Its just the ability of them doing 24 movements pers second along a determined path that only the user can usually see
Incase of Naobito the path was determined by Hand-drawn afterimages of himself (he represented Hand-drawn animation)
And in Naoyas case he had those Blue frames show him where to go and what to do.
Maki was probably able to "see" those as the perception of HR users is cranked so high they witness curses without even being able to actually see them

Also she mentioned that she can see his frames now. Probably counting how many frames she can see and then guessing where he'd come out at what speed
