Abstract
An embodiment provides a feedback method, applied to an electronic device provided with a touchscreen. The touchscreen is provided with a plurality of vibration feedback elements. The method includes detecting a first contact operation acting on the touchscreen, and obtaining first location information of a first contact point corresponding to the first contact operation, where the first location information corresponds to a first virtual key on a virtual keyboard. The method also includes if the first virtual key is an anchor point key, obtaining, from the plurality of vibration feedback elements, a first vibration feedback element that matches the first virtual key, and indicating the first vibration feedback element to emit a vibration wave, to prompt that the first virtual key is an anchor point key, so that the user can sense a location of the anchor point key. This can reduce difficulty in implementing touch typing on the touchscreen.
