Self-motion Perception from Optic Flow and Rotation Signals
Year: 2000
Type: dissertation
Abstract: The value of optic flow for retrieving movement direction was recognised already two\\ncenturies ago by astronomers, searching the sky for meteorite showers. The point from\\nwhich the shower appeared to emanate they termed the radiant, knowing it indicated\\nthe direction along which the meteorites were heading towards the observer. As Gibson\\n(1966) pointed out, humans may use the shower of light that hits the eye ball when\\nthe eye moves relative to the stable world, to retrieve their direction of movement\\nrelative to the world (heading). Motion pictures nowadays offer opportunities to a\\nlarger audience to appreciate the value of optic flow in isolation. The ongoing display\\nof a diverging cluster of stars, trademark of a well-known movie maker and popular\\namong the screensavers, can bring about a strong sensation of moving forward while\\nin fact one remains seated.
