Obama Speaking

Has anyone noticed that while addressing a gathering President Obama rarely looks at the audience sitting (or standing) in the middle of the venue. He sways his head from right to left and back skipping to look at the audience in the middle of the gathering. Is he shy of making an eye contact with them or what?  Probably, a psychiatrist could shed some light on his such mannerism.
