Patent number: 8797579Abstract: 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: February 3, 2012Date of Patent: August 5, 2014Assignee: Microsoft CorporationInventors: Daniel Allen Rosenfeld, Kumar H.

Patent number: 8781230Abstract: Video-based handwriting input for biometric signature data collection is provided. The invention is implemented by finding all of the relative positions among all light points of light sources when all light sources mounted on a stylus are turned ON. An image is captured including effective strokes and digital data of pen pressure with a digital camera when a user writes on a writing surface with a stylus having a light source indicating x-y coordinates of strokes. The images are time-stamped. The stylus includes a micro-switch. When the stylus touches the writing surface, the micro-switch is turned on to let the light source indicating x-y coordinates of strokes turn ON and generate a light point. Effective stroke images and digital data of pen pressure are extracted by comparing the captured images with the light point on the stylus.Type: GrantFiled: November 13, 2007Date of Patent: July 15, 2014Assignee: International Business Machines CorporationInventor: Kelvin Shieh

Publication number: 20140177961Abstract: A handwritten-information processing apparatus includes a handwritten-information acquisition unit and a handwritten-information insertion unit. The handwritten-information acquisition unit acquires a handwritten information item which has been handwritten by a user on a medium having a region inside a writing frame and a region outside the writing frame. The region inside the writing frame includes division regions. The region outside the writing frame is located outside the region inside the writing frame. When the handwritten-information acquisition unit has acquired an insertion mark which is a handwritten information item extending across a boundary between the region inside the writing frame and the region outside the writing frame, the handwritten-information insertion unit inserts, on the basis of the insertion mark, into the region inside the writing frame, a handwritten information item which has been handwritten in the region outside the writing frame.Type: ApplicationFiled: June 6, 2013Publication date: June 26, 2014Inventor: Hideto ODA

Patent number: 8761513Abstract: The present invention is related to systems and methods for translating language text on a mobile camera device offline without access to the Internet. More specifically, the present invention relates to systems and methods for displaying text of a first language and a translation of the first language text into a second language text which is displayed in real time in augmented reality on the mobile device. The processing can use a single line or a multiline algorithm designed with a plurality of processing innovations to insure accurate real-time translations without motion jitter. The invention may be used to help travelers in a foreign country with difficulties in reading and understanding text written in the local language of that country. The present invention may be utilized with wearable computers or glasses, producing seamless augmented reality foreign language translations. Some embodiments are particularly useful in translations from Asian languages to English.Type: GrantFiled: March 12, 2014Date of Patent: June 24, 2014Assignee: Translate Abroad, Inc.Inventors: Ryan Leon Rogowski, Huan-Yu Wu, Kevin Anthony Clark

Publication number: 20140169676Abstract: An information processing apparatus includes a morphological analysis unit, a feature-value vector generation unit, and a degree-of-certainty calculation unit. The morphological analysis unit performs morphological analysis on a character recognition result. The feature-value vector generation unit generates a feature-value vector having elements, the number of which is P+1, for each character in the character recognition result. The feature-value vector includes part-of-speech likelihoods and a character similarity for the character in the character recognition result. The part-of-speech likelihoods correspond to P types of part of speech and are generated based on a probability of a part of speech of a word which includes the character and which is the result of the morphological analysis performed by the morphological analysis unit.Type: ApplicationFiled: May 14, 2013Publication date: June 19, 2014Applicant: FUJI XEROX CO., LTD.Inventor: Eiichi TANAKA

Patent number: 8755604Abstract: A system and method may include a processor that groups the glyphs of a document into font character models. OCR processing may be performed to identify the ASCII value of the font character models, with the results mapped to the glyphs contained with those models, thereby identifying the text of the original document. This results in fewer calls to an OCR engine, thereby providing a significant speedup. Further, when a model is assigned differing text values by the OCR engine, the system and method may identify the value most likely to be correct, thereby improving the accuracy of the output text.Type: GrantFiled: June 5, 2009Date of Patent: June 17, 2014Assignee: CVISION Technologies, Inc.Inventors: Ari David Gross, Raphael Meyers, Navdeep Tinna, Yunhao Shi
