In this paper, we describe the design and implementation of Teaching Table -- an interactive tabletop audio-visual device aimed at enhancing the learning experience for pre-kindergarten children by involving them in physical activities. Using electromagnetic sensing technology, the table can track tagged objects placed on its surface, accurately identifying(More)
This paper develops a semiotic operand, the hypersign. The hyperlink is structurally amenable to semiotic analysis. Anchor and destination function as signifier and signified. Especially significant are digital surrogates, such as Amazon catalogue entries, and Google gists, which are systematically produced hypertextual signifier-signified pairings.(More)
Semantic web researchers tend to assume that XML Schema and OWL-S are the correct means for representing the types, structure, and semantics of XML data used for documents and interchange between programs and services. These technologies separate information representation from implementation. The separation may seem like a benefit, because it is(More)
In screen-based experiences, the screen itself can become the physical device used for interaction. The "move-ability" of the screen affords interactivity between the screen artifact and the viewer, and between the virtual and physical spaces. We have created a movable screen interface, called the <i>tilting table</i>, which provides a display surface via(More)
We continue to develop a generative hypermedia system that uses composition for browsing, collecting and organizing information samples from web pages. The system's generative actions of collecting information samples and composing them visually are conducted iteratively over time, based on an adaptable user model. The system presents the ongoing generation(More)
1 In the postmodern age, people interact with information on a daily basis. The process tends to become routinized. Yet, information has the potential to stimulate imagination, and the emergence of new ideas. We are endeavouring to open the space of everyday experiences with information. People need to create, work with, share, and present collections of(More)
combinFormation is a tool that enables browsing and collecting information elements in a generative space. By generative, we mean that the tool is an agent that automatically retrieves information elements and visually composes them. A combinFormation session presents a dynamic, evolving recombination of information elements from different sources. The(More)
Information is data that communicates, representing stuff of significance to human beings. Information semantics are formal representations that define structures of information. We develop an inter-language translation framework for information semantics. By using programming language mechanisms for translation across languages, including a formal type(More)
