Information and Communication Technology (ICT) is one of the key enablers for including underserved communities in economic and societal development across the world. Our research analyzes several banking service projects developing technical solutions for rural India. This poster presents an experience report based on systematic debriefing of involved project leaders and initiators, triangulated...
This contribution addresses the development of technology for the elderly with the aim to improve their general well-being. We report work on a prototype system named CARE that combines the functionality of a digital image frame with an active recommender mode. Recommendations are chosen on the basis of context information acquired by sensors embedded in the user's environment, and a well-being model...
Physical activities play important role in having better health. However, due to the nature of our jobs, most of us have developed sedentary habits and it is very seldom that we find dedicated time for exercise or other physical activities. Sedentary behavior has been identified as an important factor in preventing good health and there is a need to push adults to carry out physical activities regularly,...
The success of context-aware systems depends on intuitive user interface designs which facilitate communication between multiple devices. This paper presents Throw It, a natural user interface for sharing objects between mobile devices using gaze and hand gestures. For enabling gesture control, Throw It includes an off-the-shelf monochrome camera with infrared lights and a hand-held 6 degree of freedom...
The TAMALLE+[1, 2] is a prototype system that supports learners in their television viewing, enhancing informal language learning via interactive television and mobile phones. In this paper we describe a learner-centred study designed to elicit criteria for selection of those language learning object whose annotation or explanation through TAMALLE+ system could best enhance the advanced learner's...
With the fast development in mobile technologies and ever-increasing use of smart phones in everyday activity, researchers and developers are paying attention to exploit the advantages of mobile systems to support online teams. One important advantage would-be to implement the A3 paradigm: Anytime, Anywhere, Awareness, that is notifying users about ongoing activity in their online workspace. However,...
Most existing location-based services rely on ubiquitous connectivity to deliver location-based contents to the users. However, connectivity is not available anywhere at anytime even in urban centres. Underground, indoors, remote areas, and foreign countries are examples situations where users commonly do not have guaranteed connectivity but could profit from location-based contents. In this work,...
Rich context available creates varied applications on mobile device and makes end-user possible to customize personalized context-aware application. Meanwhile, problems arise that how to realize the service composition and present the service easy for end-user programming. In this paper, we refer to the notion of service component, design and implement a Context-Source Service Composition Prototype...
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,...
In this paper, we demonstrate the use of context-profiling for making access control decisions in mobile devices. In particular, we discuss the device locking use case, where the device locking timeout and unlocking method are dynamically decided based on the perceived safety of current context.
We present an ontology-based reasoning approach for saving energy in a smart home setting where a mobile phone can serve as a generic sensor which can collect the inhabitant's contextual data. The paper details an ontology that describes the smart home domain and a prototype to test the system. Finally, we conclude with lessons learned from our work in developing an energy-aware smart home prototype...
In this paper, we propose a context-aware system framework characteristic of two novel features. First, this framework is capable of modeling highly complex usage scenarios as a finite state machine while having transitions controlled by context information. And, this framework is designed with Augmented Reality capability as an integral component in its overall architecture to enable augmented interaction...
Recently, as smartphone is becoming more and more popular, concern about security threats against Mobile Communication Device (MCD) is getting higher. The MCD can not only become the target of the cyber attacks, but also be used as the tool of the cyber attacks. This paper proposes a context-based remote security control scheme for MCD. The proposed scheme consists of two systems: Context-based Mobile...
We describe a framework to exploit social network connections for targeted campaigns delivery in order to support local retailers in enhancing customer communication. In order to demonstrate its feasibility we implemented a client application enabling end users to find relevant coupons and offers and retrieve them after completing specific tasks. By integrating this application into a server infrastructure...
In this paper, we present a novel method for image annotation and retrieval on mobile device by using contextual information. Image annotation is an effective way for content based image retrieval. However, manual annotation is an expensive and time consuming work, especially for mobile device. Here, we propose a semi-automatic way to give image annotation on mobile device. There are rich contexts...
Virtual worlds have typically been isolated from the real environment, treated as separate parallel worlds. In this paper we show a scenario where context data collection from mobile devices can be used for augmenting virtual worlds with real-life data. Life-logging elements are used to control an avatar, in a virtual world, as a way to re-play experiences. The prototype system, which was implemented...
In this paper, we propose a context-aware Input Method Editor (IME) as a ubiquitous service for improving the input of text on mobile devices. In our proposed IME, it estimates the context of users according to position information from GPS (Global Positioning System) sensor or a presence information from the Internet. Simultaneously, it generates a personal context-aware dictionary dynamically from...
On the Internet, all sorts of community applications, especially social community applications, gain more and more importance every day. People in every type of community are eager to communicate, collaborate and inform themselves and others about news and information. So far the user interfaces for community applications have been Internet connected computers or advanced smart phones running standard...
The increasing competition in the mobile marketing market indicates that Mobile Marketing platform providers will be forced to integrate identity- and context information offered by the mobile network, in order to improve the efficiency of their applications. However, existing concepts/implementations only unassertively exploit available opportunities as well as insufficiently address emerging impacts...
