  • Patent number: 12254135
    Abstract: Simulation of a physical interface utilizing touch tracking, force sensing, and haptic feedback is presented herein. A system tracks, via a touch sensing device of a tactile sensor of the system, a movement of a finger across the tactile sensor; in response to a location of the movement being determined to correspond to an interactive surface of the tactile sensor, the system generates, at the location, a first haptic feedback representing a defined type of simulated physical interface; based on the defined type of simulated physical interface, the system detects a force that has been applied to the tactile sensor; and in response to the force being determined to satisfy a defined force condition representing that an action is to be initiated, the system generates, via the interactive surface, a second haptic feedback representing that the action has been initiated by the system.

  • Publication number: 20240402816
    Abstract: One variation of a method for modifying haptic feedback response includes, during a set-up period: at a calibration system, applying a target selection force, to a target location on a surface of a touch sensor; at the touch sensor, triggering vibration cycles across haptic actuators to oscillate the touch sensor surface; capturing a haptic waveform representing oscillations at the first target location on the surface during the vibration cycles; interpreting a vibration cycle for the haptic actuators corresponding to a target haptic intensity at the target location based on the haptic waveform. The method also includes, during a deployment period, following the set-up period: detecting a force magnitude for a touch input applied proximal the target location on the surface; and in response to the force magnitude exceeding the target selection force, triggering the vibration cycle at the haptic actuators to oscillate the surface at the target haptic intensity.

    Abstract: Simulation of a physical interface utilizing touch tracking, force sensing, haptic feedback, and machine learning is presented herein. A system tracks, via a touch sensing device of a tactile sensor of the system, a movement of a finger across the tactile sensor; in response to a location of the movement being determined to correspond to an interactive surface of the tactile sensor, the system predicts a first haptic feedback representing a defined type of simulated physical interface; based on the defined type of simulated physical interface, the system detects a force that has been applied to the tactile sensor; and in response to the force being determined to satisfy a defined force condition representing that an action is to be initiated, the system predicts, via the interactive surface, a second haptic feedback representing that the action has been initiated by the system.

  • Patent number: 12079392
    Abstract: One variation of a method for modifying haptic feedback response includes, during a set-up period: at a calibration system, applying a target selection force, to a target location on a surface of a touch sensor; at the touch sensor, triggering vibration cycles across haptic actuators to oscillate the touch sensor surface; capturing a haptic waveform representing oscillations at the first target location on the surface during the vibration cycles; interpreting a vibration cycle for the haptic actuators corresponding to a target haptic intensity at the target location based on the haptic waveform. The method also includes, during a deployment period, following the set-up period: detecting a force magnitude for a touch input applied proximal the target location on the surface; and in response to the force magnitude exceeding the target selection force, triggering the vibration cycle at the haptic actuators to oscillate the surface at the target haptic intensity.

  • Patent number: 11954285
    Abstract: One variation of a method for detecting an input at a touch sensor—including a force-sensitive layer exhibiting variations in local resistance responsive to local variations in applied force on a touch sensor surface and a set of drive and sense electrodes—includes: driving a drive electrode with a drive signal; reading a sense signal from a sense electrode; detecting a alternating-current component and a direct-current component of the sense signal; in response to a magnitude of the direct-current component of the sense signal falling below a threshold magnitude, detecting an input on the touch sensor surface during the scan cycle based on the alternating-current component of the sense signal; and, in response to the magnitude of the direct-current component of the sense signal exceeding the threshold magnitude, detecting the input on the touch sensor surface during the scan cycle based on the direct-current component of the sense signal.
