Aspects of the technology utilize an integrated computing device that supports a shared, communal interaction while still enabling a personalized experience. This includes a unified desktop experience based on presence, a shared family or common space as part of an ambient visual display, and seamless switching involving user interface elements when the display device is rotatable. A presence sensor detects whether someone is at or near the device. When at least one person is identified, specific information is surfaced on a display based on the current context, enabling the person(s) to interact with the device in selected ways. The device evaluates a current presentation state of the display and selects content items to present. The presentation state can include content currently being displayed, other context signals, or any other information associated with the state of the device, such as whether the device is locked or logged-in, for example.
