Mobile app testing and evaluation requires exposing the app to a wide array of real world context conditions viz. location, sensor values, network conditions etc. Such comprehensive context conditions are difficult to create in a development environment on a real device, therefore, simulating them in a mobile emulator is a promising alternative. We present ContextMonkey, a framework for context generation...
Context-awareness is a very popular method for improving the smart-phone user experience in a certain context, based on device sensor data. This paper present an application that collects data from different sensors at predefined intervals and store them in a database for further analysis. The application also has a web graphical visualizer for the data that helps analyzing the sensor values at certain...
It has become easier to create a lifelog by using smart phones. Lifelogs can be used in several ways. However, some problems exist in memory recollection; as many lifelogs owned by a person are partial information, it is impractical to remember days themselves. Therefore, a lifelog sharing system for memory recollection is proposed. The system elicits related information from other people's lifelogs...
Augmented Reality is an advance technology that enhances the real world by overlaying digital data on top of it. When Augmented Reality (AR) experience is delivered on mobile devices it is termed as mobile augmented reality (MAR). MAR is state-of-the-art technology that has completely revolutionized the way of accessing and interacting with information thus invoking new experiences for users all around...
Mobile software technologies have become increasingly important in building disaster response system to cope with natural and man-caused emergency situations. In this paper we present a context-aware disaster response system that analyzes the contextual information of public users and disaster environment, and then delivers customized instructions in an appropriate format to the mobile handsets of...
This demo presents a framework for personalizing data access on the basis of the users' context and of the preferences they show while in that context. The system is composed of (i) a server application, which “tailors” a view over the available data on the basis of the user's contextual preferences, previously inferred from log data, and (ii) a client application running on the user's mobile device,...
Context-awareness has been successfully included in the mobile device applications due mainly to the presence of numerous sensors and the access to several communication networks. Therefore, this paper presents a context-aware framework based on geolocation for a health care governance system. While enabling remote health diagnosis of a patient using his/her own mobile device, the proposed system...
The paper presents an idea of a context-aware application, which collects context data from many different sources, stores them in a dedicated database and makes use of it to support flexible scenarios for end users. Using open APIs it integrates different types of context information provided by: Unified Communication system, APIs exposed by communication service providers and information from Machine...
In this paper, we present a novel method for deep user profiling using information available on social networks about a user's activities and interests. We use this information to personalize the search for the user and make results available via web and low end mobile phones. In addition to using a user's profile as a context, we also use the context of location and implement a location based search...
Due to the heterogeneity involved in smart interconnected devices, cellular applications, and surrounding (GPS-aware) environments there is a need to develop a realistic approach to track mobile assets. Current tracking systems are costly and inefficient over wireless data transmission systems where cost is based on the rate of data being sent. Our aim is to develop an efficient and improved geographical...
Traditional phone communication is designed on the assumption that caller actively telephones callee without any knowledge of callee's situation. Caller often doesn't make successful calling as callee is not available at that time. Along with the development of pervasive computing and sensor technology, context information of user can be sensed, inferred from pervasive environment. Before starting...
Mobile application development is more challenging when context-awareness is taken into account. This research introduces the benefit of implementing a Mobile Service Oriented Architecture (SOA). A robust mobile SOA framework is designed for building and operating lightweight and flexible Context-Aware Mobile Application (CAMA). We develop a lightweight and flexible CAMA to show dynamic integration...
There are several radio access technologies providing connectivity for mobile devices. In the future, more and more mobile devices will be capable of supporting more than one access technology. For being able to use these technologies simultaneously, there is a need for multihoming capabilities. Due to the variety of access technologies and the ability to use them simultaneously, new concepts for...
Current learning systems are frequently criticized for their predominant focus on explicit, and in particular, written representation of knowledge. There are communities around the world where verbal knowledge is more pervasive than written knowledge. This paper presents a study of how such knowledge can be accessed anywhere/anytime, in a form that may be used and understood in a standardized format,...
The diversity of terminals used by the user to access resources (personal digital assistant, mobile phone, etc.) using several types of networks (wireless, local, etc.) generates a growing need to adapt services dynamically to the user's context. In this article, we present our architecture that aims at adapting content and presentation of services to the user's context. We realize the content adaptation...
We present a semantic context management framework named Context Torrent, which can make various types of context information be semantically searchable and sharable among local and remote context-aware applications. We implement this framework on the Google Android platform with its elegant application support. An open source RDF parser has been extended to effectively get RDF triples from files...
Requirements Elicitation is the process of discovering, extracting and gathering requirements for a system through communication with the stakeholders. Very often the process is carried out by observing the workplace and analyzing their needs at the work context. Ethnography, it is an elicitation technique that supports context-aware requirements elicitation. Common tools used in requirements elicitation...
The proliferation of mobile computing devices and local-area wireless networks has fostered a growing interest in location-aware systems and services. We consider location as prime form of context information. The developed framework joins the concepts of location and user tracking as an extension for a new type of mobile information systems. The framework uses a WiFi network infrastructure to let...
