The cybernetic interface jack was used by native Aruzans, along with an Attanni, to share feelings and emotions. Gold-plated and located below the ear, the interface jack allowed for a direct connection to the emotion centers of the brain.

About 3 ABY, Dengar, a Human cyborg, and Manaroo, an Aruzan tech-empath, shared their love for each other using their cybernetic interface jacks and an Attanni. Marriage occurred a short time later.
