Headsight was the first step in the evolution of the VR head mounted display but it lacked the integration of computer and image generation.Ivan Sutherland described the “Ultimate Display” concept that could simulate reality to the point where one could not tell the difference from actual reality.
In 1929 Edward Link created the “Link trainer” (patented 1931) probably the first example of a commercial flight simulator, which was entirely electromechanical.
It was controlled by motors that linked to the rudder and steering column to modify the pitch and roll.
His concept included: “The ultimate display would, of course, be a room within which the computer can control the existence of matter.
A chair displayed in such a room would be good enough to sit in.
In hindsight the experience Weinbaum describes for those wearing the goggles are uncannily like the modern and emerging experience of virtual reality, making him a true visionary of the field.
