Adpating to user context versus adapting to individual user features or behaviour patterns has been a topic of recent discussion. We believe both types of adaptation are valuable and the decision of which to apply, or how to combine the two, is domain or application specific. As an illustration, this paper presents two approaches to adapting the interface according to the type of user and the e...

In this report we propose a number of techniques to reduce energy consumption for mobile computers. We use extra dedicated low-power modules to cut on processor cycles of the main CPU, i.e. hardware and software decomposition. These modules are autonomous and can be powered down individually. Furthermore, as networking consumes a large part of a mobile system’s battery resources much effort is ...

Collaborative learning is widely used in elementary classrooms. However, when working without technological support, some problems can be detected. We describe how weaknesses in coordination, communication, organization of materials, negotiation, interactivity and lack of mobility can be solved with a mobile computer supported collaborative learning environment with Handhelds interconnected by ...

Standards, assessment, and accountability movements are changing practices in public education. These changes require extensive data gathering and analysis. Teachers and administrators are overwhelmed by the demands, yet handheld computers offer a means to collect data unobtrusively and in ways that may provide better accountability. Within this art icle, uses of the handheld computer in the st...

A ubiquitous wearable computing infrastructure is now firmly entrenched within organizations across the globe, yet much of its potential remains untapped. This paper describes how the handheld computers and mobile phones in today’s organizations can be used to quantify face-to-face interactions and to infer aspects about a user's situation, enabling more creative and transparent functioning of ...

We developed a prototype system that can provide reliable communications in the event of a medical disaster. The system uses redundant wireless protocols on handheld computers to deploy medical personnel, and to facilitate communication between ancillary treatment sites and a command center.

OBJECTIVES Our objective was to design and develop a mobile clinical decision support system for emergency triage of different acute pain presentations. The system should interact with existing hospital information systems, run on mobile computing devices (handheld computers) and be suitable for operation in weak-connectivity conditions (with unstable connections between mobile clients and a se...

This paper considers the potential for the use of learner models to promote reflection in combined desktop PC / mobile intelligent learning environments. This is illustrated with reference to two such environments. The first is an adaptive tutoring system that has two versions (for the desktop PC and handheld computer), each of which has the same interaction options. In the second, the main tut...
