User-Centered Prototyping for Single-User Cross-Reality Virtual Object Transitions

Cross-reality is a newly emerged research field that studies the transition and current usage of multiple systems along Milgram's Reality-Virtuality Continuum(RVC). Our research currently focuses on studying how the user could interact with CR applications and move virtual objects along Milgram's RVC. The prototype is an embodiment of an application and can be used to gain insights and knowledge. We build low-fidelity and high-fidelity prototypes to study the transition of 3D virtual objects. However, We face challenges since cross-reality involves more than one space on the RVC, so when designing the prototype, researchers and designers can not refer to their previous experience and interaction metaphor from a space they are familiar with, such as physical, AR, or VR space. Thus we plan to conduct elicitation studies to gain more knowledge and insights to serve as a benchmark to guide the design of the prototypes.
