Abstract:

An electronic device: detects an input on a respective button. Tactile outputs are generated to indicate that the respective button has been activated in place of a mechanical switch that detects activation of the respective button when the respective button is mechanically compressed. In response to detecting the input on the respective button: in accordance with a determination that the input meets activation criteria, the electronic device provides a first tactile output with a first tactile output pattern that includes: between 0.5 and 4 cycles of an oscillation of one or more tactile output generators relative to corresponding neutral positions of the one or more tactile output generators. The oscillation of the one or more tactile output generators occurs at a frequency between 80 Hz and 400 Hz. In accordance with a determination that the input does not meet the activation criteria, the electronic device forgoes providing the first tactile output.
