Any thoughts about the contacts vs. swatches?
Why not both? I have contacts, wrist devices, glasses, hair dongles, tiaras, shoes, ocular implants, and I'm sure I'll have five or six more by the end of this draft. Or are you saying that there's going to be a massive technological convergence in the future?
I'm leaning toward swatches, since they're an all-in-one device (video in/out and audio in/out). I could potentially add 3D video to the swatches. I used to have that, but thought it was silly because simple arm movements would throw off the image, but maybe that's not such a big deal, or I could claim software adjusts to hold the picture steady. Requires explaining.
How's about "watch". Of the category of watch could be watches by different companies such as the Swatch, the Galaxiwatch and the Pepsi-watch. It sounds like you're trying to name all the devices under one trademark, which would be uncommon for a free trade society (you wouldn't want a communications monopoly - that could get ugly).
Currently, I use 3D for a holo movie, dining table centerpieces, and the display table in the War Room. In each case, there is an underlying projector, so contacts struck me as unnecessary so far.
Ok, then you should nix the contacts. A simpler backdrop allows you a more complex foreground of the descent into possible madness. Take a page out of Janet's book: sometimes a windmill really is just a random here-to-fore unimportant windmill. This puts the spotlight on the characters rather than the tech
Speaking of nixing tech, did Voyager ever have any holodecks?
That said, the only real limitation to contact lenses is audio out because of the vibrations against the eyeball. Any ideas on how best to address that? I could have the contacts transmit audio out digitally to a wireless speaker mounted on the head. Meh.
Hmm this is a legitimate problem. Even numbing the eye, the vibration would still cause vision fluctuation. I also bet you'd get a lot of retinal detachment cases because that pesky thing can come loose for much less provocation.
option a) audio comes from the nearest loudspeaker == audio party line
(Note: This is what I currently use. When Laurie is in the taxi, she has full audio (via the taxi's speakers). The moment she leaves the taxi, she's down to video with subtitles and/or texting. She could speak after that, but everyone around would hear her side of the conversation.)
option b) contacts paired with ear buds
option c) go old school and have flickering Star Wars style holograms. Have people connect via protocol droids instead of hald-held technology (btw why oh why do Star Wars droids need to speak to each other? Don't they come equipeed with Wifi?)
