Abstract
Visual images projected on a projection surface by a projector provide an interactive user interface having end user inputs detected by a detection device, such as a depth camera. The detection device monitors projected images initiated in response to user inputs to determine calibration deviations, such as by comparing the distance between where a user makes an input and where the input is projected. Calibration is performed to align the projected outputs and detected inputs. The calibration may include a coordinate system anchored by its origin to a physical reference point of the projection surface, such as a display mat or desktop edge.
