Volumetric display from Voxon

Volumetric display from Voxon

Voxon has been showing off it’s Voxon VX2 VLED technology to create interactive volumetric holograms. It costs $6,800 so it’s definitely not cheap.

It’s likely using a high rpm spinning panel to generate the image which means that dampening the sound of the spinning array, keeping the display carefully synced to avoid pixel drift, and are some of the primary engineering concerns. They do provide a Unity and Blender SDK which is interesting.

Here’s a version of Doom playing on the volumetric display

Reminds me of the fellow that re-created the projector from Riven using a similar method.

Looking Glass is now making the Looking Glass Go – a much thinner and mobile version of their glasses free holographic Looking Glass Portrait display. This isn’t new tech, but it is interesting to see people working in the space again.

With their software, you can make your own images and display animated content as well. Viewing angle is about 60 degrees and is created from up to 100 different still images.

It’s not limited to static images. You can even use the Looking Glass API to run this Unity version of Doom on the display and can look around pillars and objects.

CETI (Creative and Emergent Technology Institute) is a local creative group that experiments with different technologies for creating unique experiences. Sarah Turner is a local artist that has been experimenting with different media and video technologies – which she calls the Mobile Projection Unit. This project has set up projection mapping displays at a number of different art and media festivals.

In this video she goes over some of the things she’s learned from these projection mapping setups:
