Patent number: 8884905Abstract: A handwriting recognition apparatus facilitates user entry of strokes one on top of another. The apparatus, which includes a processor and a display integrated with a touch sensitive screen, receives a series of strokes via the screen. Each stroke is defined by contact, trace, and lift occurrences. Each stroke appears on the display until occurrence of a prescribed event, and then disappears. The apparatus accumulates strokes into a buffer and interprets all accumulated strokes collectively against a character database and optionally a linguistic database, to identify multiple candidate strings that could be represented by the accumulated strokes. The apparatus displays candidate strings for user selection after all strokes have faded, or after receiving a user submitted delimiter, or after a given delay has elapsed following user entry of the latest stroke. Alternatively, candidate strings are displayed after each stroke without waiting for timeout or explicit delimiter.Type: GrantFiled: October 12, 2012Date of Patent: November 11, 2014Assignee: Nuance Communications Inc.Inventors: Jonas Morwig, Jonas Andersson

When a pointer is positioned in the proximity of (but not in contact with) the detection sensor or when a pressure applied to the detection sensor by the pointer in contact with the detection sensor is equal to or lower than a threshold, detection signals corresponding to variation in electrostatic capacity between the first and second conductors are supplied.Type: GrantFiled: October 21, 2010Date of Patent: June 10, 2014Assignee: Wacom Co., Ltd.Inventors: Yasuo Oda, Sadao Yamamoto, Yoshihisa Sugiyama

Patent number: 8749497Abstract: Multi-touch shape drawing. The use of multi-touch gesture detection improves the user interface experience associated with generating and modifying shapes. By associating unique multi-touch gestures with the generation of corresponding shapes, the accuracy and ease of use with which shapes can be generated can be improved. By associating multi-touch gestures with the modification of shapes, the ease of use with which shapes can be modified can be improved.Type: GrantFiled: December 12, 2008Date of Patent: June 10, 2014Assignee: Apple Inc.Inventor: John Greer Elias

Patent number: 8743062Abstract: A touch controller having noise reduction circuitry is disclosed. The touch controller can include a transmit section for generating stimulation signals to drive a touch display to sense a touch or hover event. The touch controller can also include a receive section for processing touch signals from the touch display indicative of the touch or hover event. The touch controller can reduce noise introduced into the stimulation signals and propagated through the touch display into the touch signals, thereby interfering with touch and hover sensing. To reduce the noise, the transmit section's noise reduction circuitry can isolate and subtract some or all of the noise from the stimulation signals. In addition or alternatively, the receive section's noise reduction circuitry can isolate and subtract some or all of the noise from the touch signals.Type: GrantFiled: December 3, 2010Date of Patent: June 3, 2014Assignee: Apple Inc.Inventors: Christoph Horst Krah, Ali Motamed

Patent number: 8729411Abstract: When a user holds an optical scanning device to scan a micro dotmap on a displaying medium, a coordinate of a frame center of a retrieved frame on the displaying medium is calculated according to a decoding method for the micro dotmap in advance. A moving vector corresponding to a difference between difference frames scanned by the optical scanning device at different moments is calculated so that an instant location of the frame center on the displaying medium can be calculated anytime. Therefore, a large number of calculations brought by frequent decoding may be saved since merely a few calculations are required in calculating the moving vector. By further decoding the coordinate of the frame center at moments spaced with constant or variable intervals, errors brought by vibrations of the displaying medium are instantly fixed. Accumulated errors are avoided in the calculated instant locations of the frame center anytime.Type: GrantFiled: July 15, 2013Date of Patent: May 20, 2014Assignee: PixArt Imaging Inc.Inventor: Shou-Te Wei

Patent number: 8730169Abstract: The present invention discloses a hybrid pointing device including an optical navigation module and a pointing module. The optical navigation module is configured to replace the conventional buttons of a convention pointing device, such as an optical mouse or a trackball mouse. The optical navigation module is configured to sense gestures of at least one object operated by a user to activate commands associated with particular programs running on the host. Since the optical navigation module is only configured to sense gestures of the object but not the movement of the hybrid pointing device relative to a surface, the resolution thereof is aimed to be sufficiently high enough for sensing gestures and no need to be relatively high.Type: GrantFiled: April 30, 2010Date of Patent: May 20, 2014Assignee: Pixart Imaging Inc.Inventors: Cho Yi Lin, Yen Min Chang, Yao Ching Hsu, Yi Hsien Ko
