In this blog post you can view two videos that go into detail about the functionality of the human-machine interface (HMI) product sample and an overview of how capacitive touch membrane switches work. The transcription of both videos is also provided below. Take note that the transcriptions have been edited for better readability.

As capacitive touch human machine interface (HMI) assemblies become more popular, both designers and users are becoming more familiar with the technology as it replaces traditional mechanical HMI products. These capacitive touch HMIs can be used in extreme environments, with users wearing gloves, and can operate reliably for years.

Just as a mechanical HMI (membrane switches, tactile switches, etc.) relies on the overlay material properties to determine system function, capacitive touch HMIs rely on the overlay material properties to drive capacitive touch sensitivity and overall system performance.

When our customers are in the preliminary stages of launching a new SMART HMI project, they typically reach out seeking advice on the best way to start. With what can amount to a near infinite number of HMI design options and system feature combinations, brainstorming an embedded firmware project can quickly become overwhelming. Where does one begin? How does the firmware work? What level of detail is required now?

Recently I spent the weekend at a family member’s home and experienced two failures of everyday human-machine interfaces (HMI) devices that truly perplexed me. One was a collapsed dome switch on a spa controller; the other was a graphical display error on a touchscreen coffee maker.
