  The volumetric representation of human interactions is one of the fundamental
domains in the development of immersive media productions and telecommunication
applications. Particularly in the context of the rapid advancement of Extended
Reality (XR) applications, this volumetric data has proven to be an essential
technology for future XR elaboration. In this work, we present a new multimodal
database to help advance the development of immersive technologies. Our
proposed database provides ethically compliant and diverse volumetric data, in
particular 27 participants displaying posed facial expressions and subtle body
movements while speaking, plus 11 participants wearing head-mounted displays
(HMDs). The recording system consists of a volumetric capture (VoCap) studio,
including 31 synchronized modules with 62 RGB cameras and 31 depth cameras. In
addition to textured meshes, point clouds, and multi-view RGB-D data, we use
one Lytro Illum camera for providing light field (LF) data simultaneously.
Finally, we also provide an evaluation of our dataset employment with regard to
the tasks of facial expression classification, HMDs removal, and point cloud
reconstruction. The dataset can be helpful in the evaluation and performance
testing of various XR algorithms, including but not limited to facial
expression recognition and reconstruction, facial reenactment, and volumetric
video. HEADSET and its all associated raw data and license agreement will be
publicly available for research purposes.
