Stereoscopic goggles that you wear are well over 30 years old already. They've been done to death.
There are other technologies that don't require an glasses or headgear, and have been for some time. Making these more affordable would be a more worthwhile endeavor, IMO.
How you imagine to have a 100 degrees field of view with 1:1 in-world scaling without wearing goggles, unless you have a spheric room in you house to project a complete in-game picture on the wall? Streaming data straight to brain?
No matter what possibilities are there, you have to filter things through "reality" first to see what can truly be done and in our commercial world what can be affordable. VR goggles may have been there for a long time, but the reason their popularity never widened is because these were never done right. Watch Carmack's keynotes on YouTube on this.
