Pen-based interface for a notepad computer

Abstract

A notepad computer with a page display region displaying a page of a document on which a user can write using a pen or stylus type writing tool is provided. Associated with the page is an interface that can be used with the pen. The interface includes a core task tool region adjacent to the page where tool icons are partially visible until the pen is brought near one of the icons. The tool icon becomes fully visible when the pen is within the region of the icon. The tool when activated can pop-up a radial pop-up menu located at an edge of the document where all the menu choices are located in a semi-circle away from the edge so that the users hand while holding the pen and making a selection does not block the choices. A page flipping tool is located in a corner of the page and is an explicit two-stroke menu allowing selection of a next or previous page. A page scrolling tool is located along an edge of the page, the scrolling tool when activated is an implicit button allowing scrolling in one implied direction. The interface also includes a stack region adjacent to said page display region having one or more stack icons each representing a stack of documents. The icon is also an explicit two-stroke radial pop-up menu having forward and backward choices for selecting documents in the stack and a stack document list display displaying a list of documents in the stack when the stack icon is touched by an input pen. The interface also includes a typing tool overlaying a portion of the page and including a writing zone where a user handwrites strokes and, a page zone comprising part of the page where typed text corresponding to the handwritten strokes is displayed as the handwriting occurs.

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a divisional application of prior U.S. patent application Ser. No. 10 / 011,713, filed Dec. 11, 2001, which is a divisional application of prior U.S. application Ser. No. 09 / 196,100 filed Nov. 20, 1998 (now U.S. Pat. No. 6,337,698, issued Jan. 8, 2002), the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention is directed to a notepad or notebook computer interface that facilitates input via a pen and, more particularly, to a system that provides interface elements particularly suitable for pen-based input to, and interaction with, electronic documents. [0004] 2. Description of the Related Art [0005] Making electronic information as handy as paper requires an interaction model which is somewhat different than conventional systems. Documents, the primary form in which people obtain and produce information, are most familiar and ma...

AI Technical Summary

Benefits of technology

The present invention provides a user interface for a page display that allows for changing the behavior of the system in a pop-up mode without obscuring the page. The interface includes input menu pallets that consider the relation of the user's hand to the page and the side edge of the display. The interface also provides a page region designated for flipping the pages and allows for direct input on the page. The system allows for both converting handwriting to text and displaying converted text characters on the page during the writing. The interface includes a system where both the location and orientation of the pen act to determine its function. The interface also includes a stack region for selecting documents in a stack and a typing tool for overlaying a portion of the page and displaying typed text. Overall, the invention provides a more efficient and user-friendly interface for interacting with a page display.

Problems solved by technology

Additionally, the system must support text entry via the pen, but not let the conversion of pen input to text impede the perceived natural flow of events.
