Tactile Feedback for Locked Device User Interfaces

Abstract

A computer system displays a user interface with one or more user interface elements and a background element. In response to detecting an input directed to the user interface: if the input is directed to a respective element of the one or more user interface elements and meets first input threshold criteria, the computer system performs an operation associated with the respective element; if the input is directed to the respective element and does not meet the first input threshold criteria, the computer system forgoes performing the operation associated with the respective element; if the input is directed to the background element and meets second input threshold criteria, the computer system changes an appearance of the background element; and, if the input is directed to the background element and does not meet the second input threshold criteria, the computer system forgoes changing the appearance of the background element.
