Devices and methods for processing and disambiguating touch inputs using intensity thresholds based on prior input intensity

Abstract:

An electronic device detects an input sequence that includes an increase in intensity of an input that corresponds to a first input event. If the input sequence includes a second input event, including a decrease in intensity of the input after the first input event, a long press is not detected and a first operation is performed. If the second input event is not detected within a second time period that is longer than the first time period and the input had a characteristic intensity above a respective intensity threshold between when the first input event was detected and when the second time period elapsed, a long press is detected on an accelerated basis, and a second operation is performed. Finally, a long press is detected if the second input event is not detected within a longer, default time period, and the second operation is performed.
