Patent number: 12254135Abstract: 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.Type: GrantFiled: March 28, 2023Date of Patent: March 18, 2025Assignee: Sensel, Inc.Inventors: Vijay Rajanna, Darren Lochun, Ilya Daniel Rosenberg, Tomer Moscovich

Publication number: 20240402816Abstract: 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.Type: ApplicationFiled: August 8, 2024Publication date: December 5, 2024Inventors: Ninad Sathe, Vijay Rajanna, Ilya Daniel Rosenberg
