Why does someone with eyes tied follow a circular path if left to walk in a huge yard(kilometers), that occurs even if he thinks that he is walking in a straight line?

In my opinion once you drawn a well enough curve your balance shift towards inner side of circle and you fullfill to spiralate inwards. But what shifts the balance inward?

It has nothing to do with perception.

It's simply because there are infinitely many ways to go in circles, while only one way to go straight. Even a slightest bias towards one side will produce a circle. When other cues are given to correct the bias, one is able to track straight lines.

Even robots (or toy cars) that are designed to go straight lines will go in circles without sensory feedback!

Not even zigzag or rough path, its an arc or circle. Sorry delete your answer. –  Waqar Ahmad Sep 25 '13 at 21:20
    
@WaqarAhmad I do not see anything wrong with my answer. I have updated it to include a robot example. –  Memming Sep 25 '13 at 21:23
    
Now thats good. Humans are much chaotic and complex in their brains, they are supposed to follow irregular paths. What about birds flying? –  Waqar Ahmad Sep 25 '13 at 21:30
    
One thing more even when they are lost in jungle or market they follow the circular trend, but that seem kind of fear for not go too far away from the safe niche. –  Waqar Ahmad Sep 25 '13 at 21:43
