Go watch the type me by video thread. there are awesome examples of eyemovements there-check out silly sapinne for Ne upwards and Fi lack of eye contact-although at the start she did have a few seconds of very direct Te eye contact.
Also Uumlau-Te direct alternated with Ni internal gazes. didnt notice much Fi in the video.
There was an INFJ as well-INFJs have soft eyes, as off as that sounds, but very direct. I dunno.
Anyways I am totally just throwing this out there in Ne fashion, so take it as some initial observations that could be right or wrong.
