Mobile users have the capability of accessing information anywhere at anytime with the introduction of mobile web search. However, they still need to devote time and effort in order to retrieve relevant information in mobile devices. Conversely, context is proposed to reduce users time and effort. The recognition of context is supported by the availability of embedded sensors in mobile devices. In...
Mobile social applications are becoming increasingly popular with a growing number of users turning to mobile devices for socializing, information sharing, retrieval or related activities, and/or gaming. The increased interest in the domain has resulted in numerous application prototypes being reported in the recent years that combine elements of socializing, gaming, and information related activities,...
Sharing sensitive context information among multiple distributed components in mobile environments introduces major security concerns. The distributed sensing, processing and actuating components of these applications can be compromised and modified or impersonated to extract private and confidential information or to inject false information. In this paper we present the Anubis protocol for remote...
We have developed a prototype platform for contextual information access in mobile settings. Objects, people, and the environment are considered as contextual channels or cues to more information. The system infers, based on gaze, speech and other implicit feedback signals, which of the contextual cues are relevant, retrieves more information relevant to the cues, and presents the information with...
In this paper, we address the process of generating cartographic maps on-the-fly. Despite the existence of intensive research works, this process is still characterized by its complexity, time-consuming processing, and lack of flexibility. While web users are having an improved access to spatial data, mobile users are still facing problems in getting personalized maps that fit their limited display...
This paper describes the design and implementation of location and situation based adventure games. The prototype uses different types of sensor data - including 3D acceleration data and XPS - to determine the current positions and activities of the players. Depending on the continuous classification, data and quests are retrieved accordingly from a central information system and visualised for the...
Context-aware computing benefits mobile applications by adapting systems behavior through user surrounding. However, contextualized information retrieval for mobile user in mobile P2p environment still remains a challenging problem. In this paper, we present JHPeer framework for mobile information retrieval (IR) in hybrid peer to peer (P2P) networks. JHPeer incorporates context engine to fit on mobile...
Most tourists today expect a friendly tour guidance and services considering their individual preferences and actual situation while protecting their privacy. The ideal is an intelligent guide taking care of the whole organization and execution in time. This is the main objective of the context-based Personalized Mobile Tourist Guide (PMTG). Tourist's profiles or visiting background is stored in a...
Mobile device can be used as a medium to send and receive the mobile Internet content. However, there are several limitations using mobile Internet. Content personalisation has been viewed as an important area when using mobile Internet. In order for personalisation to be successful, understanding the user is important. In this paper, we explore the implementation of the user profile at client-side,...
Mobile-enabled social networks applications are becoming increasingly popular. Most of the current social network applications have been designed for high-end mobile devices, and they rely upon features such as GPS, capabilities of the World Wide Web, and rich media support. However, a significant fraction of mobile user base, especially in the developing world, own low-end devices that are only capable...
Context-awareness has become a desired key feature of today's mobile systems, yet, its realization still remains a challenge. On the one hand, mobile computing provides great potential for adaptations based on sensed contextual information. On the other hand, the lack of dependability in mobile networks hampers an efficient provision of this information to requesting clients. In this paper we present...
This panel paper presents motivations for discussing mobile media search and contains statements from the panelists who are industry research leaders in this field.
With the emergence of pervasive computing environments, mobile information sharing and retrieval is becoming an exciting domain that challenges information scientists. In this paper, we describe a hybrid peer to peer context-aware framework for building mobile information sharing applications. A scalable and flexible architecture based on JXTA is presented. The architecture called "JHPeer"...
In our daily life we frequently use mobile devices to interact with the people and things on the Internet. However, finding the right things when needed is getting difficult and frustrating. In this paper, we introduce a relatively new problem of non-collaborative personal interest mining using contexts and ratings available for items of interest. We present multi-step algorithms to extract personal...
We present an approach for personal information management for mobile devices like PDAs based on the Semantic Desktop. The main objective is to design and realize a recommendation system to identify interesting items (e.g. messages or documents) based on the current context (time and location) and a user's personal ontology. To do so, our algorithm uses an evaluation function to traverse the graph...
