Abstract: A transaction automation and archival system is provided for controlling, real-time logging, and archiving complex commercial transactions such as the purchase and financing of an automobile. The heart of the system is an electronic contract disclosure unit, or ECDU. The ECDU includes a digitizing display that includes a video display for imaging to participants the various documents involved in the transaction and a digitizer for allowing participants to sign, indicate choices, and otherwise interact directly on documents and images presented on the display. A computer controls the entire progress of the transaction, and thus controls the collaborative space occupied by the participants to the transaction.
