Are there any guidelines, recommondations or research about using touch screens with winter gloves? I'm aware of the normal recommended defaults (44pt according to Apple's HIG, 48pt in Material Design), but those are minima.
Winter gloves come in different sizes and thicknesses, so I guess bigger touch areas are better, but I'm not sure of the thickness actually linearly correlates with precision. After all, it's not about the area covered by the glove on press, but about the pixel position that's converted to by the touch screen driver. Theoretically, a trained user with gloves could be as precise as one without any.
