ABSTRACT
Pointing with the index finger is a vital part of human communication. Index-finger pointing, which often co-occurs with speech, is characterized by an arm and index finger extended to the direction of an interesting object, with the other fingers curled under the hand and the thumb held down and to the side. We point at things we know and things we have never seen before. Pointing can be a way of declaring, making a point, or asking. The underlying intention is always to draw someone else’s attention to an object or event of interest.
