The modern family
Children these days are so comfortable with technology that seeing themselves or a family member on the screen is no big deal. Neither is talking to someone on the other side of the world or speaking into a machine. Nigel knows how to use the tablet pen to "send" (wacky) drawings over the instand messenger while having the audio and video conference going on.
They've grown up surrounded by these capabilities and it's become part of their lives. This is their world.
