Can Holograms Reform Mathematical Education As We Know It?
Regardless of the angle you approach it from, sometimes math is just hard. Even with a visualization tool like a SMART Board, students can still struggle with topics like geometry, where emphasis is placed on the position of figures and the properties of space. A holographic display is the key to not only visualizing difficult concepts in 3D, but also exhibiting them in an engaging medium.
A few weeks ago Nolan, one of our Unity Developers, built a tesseract in Unity and ported it into his Looking Glass as a part of our internal hackathon. A tesseract, also known as a hypercube, is a four-dimensional object that appears to us third-dimensional dwellers as a cube-like space bounded by cubes.

We won’t get too deep into the four-dimensional weeds here, largely because it’s a highly abstract concept that is much better conveyed as a hologram than as a blog post. What we will say, is that displaying a tesseract in a Looking Glass makes conceptualizing the fourth dimension much easier than drawing it out on a 2D whiteboard, given that it is explained using 3D objects.
“It’s not necessarily something that couldn’t be rendered in a 2D space, it’s just super hard. It was interesting for me to try to represent a 4D object in a 3D space, which is something that a volumetric display is uniquely good at.”
Being largely theoretical, the fourth dimension isn’t something we can easily visualize. That is, unless you’ve got a Looking Glass, in which case it’s only one dimension away.
The notion that a highly abstract concept, such as the fourth dimension, can be made accessible to students in a comprehensive and engaging way is more than powerful. It makes us reevaluate the ways in which we deliver conceptually challenging material.
