Method of making and using a tactile array device

A device for communicating a physical touch comprising:

• an array of pistons numbering greater than 25 per square inch, each piston having a contact surface;
• an actuator array to independently move each piston;
• a controller to determine a depth position of each piston in the array of pistons;
• and
• a membrane disposed over the contact surface of each of the pistons, wherein said membrane comprises a piezo electric device,
• wherein each of the pistons comprises a cylinder and a pin disposed in the cylinder.

A device for communicating a physical touch comprising:

• an array of pistons numbering greater than 25 per square inch, each piston having a contact surface;
• an actuator array to independently move each piston;
• a controller to determine a depth position of each piston in the array of pistons;
• and
• a sensor for a moisture feedback and compensation,
• wherein each of the pistons comprises a cylinder and a pin disposed in the cylinder.

A process for communicating the sense of touch between two devices comprising:

• providing a primary device comprising an array of primary pistons and an array of primary valves, wherein the primary pistons are independently movable and have a density greater than 25 pistons per inch squared;
• providing a secondary device comprising an array of secondary pistons and an array of secondary valves, wherein the secondary pistons are independently movable;
• detecting a position of each primary piston;
• transmitting each primary piston's position to the secondary device;
• manipulating each secondary valve on the secondary device to achieve a matching equilibrium between each primary piston's position and a corresponding secondary piston's position;
• detecting a position of each secondary piston;
• transmitting each secondary piston's position to the primary device;
• and
• manipulating each primary valve on the primary device to achieve a matching equilibrium between each primary piston's position and a corresponding secondary piston's position.
