During the past five years, we have explored the use, potentials and challenges of Blended Interaction spaces. In addition, we have a long background in developing and exploring methods for collaborative design. In this workshop paper, we give an overview of our work and present our visions and ongoing research in developing Blended Interaction spaces for collaborative design. We then identify ...

In this paper, we study CAT(0) spaces with nonlocally connected boundary. We give some condition of a CAT(0) space whose boundary is not locally connected.

We exploit the geometry of the 4D hypercube in order to visualize tetrachromatic images.

We construct several non-trivial examples of CAT(1) spaces by using the idea of free construction.

This paper illustrates how the model of computational media can be introduced in the field of higher education. In our practical work, we identified four distinct design spaces for learning media and named them as follows: artifact design space, agent design space, process design space, and business model design space. We have applied the design space approach in the UNIVERSAL project, an open,...

Our main result in this paper is that a Banach space X embeds into L, if and only if l~(X) embeds into Lo; more generally if 1 _-< p < 2, X embeds into Lp if and only if lp (X) embeds into L~,.
