Talk:Data Headpiece

At what tech level does this become a contact-lens? Ditto for an iris-implant? An implanted eyes have this functionality? BackworldTraveller (talk) 07:19, 6 June 2020 (EDT)

This becomes an interesting fight between old TL advancement scales and newer ones. The Cybernetic eyes eyeball display is TL-11, for basically mounting this on your eyeball. The "Slick" version, which would correspond to an iris implant is TL-13. If we want to keep the consistent tech advancement, this should be TL 9 or TL 10. But this also includes a video/audio recorder, which pushes the eye mount version to TL 12, TL14 for the iris implant version. For the contact lens version, I'd put it around TL-13 as well.

I also, on re-reading this, it is a holographic display. And all holographic displays are TL-13. Tjoneslo (talk) 13:17, 6 June 2020 (EDT)

This is where the definition of "Holographic" is interesting...Is the projection of two 2-d images onto the retina holographic? A holographic image is (I'd think) a 3-d image visible to any viewer and thus apparent in real-space. This can be simulated for one viewer only by stereoscopic projection. So have the definitions got confused. A holographic headpiece, if truly projecting holograms, is a weird concept!

i.e. A standard holographic projector makes an image through which you can move, and which is visible, unaided, by all present. What is described is much more closely related to a Virtual Reality headset that are starting to come onto the market now. Does the Data Headpiece need to exist twice with the two separate technologies? Can a data headpiece make sense in the latter form?

You're right there are two versions of this. One is the Heads up display version with 2D video display, and hooked to a computer you get a virtual world overlay. This is, with the weirdly extended computer technology curve of Traveller, TL-9 or TL-10.

There are two parts to the holographic technology of Traveller. One is the fully 3D display. Which can be seen by everyone but can be designed for only one person as the viewer. But the other part is the interactivity. So you can project an image, say a box, but the technology lets you reach out and touch it, turn it around, open it and the like. No magic gloves. Again, weirdly extended technology curve pushes this to TL-12 or TL-13.

But this is me trying to madly handwave a future technology written about more than 30 years ago. In the real world you can already do all of these elements: High resolution display on an eyeglasses sized object, using IR or infrasound trackers for hand or body movements and voice commands. So internal consistency vs mapping to the real world. Tjoneslo (talk) 09:54, 7 June 2020 (EDT)
