Query: Pose2Room: Understanding 3D Scenes from Human Activities   With wearable IMU sensors, one can estimate human poses from wearable devices
without requiring visual input \cite{von2017sparse}. In this work, we pose the
question: Can we reason about object structure in real-world environments
solely from human trajectory information? Crucially, we observe that human
motion and interactions tend to give strong information about the objects in a
scene -- for instance a person sitting indicates the likely presence of a chair
or sofa. To this end, we propose P2R-Net to learn a probabilistic 3D model of
the objects in a scene characterized by their class categories and oriented 3D
bounding boxes, based on an input observed human trajectory in the environment.
P2R-Net models the probability distribution of object class as well as a deep
Gaussian mixture model for object boxes, enabling sampling of multiple,
diverse, likely modes of object configurations from an observed human
trajectory. In our experiments we demonstrate that P2R-Net can effectively
learn multi-modal distributions of likely objects for human motions, and
produce a variety of plausible object structures of the environment, even
without any visual information.
