Sci-Fi-Inspired Interaction and Evaluation of the Memory Orb

The memory orb is a cylindrical input device for virtual reality, inspired by a science-fiction artifact. This paper extends previous work by presenting a use case, interactions, and a user study directly grounded in a movie scene, guiding the design of hovering, selecting, translating, rotating, and scaling 3D objects. Results show performance comparable to traditional virtual reality controllers and positive user reception, supporting further exploration of this novel, fiction-inspired interface.
