Title
(EN) tactile feedback method
(ZH) 触觉反馈方法
Abstract
(EN)
The invention provides a tactile feedback method. The method comprises the following steps: S1, carrying out algorithm training on an audio clip containing a known audio event type to obtain an algorithm model; and S2, obtaining audio, identifying the audio through an algorithm model to obtain different audio event types in the audio, and matching the audio event types with different vibration effects according to a preset rule to serve as tactile feedback to be output. Compared with the prior art, the tactile feedback method disclosed by the invention is applied to the mobile electronic product to provide real-time tactile feedback for a user, so that the use experience of the mobile electronic product is good.
