The application of a technology to a task can often become the most important point of interaction design. In various cases, projects had a pre-existing technology or even fully designed product that needed an interactive software interface.

These applications were built as prototypes or simulations so that I might learn from the process and the use of the design. Most were taken to target customers to help evaluate the use of a particular concept model or design solution. Many clients provided engineers to assist in the design decisions and the creation of partially or fully functional prototypes.
