“TwoTouch: When there’s no room for errors”

    Our Two Touch Redundancy Technology sees a second, resistive screen installed underneath the first, capacitive contact screen. Through this, a touch is registered on each screen separately and verified on both screens combined.

    In this way, the user is certain that a touch is only registered when it is certain, desired and is meant to trigger an action.


    TwoTouch Redundant Technology eliminates an important disadvantage for capacitive touchscreens in critical conditions: the touchscreen’s involuntary activation through minimal unintentional pressure, strong fluctuations in temperature or the close proximity of conductive materials.


    • Extremely high operational reliability
    • Safety in critical applications
    • High quality
    • Long lifecycle
    • Aesthetic design
    • Stable operation in fluctuating temperatures
    • Less significant impact of environmental conditions
    • The possibility of having one operational screen when the other is broken (reliability)

    The TwoTouch Redundant Technology makes the following applications possible:

    • MAXIMUM SAFETY (Redundancy): Combining the signals of both technologies increases safety because both screens have to transmit the same touch coordinate before it is validated. No chance on false touches or accidental Touch. Think of medical procedures in which a drop of blood may not activate the screen, military and industrial situations in which a slight, unintentional touch can have big consequences.


    • SAFETY BACKUP: Increased reliability because of the possibility to have one of the screens operational if the other is no longer operational (broken, defect, …). For instance: resistive signal is the backup for the capacitive signal in case of water, blood or broken front.


    • DOUBLE FUNCTIONS: Ability to perform “double confirmation”. Increased ease of by combining two functions in one movement. The first screen can be used to navigate until the desired position has been reached after which the second screen makes the activation possible through an intentional push. Just think of a medical application in which a surgeon navigates a laser-pointer to the correct position and pushes the screen to activate the laser. The first screen is used to make the intention clear or for aiming, the second provides confirmation.

    Previously, ClickTouch had provided a solution with redundancy for membrane keypads. In combination with the Two Touch Redundancy Technology for touchscreens, ClickTouch is the first to develop a full range of HMI’s for critical applications.
