Method for implementing a partial ink layer for a pen-based computing device
First Claim
1. A method of writing to a computing device using a touching device for data entry, comprising:
- a) locating a partial ink-layer over a region of a display screen, b) forming a cursive combination of characters by contacting a transparent touch screen located over said LCD screen with a touching device, c) displaying an ink trail of said touching device in said partial ink layer as said touching device forms said cursive combination of characters, e) storing a digital representation of said cursive combination of characters, f) erasing said ink trail after said touching device forms said cursive combination of characters.

Abstract
A method for creating an ink-trail and implementing a partial ink layer in a pen based computing apparatus is described. The partial ink layer, which is smaller than a display window of a computing apparatus, is located at a starting address with a shape and size that fits within the display widow. An ink trail is created within the ink layer that simulates ink flowing from the pen to paper while a character, or several cursive characters, is formed by the pen while touching a touch screen overlaying the display screen of the computing apparatus. The ink trail is erased when the pen is removed from the touch screen. The bit depth of the pixels in the partial ink layer are less than for the pixels of the main display and can be as few as 2, which includes a transparency bit.
