Self Calibration for the DigitalDesk

Pierre Wellner
The DigitalDesk has one or more cameras that point down at the desk, and users can select areas in a camera's field of view to perform operations such as "copy and paste" or character recognition on selected areas of paper documents. This report describes how the system supports the ability to indicate a specific point or region precisely in the frame-grabber's coordinate system through a pointing device and projected display.
