User Preferences for Interactive 3D Object Transitions in Cross Reality - An Elicitation Study
Nanjia Wang, Daniel Zielasko, Frank Maurer · 2024
The paper investigates how users want to transfer 3D virtual objects between a standard desktop monitor and an augmented reality head-mounted display setup during a Cross Reality session. An elicitation study with 20 participants was conducted to gather their preferred interactions and input modalities to select 3D virtual objects and trigger the transition. Participants were allowed to propose interactions belonging to various input modalities or a combination of interactions that utilize multiple input modalities. We labeled the observed data and analyzed the resulting 1200 input observations to derive a set of recommended interactions. We found that mid-air hand gestures Drag, Tap, and Grab were the most commonly proposed interactions and should be considered as the primary interaction for CR virtual objects transition assisted with other interactions and input modalities as the supplementary base on different user scenarios.
