  • Patent number: 6487569
    Abstract: A notes organizer program is provided that allows a user to organize notes on a limited resource computing device. The notes are organized by associating a note, if desired, with a project. The user can name or rename a note or a project. If the user does not specify a note name, the notes organizer program determines the note name based on the associated project. If there is no associated project, the note name is based on the type of note (e.g., voice, handwritten, etc.). A template project is provided for creating notes from templates.

  • Patent number: 6396505
    Abstract: Display apparatus, and methods for displaying images, e.g., text, on gray scale and color monitors where each pixel includes multiple pixel sub-components are described. Filtering and/or displaced sampling is used to generate pixel sub-component luminous intensity values. As a result of treating pixel sub-components as distinct light emitters corresponding to different image portions, resolution is enhanced but color errors may be introduced into the image being displayed. Various techniques for detecting noticeable and/or distracting color errors are described. In addition, various techniques for correcting, compensating for, or reducing color errors are described. In one particular embodiment, red, green and blue pixel sub-component luminous intensity values are examined and compared to a range of luminous intensity values which is determined as a function of utilized foreground and background pixel colors.

  • Publication number: 20020059350
    Abstract: A computer system and method for providing user feedback when creating, modifying, or editing electronic documents. An insertion point icon is placed in a document at a position for insertion and/or deletion of text, graphics, data, etc. Upon receiving an user input indicating movement, the insertion point icon is divided into two icons, one stationary at the position, and one moving with user input. When movement is complete, space contained between the icons may be deleted or inserted. The system may be used to shift handwritten text to subsequent lines on an electronic document containing handwritten text, and may be used to bring two groups of text together, deleting space in between. A connection line may be displayed between the icons to provide feedback regarding the action to be taken.

  • Publication number: 20020057836
    Abstract: A logical separation between pages, such as an implicit page break, is introduced to separate text entered during one handwriting session from text entered during another handwriting session. If the user leaves more than a threshold amount of blank space at the bottom of the page immediately preceding the new page, then an implicit page break may be inserted at the beginning of the new page. The amount of blank space left at the end of the preceding page may be combined with other criteria to determine whether to insert an implicit page break. The amount of time elapsed since ink has been captured on the previous page is another factor that may be used by itself or combined with other factors to determine whether to insert an implicit page break into the new page. A change in context, such as a different date or different recognized subject matter labels, is also a factor that may be considered in determining whether to insert an implicit page break.

  • Publication number: 20020056575
    Abstract: The present invention relates to a system, method and medium for receiving and acting upon user input. In one embodiment, the user may only have access to a limited input device, like a stylus. Using the present invention, a user is provided with intuitive responses from the system based on inputs from the limited input device.

  • Publication number: 20020049787
    Abstract: Methods for classifying, anchoring, and transforming ink are disclosed. Ink drawings and ink annotations are captured and stored with additional information that allows the various described methods to associate the ink with one or more displayed elements. During reformatting or re-flowing a displayed document, the ink may be properly displayed as originally intended.

  • Publication number: 20020011993
    Abstract: A method and system for automatically determining when an application should switch from a writing mode to a text entry mode, and vice-versa. When a soft input panel (SIP) or input method (IM) is selected, the application is notified and enters a text entry mode. Inputting via the IM while in this mode causes a character to be sent to the application, while pen events in the application window enable text editing and the selection of text and ink data in the application widow. When the SIP is deselected, the application is notified and enters a pen (writing) mode, whereby the pen events are interpreted as digital ink strokes instead of characters. Sub-modes of the pen mode are also available, via which the pen events are used to manipulate existing ink in the application window. Visual feedback may be provided to remind the user of the current mode and/or sub-mode.

  • Patent number: 6339426
    Abstract: The resolution of text rendered on a display device having sub-pixel elements, such as an RGB LCD for example, and in particular, on a display device having horizontal striping is enhanced by (i) overscaling (or oversampling) character outline information in the vertical (or Y) direction, and (ii) filtering displaced information from the overscaled (or oversampled) character outline information. Metrics associated with character outline information may be appropriately adjusted. The vertical (or Y) position of the baseline of adjacent characters may be constrained by forcing the first pixel above the baseline to be composed of a full number N of scan conversion source samples, where N corresponds to an overscaling (or oversampling) factor. Groups of scan conversion source samples may be converted into packed pixel index values. Color values may be selectively filtered when the differences in the intensity of adjacent sub-pixel elements would otherwise be irritating to view.

  • Patent number: 6256009
    Abstract: A method for automatically and intelligently scrolling handwritten ink entered into a computer device. The method detects when the user is on the last available line for writing, and starts a timer on each pen-up event or resets the timer on a pen-down event. An automatic scroll is performed after the writing on the last line has halted for more than a threshold amount of time. The threshold time may be variable based on criteria, such as the x-coordinate of the last writing, the writing speed of the user, the last character that was written, and the current zoom percentage of the display. The zoom percentage may also be used to determine the number of lines to scroll. New ink written after the automatic scrolling operation may be moved up to the scrolled ink, if the method determines that the user intended to write the new ink directly after the scrolled ink.
