Displays continue to get brighter and sharper, but most of them have a significant limitation. They can only display images in two dimensions. Even “3D” displays only provide an illusion of depth. You can’t, for example, see what objects look like from the side or rear.
Holapex is a small, pyramid-like device designed to sit on top of a smartphone or tablet and display holograms. It comes in two sizes optimized for a smartphone or tablet and of course uses a companion app to display them. Things seem pretty early for the project as creator Isaias J. Perez is still working out what the source of the holograms will be. However, the device is only $25 and is due to be delivered in November. Perez seeks only $600 by October 28th.
The Holapex is an inexpensive and possibly useful amusement but of course it’s a far cry from the degree of interaction one can experience with something as sophisticated as Microsoft’s Hololens. Still, it can provide exposure to holograms for a very broad audience in the way Google Cardboard provides affordable exposure to virtual reality.
