Touch sensitive light controls are very cool - you simply run your finger across a panel and behold the glow. It’s a great way to increase reliability: it eliminates the need for moving parts and the resulting gaps where dirt, water, or air can penetrate and corrode the fixture. But try to turn the light on in the winter when you’re wearing gloves: darkness.

US Air’s short-hop propeller planes have such touch sensitive switches. When it’s 70 degrees outside (or 90 inside, as there’s no A/C) the switches are fine, but in the winter the cabin is dark: nobody can operate the switches with gloves on.
When designing anything, ask: Where has the user just been? What are they wearing? Does this change by season?
The same problem would prevent gloved laborers from operating a touchpad on a laptop. Other glove wearers: medical professionals, food service personel, artisans, athletes, and toll collectors.
