Abstract: This disclosure describes, in part, techniques for using presence detection in order to switch between power modes of a display device. For instance, the display device may operate in a first power mode by deactivating a display. While operating in the first power mode, the display device may use a sensor to detect a presence of a possible object. The display device may then switch to a second power mode in order to verify that the possible object is an actual object. In response, the display device may switch to a third power mode by at least activating the display and presenting a user interface using the display. The display device may then receive an interaction. In response, the display device may switch to a fourth power mode by at least presenting content.
