Abstract:
An electronic device, while tactile output generators are in a low-power state, receives an indication that a user interaction has started. The device, if the indication meets tactile output generator preparation criteria, sets the tactile output generators to a low-latency state at a first time. Thereafter, the device, if the user interaction has reached a respective portion of the user interaction that is associated with a tactile output before a predefined amount of time since the first time has elapsed and the tactile output generators are still in the low-latency state, generates the tactile output using the tactile output generators with a reduced latency. If a tactile output has not been generated for at least the predefined amount of time since the first time, the device transitions the tactile output generators from the low-latency state to the low-power state.
