HTW Demonstrations

The How Things Work Project of the Stanford Knowledge Systems Laboratory is developing knowledge-based technology to offer intellectual assistance in all stages of the life cycle of engineered products. One of the products of the project is the Device Modeling Environment (DME), a system that assists in model formulation, simulation, and documentation of designed artifacts.

This document is an entry point for interactive documentation on DME and other HTW products and services. Demonstrations are offered as hypermedia documents on the Web. Some are virtual documents that are generated by the software being demonstrated, as the reader browses the information.

We think these documents are good examples of what can be done with the Knowledge Medium.

Guided Tours
