertainment. Due to the resource limitations of MIDs,...
The small form-factor of mobile handsets and the longer, variable latency of cellular networks are major hindrances to good user experience in mobile web related activities. Existing approaches have yet to adequately address the usability concerns caused by them. This paper describes the design and prototype implementation of MIntOS (Mobile Interaction Optimization System), a system for improving...
This paper proposes an integrated conceptual model for analyzing user adoption behaviors towards mobile marketing platforms from a two-sided market perspective. Both the consumer side and the merchant side are modeled based on extending classical theories with newly introduced factors reflecting cross network effects, and the two sides are integrated in the overall model which reveals the dynamic...
Mobile devices that are capable of playing Internet videos have become wide-spread in recent years. Because of the enormous offer of video content, the lack of sufficient presentation space on the screen, and the laborious navigation on mobile devices, the video consumption process becomes more complicated for the end-user. To handle this problem, people need new instruments to assist with the hunting,...
Mobile devices are becoming mandatory equipment in modern life. However, the available interfaces are usually not suitable for accepting data input in a friendly and reliable fashion. Accordingly, a context- based approach can represent a useful alternative for circumventing threats in a mobile computing scenario. In this paper, we present a proposal based on context-aware authentication, considering...
With the proliferation of mobile devices, the challenge today is to provide users with applications that are of real value. These applications are, in most of the cases, mobilized versions of desktop applications that fit the contextual requirements of mobility constraints. When developed from a desktop application, it is difficult to align the mobile application with user expectations because of...
This paper describes concepts, design, implementation, and performance evaluation of a 3D-based user interface for accessing Ambient Intelligence Environments (AmIE). The generic interaction model of the described work addresses some major challenges of Human-Environment-Interaction such as cognitive overload and manual device selection, loss of user control, missing system image or over-automation...
Augmented Reality enhances the user perception by overlaying real world information with computer-generated information. In this paper, we study the user experience in Augmented Reality for the deployment of real-time adaptation. In the context of thin-client mobile Augmented Reality, the rate is often constrained due to limitations in the transmission link. End-to-end delay, frame rate, image size...
As mobile smart phones are being equipped with multiple radio interfaces and sensors, they are becoming capable of continuously collecting context information related to the users and the environment. This information can be utilized in different applications and services for providing rich, context-aware experiences. In this paper, we present a client-server platform that enables life logging, via...
Technology acceptance research has tended to focus on extrinsic motivation based on sole theoretical paradigm. Building upon and integrating the key findings of four closely related theoretical paradigms (the technology acceptance model, the theory of planned behavior, innovation diffusion theory, and the flow theory), we developed and test a more comprehensive and unified model in the context of...
User interface is one of the main challenges for designing mobile application. The importance of user interface is all about to retain user's loyalty which can be gained by offer user friendly interface and usability. The research focus on main issues of designing mobile application which is "how to display all the information and elements on the small screen of mobile device?". This research...
