Ubiquitous computing is a new information and communication technology that utilize a large number of cooperative small nodes with computing and/or communication capabilities such as handheld terminals, smart mobile phones, sensor network nodes, contactless smart cards, RFIDs (Radio Frequency IDentification), and so on. This paper proposes the concept of ubiquitous learning that enables anyone to learn at anytime and anywhere by fully utilizing ubiquitous computing technologies. As the pilot system of the ubiquitous learning, this paper briefly introduces Digital Ubiquitous Museum that makes our daily living environments learning materials.
