New to AR. Decent augmented reality helmet? Capabilities?

Hello to the forum. I am an older E.E. getting into the Augmented reality area and I am not sure if what I am looking to do in AR is yet a reality. What I am looking to do is to simply generate graphics as an overlay to reality by transmitting, either through wifi or cable, to a AR helmet. It is important to be able to see through the helmet visor. I’ve been doing tutorials on opencv, CUDA, graphics, Python and various machine learning topics but I am not sure of where to go to purchase a helmet, at least for experimentation. Is there a central place where such hardware is discussed?

Thank You

could you find any solution to your problem
I’m doing research on this
