Development of a Real-Time Eog-Based Acoustical Beamformer Algorithm for Binaural Hearing Devices

L'électro-oculographie (EOG) est une technique permettant, notamment, de mesurer les fonctions de la motricité occulaire grâce à des électrodes périorbitales enregistrant la différence de potentiel entre la cornée (potentiel positif) et la rétine (potentiel négatif). Cet article présente la preuve de concept d’un algorithme de beamforming acoustique utilisant l’angle de déplacement occulaire obtenu à partir d’enregistrements EOG pour optimiser la localisation et la perception des sons. Un tel algorithme permettrait d’optimiser l'expérience utilisateur des personnes utilisant des dispositifs auditifs binauraux tels que des audioprothèses ou des protecteurs auditifs numériques, en améliorant, par exemple, la reconnaissance de la parole en présence de bruit.
