The electronic calendar usually serves as a personal organizer and is a valuable resource for managing daily activities or schedules of the users. Naturally, a calendar provides various contextual information about individual's scheduled events/appointments, e.g., meeting. A number of researchers have utilized such information to predict human behavior for mobile communication, by assuming a predefined...
Mobile or cellular phones can record various types of context data related to a user's phone call activities. In this paper, we present an approach to discovering individualized behavior rules for mobile users from their phone call records, based on the temporal context in which a user accepts, rejects or misses a call. One of the determinants of an individual's phone behavior is the various activities...
Excessive mobile phone use has gained attention in the media recently, where it has been associated with driving fatalities and productivity decrements as well as social embarrassment. To provide successful interventions, there is a need to understand why some mobile phone owners can't resist the urge to use their devices. Much prior research has investigated excessive use through the perspective...
The commonly used phone communication is designed on the assumption that caller actively telephones callee without any knowledge of callee's situation. Along with the development of computing and sensor technology, context information of user can be sensed, inferred from pervasive environment. Caller can determine in what situation callee locates with context information of callee. Some research work...
Mobile devices like PDAs or mobile phones have become widespread. Similarly network functionality like GSM, Bluetooth or WLAN has become a standard. Nevertheless, not many applications take mobility into account. An application and its communication component are tightly coupled and the applications assume that network behavior does not change. Here in this project we propose and implement a new component...
In this paper, we describe wireless grids, an emerging technology that enables ad hoc sharing of resources (such as screen, services and microphone) on edge devices (such as mobile Internet devices, laptops and mobile phones). As wireless devices have become common, and "smart," wireless grids have become practical. To highlight the capabilities of wireless grids to support collaborative...
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 a Wizard-of-Oz experiment we investigate to what degree automatic activity recognition could support the use of prioritized lists for nursing documentation on hand held mobile devices. The study involved 15 nurses, 60 patients records and over 250 documented processes at a geriatric care ward. Based on time effort, interaction complexity, error rate and subjective system perception our wizard of...
A challenge in the convergence of heterogeneous networks is how to combine the ubiquitous resources and provide the diversified individual services. By this, the vision of adaptive and context-aware service provision becomes possible and offers new opportunities for pervasive computing. In this paper, we describe an approach that addresses the convergence of wireless personal area and wide area networks...
The objective of this paper is to explore new methods of interaction design for enhancing children's cognitive ability. Based on theories of cognitive psychology and combined with concepts of user experience in interaction design, this paper offered a systemic analysis of children's cognitive ability and cognitive development mechanism, outlined the interaction design principles and new methods of...
We consider a community of agents in the domain of patient healthcare where the community is populated by personal assistant agents residing on mobile phones assisting the human patients and sever agents managing the services offered to the patients. In this scenario, we look at patient care polices, and interpret them in the context of crisis situations. Existing models dealing with behaviours of...
This paper presents a ringtone recommendation agent system which utilizes user's emotion to recommend an appropriate ringtone and the suitable volume level of a mobile phone. The system uses a Bayesian network (BN) to infer user's emotion and the volume level at the current situation. After inferring user's emotion, a ringtone is selected from the pool of various kinds of genres of ringtones. Also,...
We present a novel context acquisition and management middleware for mobile phones based on Qt (C++ based cross-plattform API) for S60 called mSense. In our middleware, sensor nodes encapsulate platform level APIs for seamlessly accessing hardware sensors, simulated sensors or web services. Aggregators (channels) combine information from other nodes to generate new knowledge. For example, GPS, accelerometer...
In this paper, we describe the design and implementation of a location and situation based pervasive mobile adventure game named Sportix. The prototype uses different kinds of sensor data - including 3D acceleration data and XPS - to determine the current position and activity of the player. Depending on the firm classification, data and quests are retrieved accordingly from a central information...
Tagging technologies like barcode and RFID have made a revolution in our lives. These technologies when combined with mobile technology can result in many potential applications. These applications can range from simple object identification applications where the user scans a tag of a certain object and then get information about that object, to complex applications where tags are used as a mean...
What is the role of mobile devices in education? Mobile phone ownership has proliferated at an explosive rate over the last decade. The entrenchment of this technology in everyday life necessitates a critical examination of the roles it can play in education. A varied cross-section of case studies in mobile education was selected and analyzed with the primary aim of providing a critical landscape...
We describe a framework for wireless sensor network (WSN) based mobile mashup applications. The framework consists of four functional components: WSN, mobile gateway, context management platform, and mashup server. The WSN deployed in the application domain senses the physical phenomena and the human-environment interaction and expresses them in sensor readings. The mobile phone is used as the gateway...
In this paper we describe a context-sensitive way to change an active mobile phone profile. We present a method to create a proactive and adaptive phone profile control system that automatically adapts the profile to the best alternative based on the current context. The adaptation is based on recognizing patterns of human practices, which may change over time. The control system is implemented with...
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...
Inference of high-level context is becoming crucial in development of context-aware applications. An example is social context inference - i.e., deriving social relations based upon the user's daily communication with other people. The efficiency of this mechanism mainly depends on the method(s) used to draw inferences based on existing evidence and sample information, such as a training data. Our...
