Computer users may integrate any annotation, including ink, highlighter, text-based notes and audio, directly into a Web-based document (WBD) displayed by a Web browser. This integration enables others to view the personalized annotated WBD, which retains its original active links and properties, over the Internet without the need for specialized software. Annotations are integrated into WBDs by freezing the WBD, overlaying an image file containing the annotations onto the WBD, and enabling browser events to pass through the image layer. Annotations may also be integrated into WBDs by using component object technology. By collecting and organizing annotated WBDs, users can be provided with an intuitive Web-based interface for accessing, viewing and searching the annotated WBDs. Users may annotate blank WBDs, effectively converting their Web browsers into online notebooks/scrapbooks. Users may also be provided with many interface techniques, such as dog-ears and its associated navigation tools, splitting pages, turning pages, selecting and copying various portions of a WBD (including shaking out a copy), and marking menus suited for right-handed or left-handed users.

System and method for annotating web-based document

A software and/or hardware facility that enables users to associate annotations with text segments contained in digital content. A capture client allows users to create annotations associated with text segments on content being viewed by the user. The annotations are stored in association with the text segments by an annotation server. When a user subsequently views content, text fragments in the viewed content are compared with the stored text segments by the facility. Text segments that are found to match the text fragments are identified by the facility, and the associated annotations displayed to the user on the viewed content by a display client. Because stored annotations are associated with a text segment, rather than the original content or an identifier associated with the original content from which the text segment was identified, annotations are able to be applied to any content that utilizes the text segment in the future.

Capture and display of annotations in paper and electronic documents

A system and method for automatically providing content associated with captured information is described. In some examples, the system receives input by a user, and automatically provides content or links to content associated with the input. In some examples, the system receives input via text entry or by capturing text from a rendered document, such as a printed document, an object, an audio stream, and so on.

Automatically providing content associated with captured information, such as information captured in real-time

Techniques for identifying and discriminating between different types of contacts to a multi-touch touch-screen device are described. Illustrative contact types include fingertips, thumbs, palms and cheeks. By way of example, thumb contacts may be distinguished from fingertip contacts using a patch eccentricity parameter. In addition, by non-linearly deemphasizing pixels in a touch-surface image, a reliable means of distinguishing between large objects (e.g., palms) from smaller objects (e.g., fingertips, thumbs and a stylus) is described.

Multi-touch input discrimination

A device for capturing rendered text is described. The device incorporates one or more visual sensors that receive visual information as a part of capturing rendered text. The visual sensors are collectively capable of capturing both text that is permanently printed on a page, and text that is displayed transitorily on a dynamic device. The device further incorporates a visual information disposition subsystem for disposing of visual information received by the visual sensors. The device further incorporates a package that bears the visual sensors and the visual information disposition subsystem, and is suitable to be held in a human hand.

Pre-recognition analysis on stroke characteristics such as the count, size and position of each stroke in real-time as it is drawn improves recognition accuracy. After each stroke, the set of strokes is weighted toward handwriting or gesture. The system uses a gesture threshold size to distinguish between gestures and handwriting. The system also uses the stroke count to distinguish between the two inputs, relying on the knowledge of the allowable number of strokes in a gesture. The count information may also be used in conjunction with the stroke size information to weight the set of strokes between gestures handwriting. Once the stroke size crosses a gesture vs. text size threshold, the result is weighted toward gestures. By examining the `white space` between strokes and the juxtaposition of the strokes, a gesture vs. text determination can be made with high accuracy.

Distinguishing gestures from handwriting in a pen based computer by stroke analysis

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.

Distinguishing gestures from handwriting in a pen based computer by size discrimination

A method of and system for facilitating stylus input into a text entry field in a pen-based computer system. The system detects a touch down of a stylus and determines whether the touch down is in a text entry field. Upon detection of movement of the stylus in the text entry field greater than a threshold, the system draws an include rectangle around the text entry field. The system sizes the include rectangle based on the size of the text entry field. The system interprets and completely inks any stroke of the stylus starting within the include rectangle within a predetermined timeout as an input to the text entry field. The system erases the include rectangle whenever it detects a stylus touch down outside the include rectangle, or the predetermined timeout expires without the system detecting a stylus touch down.

A method of and system for facilitating stylus input into a text entry field in a pen-based computer system. The system detects a touch down of a stylus and determines whether the touch down is in a text entry field 65. Upon detection of movement of the stylus in the text entry field greater than a threshold, the system draws an include round the text entry field. The system sizes the include rectangle based on the size of the text entry field. The system interprets and completely inks any stroke of the stylus starting within the include rectangle within a predetermined timeout as an input to the text entry field. The system erases the include rectangle whenever it detects a stylus touch down outside the include rectangle, or the predetermined timeout expires without the system detecting a stylus touch down.

Method and system for facilitating user input into a GUI window using a stylus

PROBLEM TO BE SOLVED: To provide the method and system which facilitates stylus input to a text field as to a computer system which makes good use of a pen. SOLUTION: When touch-down movement of a stylus is detected in a text entry field 63, etc., which is larger than a specific threshold value, a panel 67 is drawn at the periphery of the text entry field and on the basis of the text entry field, the size of the panel is set. The stroke of the stylus which is started within the panel before a specific timeout is interpreted to paint ink. When no touch-down movement of the stylus is detected before the specific timeout, the panel is erased.
