Methods, systems, and computer program products are provided for presenting a user interface on a display of a computer system. A presence of a second person in a proximity of a computer system other than a first person using the computer system is determined. A user interface is automatically selected based on the determined presence of the second person. In an absence of the second person, a voice interface is selected. When the second person is present, a text entry interface is selected. The selected user interface is presented to the first person on a display of the computer system.
