Abstract
We have explored the design and development of magnetically-resonant tag readers for application to tangible computer interfaces. To this end, we constructed a ringdown tag reader and a swept-frequency tag reader, both capable of real-time continuous interaction with multiple tagged objects. Although the ringdown reader worked well for smaller numbers of tags, the swept-frequency tag reader proved more efficient for work with twenty to thirty tags, and so we did further work to extend and apply it. Graphical and musical applications were developed for the swept-frequency tag reader and proved its usability for driving tangible desktop interfaces. Finally, a six-coil variant was constructed in order to determine the three-dimensional position and orientation of tagged objects. This thesis describes both reader systems, outlines our demonstration applications, and gives first test results from the multiple-coil tracker.
