An apparatus for marketing investment services comprising a display screen aligned along a vertical axis and a horizontal axis, a position detector, and a computer device. The computer device may receive at least one signal from the position detector indicating a position of a viewer relative to the display screen in the horizontal axis and a perpendicular distance of the viewer from the display screen; cause the display screen to display a user interface. The user interface may comprise an age scale aligned with the horizontal axis, an asset scale aligned with the vertical axis and a chart of assets versus age. Upon determining that the perpendicular distance of the viewer from the display screen is less than a predetermined value, the computer device modify the interface to display an element at a first position on the age scale corresponding to a position of the viewer relative to the display screen in the horizontal axis.
