yautja vision--well sensors pick up various forms of information from the surrounding environment, either heat, infared signitures, ultra violet rays, bioelectric current, and possibly other data. the information is then broadcast from the mask to the yautja using tiny screens where the 'eyes' of the mask are located.
the cloak system can be sistem of miniature cameras that pick up the light, and trnasmitted to 'screens' on the other side. these screens are not the typical t.v. screens, but much smaller and thinner, enuff to be worn as a complete system running in small electrical impulses. similar to the way an octopus uses its specialized skin to camoflage itself. becuase it uses small electrical impulses, water makes it malfunction, maybe thats why they dont function in water. my two cents
