This is not a hologram but a 3D representation of the person who are meeting with, online: The spectacular rise of holographic communication – Ericsson
Ericsson is working towards delivering 3D communications – think Zoom-like calls – using smart phones.
An interesting technology that will evolve and improve over time.
The media (and other promoters) have adopted the term “hologram” to refer to any system that creates a 3D-like experience, even when not a true hologram. Holograms use light wave interference patterns to produce a 3D image that you “look in to”.
