Grasp, Grab or Pinch? Identifying User Preference for In-Air Gestural Manipulation
Alvin Jude, G. Michael Poor, Darren Guinness · 2016
In-air gestural interactions can be used in desktop or other similar systems to perform cursor-based movements typically done with a mouse. One form of interaction that is required here is that of gestural manipulation, such as the ability to select a target and then move or rotate it, or any other forms of manipulation. In this paper, we implemented and evaluated 3 different gestures for users to manipulate objects on a screen, which we referred to as "grasp," "grab" and "pinch." We performed a usability study, which showed a strong preference for the "grasp" gesture.
