What could be going on with my son?

My son is 8 years old and he can’t really look at where I’m pointing. I can point to something and he won’t have a clue where I’m pointing. It’s really odd and I never thought twice about it cause it doesn’t seem like a big deal to me but I’m just curious if there is a term for this or something? He doesn’t have any vision problems but he has hypersensitivity in regards to his senses (specifically hearing, taste and touch). I’m just wondering if anyone has any experience with this or if they know more about it.
