1. A method for using an optical pen, comprising:
- when a tip of a stylus is in contact with a location of an image on a surface, employing three or more line of sight light detectors on the optical pen to separately detect reflected light from three points around the location, wherein the three or more line of sight light detectors are positioned at angular locations offset along the directional orientation of the stylus formed by the tip, and wherein the detected reflected light is provided by one or more remotely located light sources that are separate from the optical pen;
employing the detected lights from line of sight detectors to determine a position and an orientation of the tip of the stylus and the location on the surface;
storing information for the position, orientation and location; and
modifying the image based on the stored information.

Abstract
A method, apparatus, and manufacture for writing and annotation is provided. An image is provided on a surface. In one embodiment, each time invisible ink is deposited on the surface, the location of the invisible ink deposited on the surface is detected before the invisible ink vanishes from the surface. In another embodiment, when a tip of a stylus is in contact with a location of an image on the surface, employing three or more light detectors to detect light at the location. The detected light is employed to determine a position and an orientation of the tip of the stylus and the location on the surface, and modifying the image based on the stored information.

8. An optical pen for editing an image, comprising:
a stylus, further comprising; three or more line of sight light detectors arranged around a tip, wherein the tip is arranged to touch the image on a surface; and a hardware processor that is arranged to performs actions, including; when a tip of a stylus is in contact with a location of an image on a surface, employing the three or more line of sight light detectors on the optical pen to separately detect reflected light from three points around the location, wherein the three or more line of sight light detectors are positioned at angular locations offset along the directional orientation of the stylus formed by the tip, and wherein the detected reflected light is provided by one or more remotely located light sources that are separate from the optical pen; employing the detected lights from line of sight detectors to determine a position and an orientation of the tip of the stylus and the location on the surface; storing information in the hardware memory for the position, orientation and location of the stylus tip; and modifying the image based on the stored information. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A processor-readable non-transitive storage media that is operative to store data and instructions, which, when executed by one or more processors, enables actions with an optical pen, comprising:
-
when a tip of a stylus is in contact with a location of an image on a surface, employing three or more line of sight light detectors on the optical pen to separately detect reflected light from three points around the location, wherein the three or more line of sight light detectors are positioned at angular locations offset along the directional orientation of the stylus formed by the tip; employing the detected lights from line of sight detectors to determine a position and an orientation of the tip of the stylus and the location on the surface; storing information for the position, orientation and location; and modifying the image based on the stored information. - View Dependent Claims (16, 17, 18)
