A device with a movement-based user interface (UI) may establish thresholds that govern when the UI moves and when the UI stays still to avoid interruptions to the user experience based on undesired movement, such as movement caused by a vehicle, etc. The thresholds may be based on detecting a movement type experienced by a device (e.g., bicycle, car, etc.). When movement is detected beyond the threshold the UI may be configured to smooth a displayed UI transition from a first position to a second position to improve the user experience.
