Motion Extrapolation Into the Blind Spot

Motion extrapolation into the blind spot.

The flash-lag effect, in which a moving object is perceived ahead of a colocalized flash, has led to keen empirical and theoretical debates. To test the proposal that a predictive mechanism overcomes neural delays in vision by shifting objects spatially, we asked observers to judge the final position of a bar moving into the retinal blind spot. The bar was perceived to disappear in positions we...

Bio-Inspired Motion Detection for a Blind Spot Overtaking Monitor

The rear-view mirror is unhelpful when an overtaking car is in the blind quadrants (blind spot). In this contribution we describe the software implementation of an algorithm to monitor vehicle overtaking processes. This algorithm detects the vehicle to the rear, and discriminates whether it is approaching or not, and if approaching, it alerts us of its presence. The proposed system is based on ...

Blind Spot

In monocular viewing there is a region in the peripheral visual field that is blind due to the absence of photoreceptors at the site where the optic nerve exits the eye. This region, like certain other blind spots, nonetheless appears filled in (Walls 1954). Ramachandran (1992a,b) has recently reported several novel demonstrations of filling-in at the blind spot. In this essay we critically ree...
