Title
(EN) ALGORITHM ENHANCEMENTS FOR HAPTIC-BASED PHASED-ARRAY SYSTEMS
(FR) AMÉLIORATIONS D'ALGORITHME POUR DES SYSTÈMES RÉSEAU À ÉLÉMENTS EN PHASE À INTERACTION HAPTIQUE
Abstract
(EN)
Improved algorithm techniques may be used for superior operation of haptic- based systems. An eigensystem may be used to determine for a given spatial distribution of control points with specified output the set of wave phases that are the most efficiently realizable. Reconstructing a modulated pressure field may use emitters firing at different frequencies. An acousiic phased-array device uses a comprehensive reflexive simulation technique. There may be an exchange of information between the users and the transducer control processors having the ability to use that information for optimal haptic generation shadows and the like. Applying mid -air haptic sensations to objects of arbitrary 3D geometry requires that sensation of the object on the user's hand is as close as possible to a realistic depiction of that object. Ultrasonic haptics with multiple and/or large aperture arrays have high-frequency update rates required by the spatio-temporal modulation. More efficient haptic systems require the prevention of a channel of audio unintentionally encoding phase information that may distort its perception.

Des techniques d'algorithme améliorées peuvent être utilisées pour un meilleur fonctionnement de systèmes à interaction haptique. Un système propre peut être utilisé pour déterminer, pour une distribution spatiale donnée de points de commande avec une sortie spécifiée, l'ensemble de phases d'onde qui sont les plus efficacement réalisables. La reconstruction d'un champ de pression modulé peut utiliser des émetteurs émettant à des fréquences différentes. Un dispositif réseau à éléments en phase acoustique utilise une technique de simulation réflexive complète. Il peut y avoir un échange d'informations entre les utilisateurs et les processeurs de commande de transducteur ayant la capacité d'utiliser ces informations pour des ombres de génération haptique optimales et analogues. L'application de sensations haptiques en l'air pour des objets ayant une géométrie 3D arbitraire nécessite que la sensation de l'objet sur la main de l'utilisateur soit la plus proche possible d'une représentation réaliste de cet objet. Des haptiques ultrasonores ayant des réseaux d'ouverture multiple et/ou de grande dimension ont des vitesses de mise à jour à haute fréquence requises par la modulation spatio-temporelle. Des systèmes haptiques plus efficaces nécessitent d'empêcher un canal d'audio de coder accidentellement des informations de phase qui peuvent déformer la perception.
