I'll think about using multiple types of devices (watch, lenses, wearables). Contact lenses for measuring blood sugar already exist, so smart contact lenses will exist all over the place 2000 years from now. Probably also embedded technology in the body, although I doubt I'll explore it.
Swatches is really intended as a generic term, like smartwatch, except I don't want to get into copyright argument with a big company. Nevertheless, Acme will be a major manufacturer.
I don't recall a holodeck in Voyager.
Earbuds alone won't be enough. Other characters need to hear what the AI is saying. Technically, the wearer could speak what the contact lens displays in front of him/her. Avoids the complexity of people having to link up their lenses.
Why flickering holos? My holos project steady high quality images.
I think I'll include at least some references to smart contact lenses and wearables for a little realism, but will probably stick to smart watches for most intelligent interactions.
I'm now leaning toward wise thinker or wisething as the generic for smartwatches. Wise thinker would mostly be referred to as thinker. Anyone have a preference? See the original list above for others. Thinker is blandish sci-fi. Wisething is a little cuter, like splat inhibitors. Others above border on silly, which could be good, too. Wise doohickey, anyone?
Thank you, K, I appreciate the detailed feedback.
