Human$-$Machine Interface $($HMI$)$ in Safety$-$Critical Systems: o In a safety$-$critical environment $($e$.$g$.,$ medical devices or industrial control systems$),$ reliable HMI is crucial. Using concepts from the lecture, discuss the additional considerations required for HMI design in safety$-$critical systems compared to consumer systems. What interface characteristics would ensure reliability, and how might you address potential risks in the design process?
