4. I-2-I Alleviating absence by use of the "Telephonoscope". A mirror is envisage as the display screen. [From Albert Robida "Le Vingtième Siècle, 1880s] iSpace project meeting between Royal Institute of Technology and Stanford University

5. Telepresence As described by teleoperators, presence is the sensation of being at the remote worksite rather than at the operator`s control station. Marvin Minsky (1980) in reference to teleoperation systems Teleoperators and Telerobotics, (Held & Durlach, 1992) Simulated environments, (Rheingold, 1991; Sheridan, 1992).

6. Definition of Presence at a Distance Presence at a distance is defined as the subjective experience of being in one place or environment, even when one is physically situated in another. Presence journal 2000

7. Definition of Presence in Virtual Environments Presence is defined as the subjective experience of being in one environment (there) when one is physically located in another environment (here). Measuring Presence in Virtual Environments, (Witmer Bob G. and Singer Michael J., 2000) As applied to my own research, presence refers to the experiencing of both mediated bodies and spaces.

8. Two models of mediated communication traditional communication model telepresence view Defleur & Ball-Rokeach, 1989; Schramm, 1974; Shannon & Weaver, 1962 Steuer (1993) after Krueger (1991) BA BA Shared virtual reality

9. The main research question How do we produce a sense of presence and reality at a distance between individuals physically separated in space?

10. Factors creating a sense of presence and reality sensory environment individual preconditions content characteristics vividness interactivity and control company of others depth & breadth imagination emotional state associative context suspension of disbelief plot and story narration and dramaturgy presentation and execution [Enlund N.]

11. Experiments and user studies experiment with new methods of creating human-to-human Interaction, including for musical and artistic performance. strong international collaboration produce “pre-competitive” results in the form of prototypes, demonstrators and user studies.

32. A Knowledge Manifold is a structured information architecture that supports a number of different strategies for information hiding (encapsulation). can be regarded as a Knowledge Patchwork, with a number of linked Knowledge Patches, each with its own Knowledge Gardener. gives the users the opportunity to ask questions and search for certified human Knowledge Sources. can be used to design learner-centric, knowledge-pulling interactive learning environments that support Question Based Learning.

33. A Knowledge Manifold (cont.) has access to distributed archives of resource components. allows teachers to compose components and construct customized learning environments. makes use of conceptual modeling to support separation of content from context. contains a concept browser (Conzilla) that supports these principles and activites.

34. The different Knowledge Roles of a KM The knowledge cartographer The knowledge composer The knowledge librarian The knowledge coach The knowledge preacher The knowledge plumber The knowledge mentor constructs context-maps. fills the context-maps with content. composes content components into learning modules. cultivated questions. provides live answers. connects questions with appropriate preachers. provides motivation and supports self-reflection.

35. Design principles for Concept Browsers separate context (= relationships) from content. describe each context in terms of a context-map. assign an appropriate set of components as the content of a concept or a conceptual relationship. filter the content components through different aspects. label all resources with a standardized data description (metadata) scheme (LOM-IEEE). transform a content component which is a context-map into a context by contextualizing it.

39. CyberMath: A Shared Virtual Environment for the Interactive Exploration of Mathematics teaching of both elementary, intermediate and advanced mathematics and geometry. Goals: The CyberMath system should allow: Means: Making use of advanced VR technology (e.g. DIVE). global sharing of resources. the teacher to teach in a direct manner. students to work together in groups. teachers to present material that is hard to visualize using standard teaching tools.
