What is the difference between pointing and touch bar activation?

Pointing can be used for reading any text.  A single tap of the touch bar should only be used to read simple texts such as a typed memo, a printed letter, a sign on a door, or a simple page of a book.

IMPORTANT:  When reading text in a complex field such as a magazine article, newspaper article, or computer screen (all of which typically have advertisements, sidebars, etc.), the pointing gesture MUST be used since the purpose of the gesture is to hone the device’s attention in on the specific block of text at which the finger is pointing.  If a single tap of the touch bar is used for any of the above examples of text, then the device will attempt to read everything in view, which will usually not result in a productive or efficient outcome.
