All the members of Rava's family use VR-glasses. They are used to communicate both with Cordelia (AI) and with other family members.
In the first scene, Rava realises that Cordelia will not be able to either communicate or mediate communication that happens via her family member's VR-glasses for as long as her transmitter socket remains damaged. Furthermore, she will not be able to record and upload any more of Rava's family history, memories, etc.
In the second scene, Rava is calling Uncle Georgo using the VR-glasses to ask what kind of cable Cordelia uses. She needs the cable to plug Cordelia into the ship's system, to make it possible for her to remember where the spare socket may be.
