Using a 3D Puzzle as a Metaphor for Learning Spatial Relations
We introduce a new metaphor for learning spatial relations--the 3D puzzle. With this metaphor users learn spatial relations by assembling a geometric model themselves. For this pu...

Compositional Model Repositories via Dynamic Constraint Satisfaction with Order-of-Magnitude Preferences
The predominant knowledge-based approach to automated model construction, compositional modelling, employs a set of models of particular functional components. Its inference mecha...

ClearPen: improving the legibility of handwriting
We describe the application of a pen model, and sub-pixel addressing (ClearPen), to render handwriting on an LCD display. This technique is shown to improve the legibility of hand...

Ubiquitous Data Management in Knowledge Sifter via Data-DNA
This paper proposes to model and represent an object’s digital persona by means of a conceptual model that uses fragments of schemata that are termed data-DNA. The object may be...
