Starting at 2:46 in Clones Wars season 2 episode 7 we see both ends of a hologram communication.
I've always wondered how people somehow manage to maintain eye contact while using holograms to communicate since often, as in this case, each are viewing images of the other that greatly vary in size. Obi-wan Kenobi and Ki-Adi-Mundi are in a large room looking down on a 2-3 foot image of Luminara Unduli. Master Unduli however is holding a mobile jedi holoprojector looking down at 1 foot images of Kenobi and Mundi. How can they both be looking down at projections less than half the height of an average humanoid while still maintaining eye contact with the person on the other end?
Stranger still, at 3:16 when Anakin Skywalker enters the room, joining the other two Jedi, we see the 2-3 foot image of Unduli in the center of the room turn her entire body about 90 degrees to face Skywalker. Then Mundi speaks up at 3:25, prompting the small Unduli image to do a 180 degree turn to face Mundi. However we then immediately see at 3:29 that she never needed to turn since they've only been two little images in her hand all along. It makes no sense for Unduli to turn right and left to face people she's essentially holding in her hand. Curiously, Skywalker's image is absent from Unduli's mobile holoprojector even though we saw her turn to face him. Did he race out of the room the nanosecond he finished talking?
Just imagine they're using some type of video chat to communicate and you start to realize that things aren't adding up. Can someone explain to me how communications via hologram are supposed to work?
I'm probably placing this under way too much scrutiny but I'm a Star Wars fan who's stuck at home sick and very bored.
