Abstract	This paper presents a first study into the use of dual view visual feedback in an exocentric MR environment for assisting freehand grasping of virtual objects. Recent work has highlighted problems associated with user errors in freehand grasping, via an analysis of virtual object type, location and size. Our work presents an extension to this, where 30 participants are recruited for two experiments (one assessing object size and the second object position), giving 1710 grasps in total. We report on results following the same protocol of the aforementioned study using a dual view visual feedback method. Results show that dual view visual feedback significantly increases user z placement accuracy and improves grasp placement in the x and y axes, however completion time is significantly higher. No improvement was found in user grasp aperture using dual view visual feedback for changes in object size and position.
