Abstract: A method performed by a head mounted display (HMD) device includes: determining a sleep onset preparation start time; and displaying, on a display, a sleep onset preparation screen to which a visual effect is applied, from the sleep onset preparation start time, in a stepwise manner during a sleep onset preparation time interval, where the visual effect that is applied in the stepwise manner comprises a visual effect of switching a virtual screen output through an entire display area of the display to a video see through (VST) screen, where the VST screen displays the virtual screen with a non-virtual screen as a background in the entire display area of the display, where the non-virtual screen is based on an image captured through a front camera, and where the virtual screen is based on content executed by the HMD device.
