In this question the student must explain that Semiotic gestures are easier for algorithms to understand due to how they represent concepts based with the algorithm itself. For example symbolic gestures represent a know gesture the the algorithm can store and use as a reference. A Deictic gesture is referring to a command gesture that is easy to store as well like pointing at an object. A Iconic gesture show how to manipulate a virtual object within the software like the unsqueeze motion would increase size of an object. They should also use a contrast of these semiotic gestures against Ergotic & Epistemic gesures.
