TLDR
In this article, the pen subsystem examines the size of the user's writing to distinguish between gestures and handwriting, and the user may set the gesture versus text size according to his/her handwriting style.Abstract:
To distinguish between gestures and handwriting, the pen subsystem examines the size of the user's writing. The user may set the gesture versus text size according to his/her handwriting style. In this manner, the user knows exactly how large to make the gestures. If the user declines to customize the setting, the pen subsystem can query other user settings that indicate approximate size of the user's handwriting. A third choice available the system dynamically determine and track the size of handwriting. This would allow multiple users to serially use the computer without having to change settings.read more

Patent
Capture and display of annotations in paper and electronic documents
TL;DR: In this paper, a software and/or hardware facility that enables users to associate annotations with text segments contained in digital content is described. But the annotations are associated with a text segment, rather than the original content or an identifier associated with the original text segment was identified, annotations are applied to any content that utilizes the text segment in the future.

Automatically providing content associated with captured information, such as information captured in real-time
Martin T. King,Redwood Stephens,Claes-Fredrik Mannby,Jesse Peterson,Mark Sanvitale,Michael John Sebastian Smith,Christopher J. Daley-Watson +6 more
TL;DR: In this paper, a system and method for automatically providing content associated with captured information is described, in which the system receives input by a user, and automatically provides content or links to the information associated with the input.
Patent
Multi-touch input discrimination
TL;DR: In this article, techniques for identifying and discriminating between different types of contacts to a multi-touch touch-screen device are described, such as fingertips, thumbs, palms and cheeks, using patch eccentricity parameter.
Patent
Handheld device for capturing text from both a document printed on paper and a document displayed on a dynamic display device
TL;DR: In this paper, a device for capturing rendered text is described, which consists of one or more visual sensors that receive visual information as a part of capturing text, and a visual information disposition subsystem for disposing of visual information received by the visual sensors.
Patent
Data capture from rendered documents using handheld device
TL;DR: A portable device having scanning, imaging or other data-capture capability is described in this paper, where the portable device can indicate to the user when enough information has been captured to uniquely identify a source document.

TL;DR: An advanced user interface as mentioned in this paper allows a user to select among user-friendly input devices to operate any application program according to his individual preferences without change to the application program code without modifying the application code.
Patent
Method and apparatus for deducing user intent and providing computer implemented services
TL;DR: In this article, a method for deducing user intent and providing computer implemented services characterized by the steps of noticing a significant new event occurring within the computer system, deducing an intent from the significant new events and from the context in which the new event occurred, and providing a service based upon the new item and its context.

Method for deleting objects on a computer display
TL;DR: In this paper, a method for deleting objects displayed on the screen of a display assembly of a pointer based computer system is described, which includes the steps of detecting a pointer created stroke and processing the stroke for gesture recognition.
Patent
Recognition system and method for user inputs to a computer system
TL;DR: In this article, a technique for analyzing and interpreting user inputs to a computer, such as strokes, key depressions, or voice signals to a hand-held, pen-based computer system, is presented.
Patent
Method and apparatus for recognizing gestures on a computer system
TL;DR: In this paper, a stroke is input by a user onto a computer screen, and the stroke is smoothed by reducing the number of points that represent the stroke, and angles between adjacent segments of the smoothed stroke and derivatives of the angles are calculated.
