So if you wiggle a coffee cup in front of the camera, you're feeling that in your back, and amazingly, blind people got pretty good at being able to determine what was in front of the camera just by feeling it in the small of their back.
Nii et kui kaamera ees oli kohvitass, tundis uurimisalune kohvitassi kuju oma seljal. Imelisel kombel kohanesid uurimisalused kiiresti ning suutsid juba varsti tuvastada kaamera ees olevaid objekte ainult tänu sellele, et nad tundsid neid oma alaseljal.
