CIE x048-OP25

In order to examine the effect of the translucent level of each layer on the visual privacy and the view when the window equipment is divided into three sections, the subject experiment was carried out. It was found that visibility from inside and estimated visibility from outside were proportional to each other regardless of the window equipment condition. The relationship between visibility from inside and estimated visibility from outside was affected by the shielding position of the window equipment, and it was revealed that the clearer the view from the middle layer, the more privacy could be secured. In addition, it was suggested that opening the lower level of the window rather than the upper level would ensure both privacy and view.
