Patent number: 8014040Abstract: A printer, scanner device and methods for using same are described herein. A printer device may include a dedicated input that, when actuated, generates and sends a request to a computer for known data or a predetermined print job, e.g., schedule information from a personal information management (PIM) application. A scanner device may include another dedicated input that, when actuated, automatically scans a document fed to the device by the user and sends the scanned image to IM (or other) software on a computer, bypassing the need to manipulate the scanned image using scanner software. The device may be used with printed metapaper, which includes a barcode or other indicia identifying the metapaper and corresponds to a stored template image of the metapaper. When the metapaper is rescanned, the scan can be compared to the stored template information to identify changes and synchronize the changes with the IM software.Type: GrantFiled: April 21, 2006Date of Patent: September 6, 2011Assignee: Microsoft CorporationInventors: Daniel Allen Rosenfeld, Robert Scott Dietz, Todd Haugen

Patent number: 8009915Abstract: In embodiments consistent with the subject matter of this disclosure, a user may input strokes as digital ink to a processing device. The processing device may partition the input strokes into multiple regions of strokes. A first recognizer and a second recognizer may score grammar objects included in regions and represented by chart entries. The scores may be converted to a converted score, which may have at least a near standard normal distribution. The processing device may present a recognition result based on highest converted scores according to a recurrence formula. The processing device may receive a correction hint with respect to misrecognized strokes and may add a penalty score with respect to chart entries representing grammar objects breaking the correction hint. Incremental recognition may be performed when a pause is detected during inputting of strokes.Type: GrantFiled: April 19, 2007Date of Patent: August 30, 2011Assignee: Microsoft CorporationInventors: Goran Predovic, Ahmad Abdulkader, Bodin Dresevic, Paul A. Viola, Milan Vukosavljevic

Patent number: 8009914Abstract: A method for classifying a handwritten input character is disclosed. Character models are used. Each character model is associated with an output character and defines a model specific segmentation scheme for that output character and an associated segment model. The model specific segmentation scheme defines a minimum length corresponding to a number of points in a stroke of the output character and a minimum length threshold. Using each of the character models, the input character is decomposed into segments and the segments are evaluated against the segment model of the respective character model to produce a score indicative of the conformity of the segments with the segment model. The character model that produced the highest score is selected and the input character is classified as the output character associated with the character model that produces the highest score.Type: GrantFiled: November 8, 2010Date of Patent: August 30, 2011Assignee: Silverbrook Research Pty LtdInventor: Jonathon Leigh Napper

Patent number: 8009916Abstract: Methods, systems and user interfaces for providing feedback to a user based on recognition of character-based ink input are provided. A first feedback is provided to the user to indicate a character as which ink input by the user is recognized. The first feedback is displayed in proximity to the displayed input ink so that the user knows to which ink character the first feedback corresponds. A second feedback may optionally also be provided indicating a correctness of the recognized ink input, as compared to a predefined correct value such as a correct word game solution or answer, by displaying the input ink in one format to indicate that the recognized value is correct, and by displaying the input ink in a second format to indicate that the recognized value is incorrect.Type: GrantFiled: September 8, 2006Date of Patent: August 30, 2011Assignee: Microsoft CorporationInventors: Todd Murray Landstad, Arin J.

Patent number: 8000531Abstract: A method of classifying a character string formed from a known number of hand-written characters is disclosed. The method starts by determining character probabilities for each hand-written character in the character string. Each character probability represents a likelihood of the respective hand-written character being a respective one of a plurality of predetermined characters. Each predetermined character has a respective character type. Character templates having the known number of characters are next identified. Each character template has a respective predetermined probability and represents a respective combination of character types. Character sequence probabilities corresponding to each of the character templates having the known number of characters are next determined. The character sequence probabilities are a function of the predetermined probability of the respective character template and the character probabilities of the hand-written character in the character string.Type: GrantFiled: December 22, 2010Date of Patent: August 16, 2011Assignee: Silverbrook Research Pty LtdInventor: Jonathon Leigh Napper
