Abstract
A method, apparatus and computer program product are provided for displaying messages by reducing a reflectivity of a display. A display, such as a smart mirror, provides reflective properties and digital information. The reflectivity of some portions of the display may be altered such that the display provides the visual effect of steam. By varying the reflectivity in different portions of the display, messages may be provided via the display so as to appear written in the steam. Trigger actions, such as a user entering the vicinity, the detected sound of miming water, and/or the like, may cause the visual effect of steam or display of the message. A user may provide a message by a hand gesture, or writing the message in the air and see the message at is provided via a display. Users may transmit messages to other users, and may view received messages in the display.
