Enabling noise-tolerant capacitive-touch HMIs with MSP CapTIvate technology
Capacitive touch as a human-machine interface (HMI) technology is finding its way into more and more applications each year. It is rapidly becoming a popular technology for mechanical button replacement in end equipment such as small and large home appliances, industrial control panels and automotive center stacks. While the technology offers designers new freedoms in how they can differentiate their products via the user interface, it also presents new challenges. The challenges arise from the fact that these markets often share two important characteristics: they are high in electrical noise and they have safety-critical functions controlled by the user interface.
