Too late for an edit but I was going by what was shown in the video, which very much didn't look it could do that.
That said, that's still basically "3D but without glasses", not exactly the Holodeck "hard light" future tech many people think of when they hear "real hologram".
- SamBam 7y agoYes. Most people think of something like this image of princess Leia coming out from R2: https://edge.alluremedia.com.au/m/g/2017/01/star-wars-hologram.jpg https://edge.alluremedia.com.au/m/g/2017/01/star-wars-hologr... That requires 1. The imagine coming "out" of the screen such that you can even see the image at 90º to the projector 2. The image occluding the physical background. As far as I understand, such a thing is impossible as seen in the still above (i.e. from a single projector), but can be fakes by using stuff in the air to scatter the light, like this research project (1) or this not-great version that uses fog (2) (1) https://www.sciencemag.org/news/2018/01/princess-leia-holograms-one-step-closer-reality https://www.sciencemag.org/news/2018/01/princess-leia-hologr...

- vilhelm_s 7y agoI mean, a real hologram (made using light interference) is also not Holodeck hard light.
- te0006 7y agoYes, but at least a real hologram creates an actual depth sensation as the eye's focus needs to adapt. This means 3d impression works even for people with reduced stereoscopic eyesight, and does not create headaches due to a mismatch of scene depth vs. physical display depth. Such holographic displays do exist, e.g. www.seereal.com (which BTW recently received an investment by Volkswagen).
