Abstract

The horizontal component of the human electro-oculogram was recorded using dry electrodes. The voltages obtained (e) for gaze angles (θ) up to ±60° were analysed to test the relationships e=Eθ and e=Em sin θ. It was found that up to about ±45° the linear and sinusoidal relationships accurately represented the data. For gaze angles greater than ±45°, the sinusoidal relationshlp provided a slightly better fit for the data.

Zusammenfassung

Die horizontale Komponente des menschlichen Elektrooculogramms wurde unter Benutzung von Trockenelektroden aufgezeichnet. Die gemessenen Spannungen (e) für die Blickwinkel (θ) bis zu ±60° wurden anlysiert, um die Beziehungene+Eθ unde=E m sin θ zu prüfen. Es wurde gefunden, dass bis zu etwa ±45° die lineare und die Sinusbeziehung die Messdaten genau beschreiben. Für Blickwinkel über ±45° ergab die Sinusbeziehung eine geringfügig bessere Beschreibung der Messdaten.

Sommaire

On a enregistré la composante horizontale de l'électro-oculogramme humain à l'aide d'électrodes sèches. Les tensions obtenus (e) pour les angles de vision (θ) jusqu'à ±60°, furent analysés afin de vérifier la relatione=Eθ ete=E m sin θ. On trouva que jusqu'à ±45°, les relations sinusoïdale et linéaire représentent les données avec précision. Pour les angles de vision supérieurs à ±45°, la relation sinusoïdale est en accord légèrement meilleur avec les données.
