Abstract:
1. A device comprising: one or more projector control units that are configurable to respond to one or more substantially defined motions; and one or more image-stabilized projectors that are responsive to the one or more projector control units and that are responsive to one or more projection surface sensors that are configured to detect one or more features associated with the one or more projection surfaces, wherein the one or more projector control units that are configurable to respond to one or more substantially defined motions include: one or more projector control units that are operably associated with one or more control unit receivers that are configurable to wirelessly receive via the one or more projection surface sensors one or more signals that include information associated with one or more conformations of the one or more projection surfaces, the one or more projection surface sensors being co-located with the one or more projection surfaces and configured to detect the one or more conformations of the one or more projection surfaces resulting from a first magnetic ink applied to the one or more projection surfaces and resulting from a second magnetic ink applied to the one or more projection surfaces.
