Knowledge management and e-learning both address the same fundamental problem: facilitating learning in organizations. But they approach the problem with two different paradigms, resulting in two different types of system. This paper proposes context awareness with respect to the learner’s or employee’s context as a solution to bridge the gap. The project Learning in Process is illustrating a s...

オンラインチャットは,現在最も広く利用されているネットワーク上でのコミュニケーション手段 の一つである。しかし,そこでは基本的に文字情報しかやり取りできないため,非言語情報が欠落 してしまう。この結果,同じ文であっても,その発話者がどんな心境や状況でその発話をしたのか が不明瞭となってしまう。そこで本研究では,オンラインチャットで必ず行われ,かつもっとも自 然な行為である「打鍵」に着目する。チャットで自然に行われるこのような打鍵行為によって生 じる物理的作用である振動を対話相手に伝達し,触覚情報として提示することにより,対話状況ア ウェアネスを伝え合うことを試みる。プロトタイプシステムである Tangible Chatを用いた実験 の結果, 複数の話題の同時進行が減少し,発話順序交代が円滑化したことが確認された。また,感 情の伝達による対話内容の活性化についての有効性も確認することが...

This article illustrates the vivid research field of hybrid and context-aware recommender systems. Moreover, two own approaches to deal with context-awareness in recommender systems, are described in detail.

The paper analyzes the globally recognized cultural move towards a more learner-centred education and discusses the implications for the adoption of mobile technologies and design for learning. Current expectations vis-à-vis learner attributes, skills and competences are explored. The pervasiveness of mobile technologies is precipitating these developments, whilst also generating a distinct mob...

Two major properties will characterize networks in the future: ‘3C everywhere’ and ‘physical interaction’. These two properties promises a computing infrastructure that seamlessly and ubiquitously aids users in accomplishing their tasks and that renders the actual computing devices and technology largely invisible. This paper begins by sketching pervasive computing scenarios. Next, we delve dee...

In a mobile setting, users use, handle and search for online information in a different way. Two features typically desired by mobile users are tailored information delivery and context awareness. In this paper, we elaborate a demo application that is built upon the existing SCOUT framework, which supports mobile, context-aware applications. The application illustrates the use of intrinsic mobi...

According to a recent definition by Dey and Abowd context is any information that can be used to characterize the situation of an entity. An entity is a person, place or object that is considered relevant to the interaction between a user and an application, including the user and the application themselves. A system is context-aware if it uses context to provide relevant information and/or ser...

We describe the design and preliminary evaluation of a virtual agent that provides continual bedside companionship and a range of health, information, and entertainment functions to hospital patients during their stay. The agent system uses sensors to enable it to be aware of events in the hospital room and the status of the patient, in order to provide context-sensitive health counseling. Pati...

Shopping in the real world is becoming an increasingly interactive experience as stores integrate various technologies to support shoppers. Based on an empirical study of supermarket shoppers, the authors designed a mobile context-aware system called the Context-Aware Shopping Trolley (CAST). The purpose of CAST is to support shopping in supermarkets through context-awareness and acquiring user...
