The present application discloses a privacy user interactive apparatus including a display panel configured to display a stereoscopic image of a user input interface in a three-dimensional display space; a three-dimensional positional sensor configured to detect a three-dimensional position of a user input object; and a processor coupled to the display panel and the three-dimensional positional sensor, configured to control the display panel to display the stereoscopic image of the user input interface in the three-dimensional display space, configured to receive an input control signal from the three-dimensional positional sensor, and configured to execute an operation in response to the input control signal. The display panel is configured to display a three-dimensional image of the user input interface in the three-dimensional display space and a two-dimensional image outside the three-dimensional display space.
