er presents an approach to deriving an abstract geometric model of a table from a physical representation. The technique developed uses a graph of constraints between cells which ...
In this paper we introduce the TessalTable, a collaborative play system for learning about tessellations and symmetry through augmented pattern blocks. Children use tiles to pick ...
In [Spi], we developed a category of databases in which the schema of a database is represented as a simplicial set. Each simplex corresponds to a table in the database. There, our...
