Is it possible to create an interactive hologram or 3D object without the use of a VR headset?

Yes, absolutely.

Honestly, you’ll see more of that with AR glasses than you will with VR headsets.

But assuming you mean not utilizing any wearable technology, the answer is still yes. You can see it with Pokemon Go’s AR mode. Essentially it utilizes the camera in your phone to track the environment and create an AR object (in this case a pokemon) that you can interact with.

Edit: The above answer is specifically for an interactive 3D object. Theoretically the same technology (not the display method, but the CG generation/interactivity method) can be used for an interactive hologram, but I haven’t seen video holograms done well enough to truly be considered viable. That doesn’t mean they’re not out there, I’m just not aware of them.
