Abstract[English]
A lightweight, cost-effective electrooculography (EOG)-based signal analysis device designed for non-diagnostic, commercial communication and control of external devices. The device includes ocular electrodes (102a, 102b, 102c) for capturing vertical eye movement signals and an auricular reference electrode (300) to improve signal stability and comfort. These signals are processed by a microcontroller (202) and transmitted to an external signal interpreter (202), facilitating interaction with devices such as computers, robotic systems, and prosthetics. The invention addresses the challenge of providing accessible, portable communication solutions for individuals with neuro-motor impairments, ensuring practical use with minimal setup requirements. The primary applications include communication support for conditions like ALS, Locked-in syndrome, and cerebral palsy, enabling users to control external systems efficiently.[French]
La présente invention concerne un dispositif d'analyse de signal basé sur l'électrooculographie (EOG), léger et économique, conçu à des fins autres que diagnostiques, notamment pour la communication commerciale et la commande de dispositifs externes. Le dispositif comprend des électrodes oculaires (102a, 102b, 102c) destinées à capter les signaux de mouvement oculaire vertical et une électrode de référence auriculaire (300) visant à améliorer la stabilité du signal et le confort. Ces signaux sont traités par un microcontrôleur (202) puis transmis à un interpréteur de signaux externe (202), ce qui facilite l'interaction avec des dispositifs tels que des ordinateurs, des systèmes robotiques et des prothèses. L'invention vise à fournir des solutions de communication accessibles et portables aux personnes souffrant de troubles neuromoteurs, en garantissant une utilisation pratique avec des exigences de configuration minimales. Ses principales applications comprennent l'aide à la communication pour des pathologies telles que la SLA, le syndrome d'enfermement et la paralysie cérébrale, permettant ainsi aux utilisateurs de commander efficacement des systèmes externes.
