Patent number: 10620746Abstract: In an embodiment, a touch sensitive device includes a touch interface having rows and columns and a signal generator for generating unique orthogonal signals on a plurality of the rows, respectively. A touch processor identifies touch on the touch interface by processing touch signals present on the columns, and outputting a stream of touch events. A decimator receives the stream of touch events, selectively identifies one or more of the touch events in the stream and assembles information concerning one or more touch events in the stream, and outputs both the selectively identified touch events and the assembled information for use by the touch sensitive device.Type: GrantFiled: March 25, 2019Date of Patent: April 14, 2020Assignee: Tactual Labs Co.Inventors: Ricardo Jorge Jota Costa, Clifton Forlines, Daniel Wigdor, Steven Leonard Sanders, Bruno Rodrigues De Araujo

Patent number: 10620739Abstract: Disclosed are a method and corresponding touch sensitive device that detects touch and provides tactile feedback. In an embodiment, the device includes a touch interface having row conductors and column conductors. A first row signal generator transmits a first row signal on a first row conductor. A second row signal generator transmits a second row signal on a second row conductor, the second row signal being orthogonal to the first row signal. A third row signal generator generates an electrotactile discharge signal on at least one of the row conductors. In an embodiment, the electrotactile discharge signal is time multiplexed with at least one of said first row signal or said second row signal. A touch processor identifies a touch event on the touch interface by processing signals present on at least one of the column conductors.Type: GrantFiled: February 29, 2016Date of Patent: April 14, 2020Assignee: Tactual Labs Co.Inventor: Ricardo Jorge Jota Costa

Patent number: 10592049Abstract: A system and method are disclosed for using a touch sensing system capable of sensing location of a finger or object above a touch surface to inform a touch response system in an electronic device of a predicted future user input event or motion data in advance of an actual touch event. Current user input is sensed via the touch sensing system and data reflecting hover information is created. A model of user interaction with a touch surface is applied to the data representative of the user input to create data reflecting a prediction of a future user input event. In an embodiment, prior to occurrence of the predicted user input event, a predicted location and a predicted time at which the predicted future user input event will occur are provided to a touch response system.Type: GrantFiled: June 14, 2018Date of Patent: March 17, 2020Assignee: Tactual Labs Co.Inventors: Clifton Forlines, Ricardo Jorge Jota Costa, Daniel Wigdor, Karan Singh, Haijun Xia

Patent number: 10558296Abstract: Disclosed is a touch-sensitive controller system employing a controller comprising a plurality of separate FMT sensor patterns adapted to detect a variety positions of the human hand. The controller system outputs both touch events as well as data reflective of the hand interaction with the controller. The FMT sensors may be driven by a common signal generator, and can look at body-generate crosstalk to aid in understanding the position, orientation and grip of a hand on the controller. In an embodiment, signal injection can supplement FMT sensor data. Fusion among the data transmitted and received by the plurality of FMT sensors and additional injected signals may provide improved fidelity in both touch and hand modeling.Type: GrantFiled: July 15, 2019Date of Patent: February 11, 2020Assignee: Tactual Labs Co.Inventors: Bruno Rodrigues De Araujo, David Holman, Ricardo Jorge Jota Costa, Braon Moseley

Publication number: 20200012946Abstract: A method for classifying a gesture made in proximity to a touch interface. A system receives data related to the position and/or movement of hand. The data is delimited by identifying a variable length window of touch frames. The variable length window of touch frames is selected to include touch frames indicative of feature data. The variable length window of touch frames is classified based upon classifications learned by the classifying module to identify gestures.Type: ApplicationFiled: July 6, 2018Publication date: January 9, 2020Applicant: Tactual Labs Co.Inventors: Ricardo Jorge Jota Costa, Clifton Forlines
