A comparative study of 2D and 3D mobile keypad user interaction preferences in virtual reality graphic user interfaces
Akriti Kaur, Pradeep G. Yammiyavar · 2017
Graphical User Interfaces (GUI) on mobiles involves user interaction of touch input on a 2D surface. With advances in Augmented/Virtual Reality, possibilities of 3D GUIs will emerge. However, 3D GUIs do not have many design heuristics. This paper reports an experiment by collating quantitative and qualitative responses from 15 users, to explore usability problems that are likely to be encountered when a 2D interface element such as number keypad is replaced with a 3D element interface in Virtual reality. Would an interface with 3D elements perform better than the existing 2D GUIs is a moot research question? The results indicate user motivation towards using the interface inspired from 3D elements. The paper discusses issues of interaction in 2D and 3D virtual spaces with their possible implications for upcoming 3D VR environments.
