  Immersive environments have gradually become standard for visualizing and
analyzing large or complex datasets that would otherwise be cumbersome, if not
impossible, to explore through smaller scale computing devices. However, this
type of workspace often proves to possess limitations in terms of interaction,
flexibility, cost and scalability.
  In this paper we introduce a novel immersive environment called Dataspace,
which features a new combination of heterogeneous technologies and methods of
interaction towards creating a better team workspace. Dataspace provides 15
high-resolution displays that can be dynamically reconfigured in space through
robotic arms, a central table where information can be projected, and a unique
integration with augmented reality (AR) and virtual reality (VR) headsets and
other mobile devices. In particular, we contribute novel interaction
methodologies to couple the physical environment with AR and VR technologies,
enabling visualization of complex types of data and mitigating the scalability
issues of existing immersive environments.
  We demonstrate through four use cases how this environment can be effectively
used across different domains and reconfigured based on user requirements.
  Finally, we compare Dataspace with existing technologies, summarizing the
trade-offs that should be considered when attempting to build better
collaborative workspaces for the future.
