SPATIALLY-AWARE PROJECTION PEN INTERFACE
First Claim
1. A computer-implemented method for configuring a spatially-aware projection pen to provide a user interface, the method comprising:
- receiving a position of the spatially-aware projection pen in three-dimensional space from a position tracking mechanism;
receiving a signal indicating that a user interface menu has been activated through an input mechanism of the spatially-aware projection pen;
outputting the user interface menu as a projected image that is displayed on a display surface by a projector within the spatially-aware projection pen;
determining that a menu item specified by the user interface menu has been selected;
deactivating the function for displaying the user interface menu; and
configuring the spatially-aware projection pen for an operation based on the selected menu item.

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.

11. A computer-readable medium including instructions that, when executed by a processing unit within a spatially-aware projection pen, cause the spatially-aware projection pen to provide a user interface, by performing the steps of:
-
receiving a position of the spatially-aware projection pen in three-dimensional space from a position tracking mechanism; receiving a signal indicating that a user interface menu has been activated through an input mechanism of the spatially-aware projection pen; outputting the user interface menu as a projected image that is displayed on a display surface by a projector within the spatially-aware projection pen; determining that a menu item specified by the user interface menu has been selected; deactivating the function for displaying the user interface menu; and configuring the spatially-aware projection pen for an operation based on the selected menu item. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A spatially-aware projection pen configured to provide a user interface, comprising:
-
an enclosure that is configured to be grasped by a human hand and housing an input mechanism, a position tracking mechanism, a projector, and a processor, wherein the processor is configured to; receive an input signal indicating that display of a user interface menu is activated through the input mechanism of the spatially-aware projection pen, receive a position of the spatially-aware projection pen in three-dimensional space from the position tracking mechanism, output the user interface menu to a projected image that is displayed on a display surface by the projector within the spatially-aware projection pen, determine a menu item specified by the user interface menu is selected, deactivate the function for displaying the user interface menu, and configure the spatially-aware projection pen for an operation based on the selected menu item. - View Dependent Claims (22)
