While we live in a three dimensional world with the ability to broadcast ourselves — to everyone and no one at once — whenever we engage with our phones, we enter a fourth dimension, according to author Laurence Scott.

In his new book, "The Four-Dimensional Human: Ways of Being in the Digital World," Scott explores how technology influences our daily lives and our actions.
