Here we see Obama give more than a handshake by touching the family member's arm it creates another touch connection, which conveys more emotion.

There are different degrees of emotion even in an handshake, there is hands only; and the free hand touches forearm or upper arm; there is the free hand on the shoulder; and there is the free hand enclosing the hands that are shaking in a "hand hug." Each progressively conveys more emotion and attachment.◦
