As you might guess, Modal VR isn't designing something you would buy for personal use. You'd most likely use it in arcades -- think of it as a very, very advanced version of the Virtuality rigs from the 1990s. Businesses could also create custom VR apps for their workers, such as 3D modelling tools that let engineers see life-size examples of their work.

Modal's technology is still in the prototype stage, and it will only start shipping beta developer kits "soon." If it works as well as promised, though, it could extend not just the capabilities of VR, but its reach. While many people can't justify buying their own hardware, they might not have to. You'd only have to pay on a per-session basis, and could join in multiplayer games that are impractical (or in some cases, impossible) with existing tech.
