Increasingly, dedicated immersive devices become available that were specifically created to be used in a mobile fashion. At the consumer end, Google Cardboard1 pioneered the notion of a simple holder and lenses to turn a modern smartphone into a VR headset. For professionals, commercial AR systems like Microsoft HoloLens are fully self-contained computing devices with dedicated graphics and computer vision hardware to provide stable augmented reality data overlays. These devices represent opportunities for new applications for 3D mobile data visualization that will permeate the way we work or potentially, our personal lives, as discussed in Section 4.9.
Human performance and mental workload in augmented reality: brain computer interface advantages over gestures

The different tasks were implemented using the Microsoft HoloLens (Microsoft Corporation, United States) as the AR HMD. The Microsoft HoloLens is the first HMD running Windows Mixed Reality under Windows 10, which supports Universal Windows Platform (UWP) apps. The Microsoft HoloLens is based on an Intel 32-bit architecture with TPM 2.0 support. It is equipped with 64 GB of flash memory and 2 GB of RAM; the network connectivity features Wi-Fi 802.11ac and Bluetooth 4.1 LE. The mounted sensors are 1 inertial measurement unit, 4 environment understanding cameras, 1 depth camera and a 2MP photo/HD video camera. The display has a holographic resolution producing 2.3 M total light points and a holographic density greater than 2.5k radiants. The device capabilities are Gaze Tracking, Gesture Input and Voice Support [27].

AR refers to the addition of virtual objects into the real world that appear to coexist in the same space as the user (Azuma, 1997). This contrasts with VR where virtual objects are displayed within a virtual (rather than real) environment (Milgram & Kishino, 1994). Both technologies allow for interactive visualization of 3D content, with the former being more recently applied in an untethered head-worn format. The so-called standalone head-worn AR systems neither connect to nor depend on an external computer for processing, permitting their use in a variety of mobile contexts. Of the available head-worn consumer-grade AR technology available today, the Microsoft HoloLens stands out as the most mature, providing rich 3D graphical content, markerless inside-out tracking, wireless network connectivity enabling collaborative AR experiences, and support for gestural and voice command interaction with digital content in a self-contained headset. These features have made HoloLens an attractive tool for researchers investigating the utility, usability, and cognitive impact of standalone AR systems. Indeed, recent research has used the HoloLens to investigate a variety of use cases, including driving (Kun, van der Meulen, & Janssen, 2017), manual assembly (Blattgerste, Strenge, Renner, Pfeiffer, & Essig, 2017), network operations monitoring (Beitzel et al., 2016; Beitzel, Dykstra, Toliver, & Youzwak, 2018), data visualization (Hockett & Ingleby, 2016; Saenz, Baigelenov, Hung, & Parsons, 2017), and medical imaging (Cui, Kharel, & Gruev, 2017; Hackett & Proctor, 2016; Karmonik, Boone, & Khavari, 2017).

Microsoft HoloLens is a mixed reality glasses. We used Unity 2018.4 and Mixed Reality Toolkit1 for the implemented application for Universal Windows Platform (UWP). The Toolkit includes basic scripts and examples for the accelerated creation of applications for HoloLens. To connect glasses to ROS, we used RosSharp2 for UWP, which we had modified by adding new message types that we employ in ROS.
