Publication number: 20190220139Abstract: 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: ApplicationFiled: March 25, 2019Publication date: July 18, 2019Applicant: Tactual Labs Co.Inventors: Ricardo Jorge Jota Costa, Clifton Forlines, Daniel Wigdor, Steven Leonard Sanders, Bruno Rodrigues De Araujo

Publication number: 20190220256Abstract: Disclosed are touch sensitive devices and methods of responding to hits in touch sensitive devices that include a graphical user interface having interface elements, each associated with a program element. A hit test map updater is used to process graphical user interface information into a hit test map in connection with the rendering of the graphical user interface, such that the hit test map associates properties with interface elements appearing on the graphical user interface. An input processor is used to receive a location corresponding to an input in connection with an input event, search the hit test map in which values are associated with interface elements appearing in the graphical user interface, and identify a property of the interface element from the values. In an embodiment, the identified property is proved to a central processing system and a user interface event is generated.Type: ApplicationFiled: March 22, 2019Publication date: July 18, 2019Applicant: Tactual Labs Co.Inventors: Bruno Rodrigues De Araujo, Jonathan Deber, Clifton Forlines, Ricardo Jorge Jota Costa, Daniel Wigdor

Publication number: 20190220145Abstract: In an embodiment, a touch surface, such as a GUI is graphically divided into two or more input regions, and based on this division, input event paths from a single sensor can be integrated within an operating system to provide application developers with the ability to easily and effectively filter there-between. The graphical division allows an application developer to specify which elements of a given GUI take one path, versus another. In an embodiment, low-latency and high-latency event paths are provided; an algorithm takes into consideration input regions and, based on those regions, handles the low- and high-latency input event paths in a computer system, directing the appropriate inputs through the appropriate processing, and directing the output to the appropriate process or queue without creating constraints on the low-latency event processing due to the presence of higher-latency event paths for a given sensor.Type: ApplicationFiled: March 25, 2019Publication date: July 18, 2019Applicant: Tactual Labs Co.Inventors: Bruno Rodrigues De Araujo, Ricardo Jorge Jota Costa, Clifton Forlines, Steven Leonard Sanders

Patent number: 10353515Abstract: 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: March 19, 2018Date of Patent: July 16, 2019Assignee: Tactual Labs Co.Inventors: Bruno Rodrigues De Araujo, David Holman, Ricardo Jorge Jota Costa, Braon Moseley

Publication number: 20180306568Abstract: A controller for sensing deformation including a sensor structure having a deformable conductor and another conductor (which may also be deformable). The deformable conductor may be made out of a flexible non-fluid material (e.g., rubber) or a conductive fluid. The deformable conductor may be deformed by the deformation of the sensor structure or by other forces. The sensor comprises circuitry to drive and sense signals on interacting pairs of conductors (the deformable conductor or the other conductor can act as the drive side, or as the sense side). Sense signals are processed to analyze deformation of the deformable conductor, and deformation of the sensor structure. Where the sensor is deployed proximate to human skin, deformation and changes in deformation may be used to correlate or infer a body position, movement or pose.Type: ApplicationFiled: April 2, 2018Publication date: October 25, 2018Applicant: Tactual Labs Co.Inventors: David Holman, Ricardo Jorge Jota Costa, David Clark Wilkinson, Bruno Rodrigues De Araujo, Adam Landa
