Check out Lauren Wang’s #UIST2025 poster on GhostObjects: life-size, world-aligned virtual twins for fast and precise robot instruction, with real-world lasso selection, multi-object manipulation, and snap-to-default placement.

This is the first piece in her ongoing work on #AR for #HRI 🤖👓 @hci

A user in AR lasso-selects a pile of books and boxes on the floor, which generates GhostObjects—virtual twins colocated with the real objects. The user then drags the GhostObjects along a trajectory, snapping them into their default shelf positions. And then the robot enters the scene and physically places them on the shelves afterwards.
