microForce: A user study about interaction with gestures in Augmented Reality.

microForce is a research project which investigates the use of gestural interaction in AR. It compares micro and macro gestures in terms of efficiency, productivity and user experience.

microforce: A Comparison of Macro and Micro Gestures
regarding the Manipulation of 3D Objects in Augmented Reality

Research Question

The paper discusses the pros and cons of mid-air macro gestures and rested micro gestures. Therefore we built a prototype in Unity. In the user study the user had to complete for exercises, all of them were common tasks  (select, scale, rotate, move) in the interaction with a 3D object in AR.

Research Paper

ABSTRACT

Gestures are an intuitive input method for Augmented Realitysystems which have become more and more desirable withthe technological advances in hand and finger tracking. AR-devices like the Microsoft HoloLens commonly use macrogesture interfaces which can cause fatigue and let the user feeluncomfortable when using them in public. These limitationscan be resolved by only using small motions with the wrist,palm and fingers – known as micro gestures. In this research,both gesture sets are compared regarding their efficiency,productivity and user experience for 3D operations byrunning a within-subject user study. The results show asignificant advantage in efficiency and productivity for thedefined micro gesture interface in complex operations likerotating and scaling. Only the move operation was performedbetter with the macro gesture set.
