Abstract
A hand-held printer system is designed for printing a stored image onto a surface or other media. In particular, various embodiments are adapted for hand-held printing onto the surface of a whiteboard. In embodiments, the printer system comprises a marking mechanism including at least one print head, a global position sensing system that senses a position of the at least one print head, and a control mechanism that actuates the at least one print head based on the sensed position. In other embodiments, the system comprises a local position sensing system that senses a position of the at least one print head relative to a drawing surface.
Claims41
A hand-held printer system, comprising:
- a marking mechanism including at least one print head;
- a global position sensing system that senses a position of the at least one print head relative to a printing surface or medium;
- and
- a control mechanism that actuates the at least one print head based on the sensed position.
A hand-held printer system, comprising:
- a marking mechanism including at least one print head;
- a local position sensing system that senses a position of the at least one print head relative to a printing surface, the local position sensing system comprising a video-based system including a plurality of glyph marks on the printing surface and at least one video camera associated with the at least one print head;
- and
- a control mechanism that actuates the at least one print head based on the sensed position.
A method for marking on a surface using a hand-held printer, comprising:
- moving a marking mechanism over a surface;
- sensing a position of the marking mechanism relative to the surface in a global coordinate system;
- and
- actuating the marking mechanism to create a mark on the surface based on the sensed position.
A method for marking on a surface using a hand-held printer, comprising:
- moving a marking mechanism over a surface including a plurality of glyph marks;
- sensing a motion of the marking mechanism relative to the surface using the plurality of glyph marks;
- and
- actuating the marking mechanism to create a mark on the surface based on the sensed position.
