Since eyes all the same will permanently from the text on road and is reverse. Unfortunately, I do not have experience of usage VR of points, therefore I cannot present restriction, but unless the reader cannot work approximately so: - the text on a surface virtually remote approximately on meter-two - huge magnification of the text unit which is read by the user, at the same time page surrounding it to reduce and cover . - to trace position of eyes and to recognize, where exactly the user looks. As soon as focus is drifted on the last words of the unit, to process a scene. To do the same at focusing on other place of page. In this case immediately readable text in the sizes will be huge that levels "races at walking". Still it is possible to use the built in sensors for attempt to neutralize influence of steps.
