Title
(EN) HAPTIC FEEDBACK METHOD
(FR) PROCÉDÉ DE RÉTROACTION HAPTIQUE

Abstract
(EN)
A haptic feedback method. The method comprises the following steps: S1, performing algorithm training on an audio clip comprising a known audio event type, and obtaining an algorithm model (S1); and S2, acquiring an audio, and performing identification of the audio by means of the algorithm model so as to acquire different audio event types in the audio, finding, according to a preset rule, different vibration effects matching the audio event types and outputting same as tactile feedbacks (S2). Compared with the related art, the haptic feedback method, when being applied to a mobile electronic product, provides a user with real-time haptic feedback, allowing good usage experience of the mobile electronic product.

L'invention concerne un procédé de rétroaction haptique. Le procédé comporte les étapes suivantes : S1, effectuer un entraînement d'algorithme sur un clip audio comprenant un type d'évènement audio connu, et obtenir un modèle d'algorithme (S1) ; et S2, acquérir de l'audio, et effectuer une identification de l'audio au moyen du modèle d'algorithme de façon à acquérir différents types d'évènement audio dans l'audio, trouver, selon une règle prédéfinie, différents effets de vibration correspondant aux types d'évènement audio et produire ceux-ci en tant que rétroactions tactiles (S2). Par rapport à l'état de la technique, le procédé de rétroaction haptique, lorsqu'il est appliqué à un produit électronique mobile, fournit à un utilisateur une rétroaction haptique en temps réel, ce qui permet une bonne expérience d'utilisation du produit électronique mobile.
