See-out, no-see-in, blind for a window, door, or room partition, or in short a noseein.

摘要

A semi-mirrored translucent surface is angled so that when looking towards it from one side (from the outside) one sees the reflection of an illuminated surface that is brighter than what is beyond (the inside) and when looking towards it from the other side (from the inside) one's view through is not blocked by the reflection of a dark surface. The effect is that looking in from the outside, one sees what appear to be illuminated closed blinds and looking out from the inside one sees through what appear to be open slats.
