Abstract
(EN)
Example systems may include a head-mounted device configured to present an artificial reality view to a user, a control device including a plurality of electromyography (EMG) sensors, and at least one physical processor programmed to receive EMG data based on signals detected by the EMG sensors, detect EMG signals corresponding to user gestures within the EMG data, classify the EMG signals to identify gesture types, and provide control signals based on the gesture types, wherein the control signal triggers the head-mounted device to modify the artificial reality view.. Various other methods, systems, and computer-readable media are also disclosed.

L'invention concerne des exemples de systèmes pouvant comprendre un visiocasque conçu pour présenter une vue de réalité artificielle à un utilisateur, un dispositif de commande comprenant une pluralité de capteurs d'électromyogrammes (EMG), et au moins un processeur physique programmé permettant de recevoir des données EMG en fonction de signaux détectés par les capteurs EMG, détecter des signaux EMG correspondant à des gestes d'utilisateur dans les données EMG, classifier les signaux EMG afin d'identifier des types de geste, et fournir des signaux de commande en fonction des types de geste, le signal de commande déclenchant la modification par le visiocasque de la vue de réalité artificielle. La présente invention concerne également divers autres procédés, systèmes et supports lisibles par ordinateur.
