Patent Images
1. A spatially-aware projection pen system, comprising:
- an input mechanism configured to be activated and deactivated by a user;
a position tracking mechanism configured to determine a position of the spatially-aware projection pen within a three-dimensional space and relative to a display surface;
a memory configured to store design data, image data, and an application program, wherein the design data comprises computer-aided design (CAD) data;
a processor configured to;
execute the application program to generate at least a portion of the image data based on the CAD data and printed content on the display surface,receive input signals from the input mechanism and the position tracking mechanism, andgenerate a projected image based on the image data, the input signals and the position of the spatially-aware projection pen, wherein the proiected image includes a plurality of visual components, and wherein a geometry and a location of each visual component corresponds to a different content portion of the printed content;
a projector configured to display the projected image overlaid on the printed content, wherein a location of the projected image is locked relative to the printed content and remains static as the position of the spatially-aware projection pen changes; and
an enclosure configured to be grasped by a human hand and house the input mechanism, the position tracking mechanism, the memory, the projector, and the processor.

Abstract
One embodiment of the present invention sets forth a technique for providing an end user with a digital pen embedded with a spatially-aware miniature projector for use in a design environment. Paper documents are augmented to allow a user to access additional information and computational tools through projected interfaces. Virtual ink may be managed in single and multi-user environments to enhance collaboration and data management. The spatially-aware projector pen provides end-users with dynamic visual feedback and improved interaction capabilities.
