What is Tactile Touch?

Tactile Touch, created by the MicroTouch™ Capacitive TouchSense® System, makes virtual on-screen buttons feel real.

It supplies tactile feedback in response to a user’s touch, creating a more intuitive, engaging and natural experience for the player.

With this system, a variety of touch-initiated tactile effects can be synchronized with audio and visual prompts, supplying game developers with a new set of interactive tools for greater creativity.

How Tactile Touch Works

Tactile system utilizes lateral (X or Y) movement of the touch screen when touched (Z-Axis not supported)

Small displacement (<0.020”) with high acceleration causes skin on finger to stretch

Integrations are insensitive to finger pressure causing consistent tactile effects

Tactile System Integration

3M Touch Systems


Tactile System Integration - Overall LCD housing needs to be rigid to be able to transmit actuator forces Actuators can be mounted on the sides or rear of LCD Qty of actuators per system depend on total weight of touch screen

and carrier/s, each actuator is capable of moving 300-400 grams. Carrier/carriers provide the mechanical coupling from actuators to

touch screen. carriers must have sufficient stiffness, thickness & material composition to transmit actuator forces

Touch screen is mounted to carrier/carriers which is then mounted to actuators. Tactile system “floats” above the LCD.

Seal between touch screen and front bezel Level of sealing will depend on each individual integration and allowable bezel

foam compression Bezel foam compression effects tactile output

14

3M Touch Systems


Tactile System Integration - Actuators Actuators are designed for 300 to 400 grams per actuator (non-

sealed system) Systems with 4 actuators must not exceed 1600 grams System is comprised of touch screen and carriers System sealing will apply both a resistance and damping forces and need to be

taken into consideration for acceptable tactile response Systems with less mass will have stronger tactile effects & visa versa Controller can accept up to 8 actuators

Actuators must be aligned/actuated in same direction Actuators are wired in parallel from the controller but have no polarity Actuators in system must be balanced before completing integration

Loosen screws that hold carriers to actuators, apply 12-16 VDC to all actuators at same time, tighten screws

Tactile System Integration – LCD/Touchscreen Seal

Seal between LCD and touch screen is achieved utilizing Delrin (0.010” thick) slides that are adhered to LCD and are

between LCD and carriers. Delrin slides are parallel to direction of tactile movement. Delrin is adhered to LCD with 3M 468MP.

Bisco BF1000 (0.125” thick) foam that is adhered to LCD and is perpendicular to carriers as well as direction of tactile movement. Adhesive on foam is supplied by manufacturer and is single sided.

Adhering foam & Delrin to LCD facilitates easy removal of touch screen & carrier assembly

Tactile System Integration - Considerations

24VDC and ~1.25 amp/actuator (4 actuator system ~= 5 amps)

Sealing requirements will impact tactile system, need to plan ahead by evaluating entire system with appropriate level of sealing Bisco BF1000 (open cell foam) at 1/8” and ¼” thick have

worked well. Acceptable compression levels should be no more than 25% of the gasket

Customers will need to determine appropriate sealing for their application

18

Gasket Stack Up

Always mount Delrin parallel to movement of Actuators.

Mount Delrin only to LCD, 1 layer is all that is needed.

Do not compress the touch screen down on the LCD.

Allow smooth movement of the touch system over the LCD

Tail Considerations

Tail should run parallel to the actuator movement

Minimize stress on the tail, add loop

Do not run tail near backlight inverter

Avoid creasing tail near the connector
