1. A gaze direction determination apparatus, comprising:
first capturing means disposed at a first specific known location, for capturing a head of a driver within a vehicle;
at least second capturing means disposed at a second specific known location, for capturing at least a head of at least a second person;
third capturing means for being installed near said driver and being directed horizontally, for capturing a body of said at least said second person; and
a controller
for processing captures of said first capturing means, for determining from said captures' processing that eyes of said driver are horizontally directed towards at least a second person, and
for determining human communication in case determining from said captures' processing that said eyes of said driver and eyes of said at least second person are horizontally directed one towards the other; and
reporting means,
wherein said first capturing means is installed above said driver and is directed vertically downwards, for capturing a nose thereof from above said nose,
thereby determining a horizontal angle of said nose, for applying said determining that the eyes of said driver are horizontally directed to the eyes of said at least second person, and
wherein in case of said determination that
the eyes of said driver and the eyes of said at least second person are horizontally directed one towards the other,
and that a brake circuit of the vehicle inputs that the driver has braked a brake pedal of the vehicle,
then said controller is configured to control said reporting means to announce advancing allowance to said at least a second person,
wherein said horizontal angle of said nose, and a horizontal direction of at least the second person as captured by the third capturing means, must be equal for applying said determining that the eyes of said driver are horizontally directed to the eyes of said at least second person.
