“…Datcu and Lukosch [19] also presented AR freehand interactions in a crime scene investigation application, showing novel methods in freehand interactions, however the analysis of accuracy was limited to pointing interactions only. Freehand grasping in an AR context, without the use of wearable devices, has been presented in [1]. Findings from this work stated that the freehand interaction alongside the visual feedback increased the feel of grasping for users.…”

“…Within Mixed Reality (MR), freehand grasping is the manual grip between a (real) user and a (virtual) object without the utilisation of wearable sensors. In many applications this form of interaction is preferable due to the discomfort of wearable devices (Suzuki et al [1]) and the often time consuming configuration and user adaptation (Holz et al [2]) of them. Moreover, recent studies notably Ponto et al [3], have illustrated that wearable methods of user feedback, notably biofeedback or electromyograms (EMG), can aid in human grasping, but often cause fatigue and discomfort.…”

This article presents an analysis into the accuracy and problems of freehand grasping in exocentric Mixed Reality (MR). We report on two experiments (1710 grasps) which quantify the influence different virtual object shape, size and position has on the most common physical grasp, a medium wrap. We propose two methods for grasp measurement, namely, the Grasp Aperture (GAp) and Grasp Displacement (GDisp). Controlled laboratory conditions are used where 30 right-handed participants attempt to recreate a medium wrap grasp. We present a comprehensive statistical analysis of the results giving pairwise comparisons of all conditions under test. The results illustrate that user Grasp Aperture varies less than expected in comparison to the variation of virtual object size, with common aperture sizes found. Regarding the position of the virtual object, depth estimation is often mismatched due to under judgement of the z position and x, y displacement has common patterns. Results from this work can be applied to aid in the development of freehand grasping and considered as the first study into accuracy of freehand grasping in MR, provide a starting point for future interaction design.

“…This decomposition in three phases of the touching interaction could also be applied to another common hand-based interaction in XR environments: grasping. Grasping can be bare handed or not, as one of the di erences between VR and AR is the fact that AR favors controller-free interactions [31,35]. Within MR, freehand grasping is the manual grip between a (real) user and a (virtual) object without using wearable sensors.…”

“…Previous work on how to move virtual objects with bare hands in immersive environments has been conducted. Suzuki et al [29] introduced an AR system to grab a virtual object with bare hands using the pinch gesture. The authors generate composite images to achieve occlusion of the virtual object by the real hand.…”
