Bill Buxton has been collecting input and interactive devices whose design struck him as interesting, useful, or important. In the process, he has assembled a great collection spanning over 30 years of the history of pen computing, pointing devices, touch technologies, as well as an illustration of the nature of how new technologies emerge.
The collection can be browsed in HTML or via the PivotViewer Silverlight interface. PivotViewer provides a richer experience with faceted filtering, search, and hypertext links for metadata. Each device includes Buxton's photos, notes, details about the device's release date, retail value, and name of the creator.
