Apple gets three Multi-touch patents on 12 Oct 2010
US 7,812,826 has first claim:
A method, comprising: detecting at least two first contacts on a display surface of a multi-touch-sensitive display device; detecting a first motion associated with the at least two first contacts, wherein the first motion corresponds to a multi-touch gesture; adjusting a parameter of a graphical object in accordance with the first motion; detecting a breaking of the at least two first contacts; after detecting the breaking of the at least two first contacts, detecting at least two second contacts on the display surface; detecting a second motion associated with the at least two second contacts, wherein the second motion corresponds to the multi-touch gesture and the at least two second contacts are detected within a pre-determined time interval after the breaking of the at least two first contacts is detected; and continuing to adjust the parameter of the graphical object in accordance with the second motion.
Priority is claimed to a provisional application:
This application claims priority to U.S. Provisional Patent Application No. 60/755,366, filed Dec. 30, 2005, entitled "Portable Electronic Device with Multi-Touch Input," which application is incorporated by reference herein in its entirety.
US 7,812,828 has first claim:
A method of processing input from a touch-sensitive surface, the method comprising: receiving at least one proximity image representing a scan of a plurality of electrodes of the touch-sensitive surface; segmenting each proximity image into one or more pixel groups that indicate significant proximity, each pixel group representing proximity of a distinguishable hand part or other touch object on or near the touch-sensitive surface; and mathematically fitting an ellipse to at least one of the pixel groups.
The patent family of the '828: This application is a continuation of 11/015,434, entitled "Method and Apparatus for Integrating Manual Input," filed Dec. 17, 2004 now U.S. Pat. No. 7,339,580, which is a continuation of 09/236,513 (now Pat. No. 6,323,846) filed Jan. 25, 1999 which claims the benefit of provisional application 60/072,509, filed Jan. 26, 1998, each of which is hereby incorporated by reference in its entirety. This application is also related to Application Ser. No. 11/428,501, entitled "Capacitive Sensing Arrangement," 11/428,503, entitled "Touch Surface," 11/428,506, entitled "User Interface Gestures," 11/428,515, entitled "User Interface Gestures", 11/428,522, entitled "Identifying Contacts on a Touch Surface," 11/428,521, entitled "Identifying Contacts on a Touch Surface", 11/559,736, entitled "Multi-Touch Contact Tracking Algorithm", 11/559,763, "Multi-Touch Contact Motion Extraction," 11/559,799, entitled "Multi-Touch Contact Motion Extraction," 11/559,822, entitled "Multi-Touch Contact Motion Extraction," 11/559,833, entitled Multi-Touch Hand Position Offset Computation, each of which is hereby incorporated by reference in its entirety.
