[IntinyBut]

I remember seeing a documentary about a boy who had his eye removed at early eage because of rare and aggressive cancer.
However he developled amazing ability to navigate using echolocation.
The reason i am using this example because it make me think about contact, which as I remember that contact is defined as comming together
a) external object ( car house human being, e.t.c)
b) associated organ ( but in this case it is ear!!!) ,
c) associated consciousness ( will it be eye or ear counsciesness? If it eye how can there be a contact, since eyes are removed. If it is ear, that how is it possible since he sees forms using ears.)

Should the definition of contact be modified?
Also you know there is medical device which allows blind humans to get vary low res images using tounge?

How should one make sense of contact in this case.

My thoughts at the moment are that it is not the eye exactly, but object that senses forms ( sounds, smells, e.t.c). ( Which in this case it can be, ear, touch, eye, tounge ( not sure about nose) )
