Patent number: 11029843Abstract: A touch sensitive keyboard is disclosed. In one embodiment, a touch sensitive keyboard is provided that has a touchpad area separate from the keyboard keys. The keyboard is configured to disabled touchpad sensitivity when certain touch signals are received. In another embodiment, a touch sensitive keyboard is used as a controller. In a controller mode, keys on a touch sensitive keyboard are adapted to output a signal strength corresponding to a distance between the key and a finger operating as a control. In an embodiment, a touch sensitive keyboard includes a processor adapted to output a keystroke in response to one of the plurality of touch sensitive keys being pressed, and to output one or more touch points determined by interpolating signal strength for each of the plurality of touch sensitive keys on the keyboard.Type: GrantFiled: September 15, 2017Date of Patent: June 8, 2021Assignee: Tactual Labs Co.Inventors: Clifton Forlines, David Holman, Stephen Dennis, Ricardo Jorge Jota Costa, Steven Leonard Sanders, David Clark Wilkinson, Braon Moseley, Bruno Rodrigues De Araujo

Patent number: 10928180Abstract: 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: GrantFiled: April 2, 2018Date of Patent: February 23, 2021Assignee: Tactual Labs Co.Inventors: David Holman, Ricardo Jorge Jota Costa, David Clark Wilkinson, Bruno Rodrigues De Araujo, Adam Landa
