METHOD FOR INTERACTING WITH A DYNAMIC TACTILE INTERFACE

摘要

A method for registering user interaction with a dynamic tactile interface, which includes a tactile layer defining a tactile surface, a deformable region, and a peripheral region and coupled to a substrate opposite the tactile surface, the deformable region cooperating with the substrate to form a variable volume. The method includes detecting a first contact of an object at a first location on the tactile surface at a sensor; detecting a removal of the object from the first location; at a first time, detecting a first pressure of the variable volume at a pressure sensor; at the sensor, at a second time after the first time, detecting a second contact at a second location; at the second time, detecting a second pressure at the pressure sensor; interpreting the first and second contact, and the pressure difference as a gesture; and executing a command corresponding to the gesture.

1. A method for registering user interaction with a dynamic tactile interface comprising a tactile layer and a substrate, the tactile layer defining a tactile surface, a deformable region, and a peripheral region adjacent the deformable region and coupled to the substrate opposite the tactile surface, the deformable region cooperating with the substrate to form a variable volume filled with a mass of fluid, the method comprising:
at a sensor coupled to the substrate, detecting a first contact of an object at a first location on the tactile surface; detecting a transition of the object along the tactile surface from the first location at a first time to a second location adjacent the deformable region at a second time; substantially at the first time, detecting a first pressure of the mass of fluid at a remote pressure sensor fluidly coupled to the variable volume; substantially at the second time, detecting a second pressure of the mass of fluid at the remote pressure sensor; in response to a pressure difference between the first pressure and the second pressure, interpreting the transition as a gesture; and in response to the gesture, executing a command corresponding to the gesture at a processor.
