We know from research that speakers gaze at the objects they refer to just before pointing and verbally naming the objects. Listeners on the other hand, look at the referred objects shortly after seeing the speaker point and refer to the objects. Displaying the speakers’ gaze to the listeners could help them better attend to references, which in turn could enhance their understanding.
