Bringing a colored head-down display symbology heads up: Display fidelity review of a low-cost see-through HMD

Kurzfassung

Within the U.S.-German project agreement on advanced technology for rotorcraft (PA ATR) DLR conducts research on pilot aids for helicopter operations in DVE. For example, an HMD can provide visual cues to the pilot while flying eyes-out. With the HoloLens 2 as a low-budget device, we can rapidly prototype new symbology and make use of its full-color waveguide display. As a first step, this paper aims to investigate how the color of DLR's symbology needs to be adapted when shown on the HoloLens 2 and what kind of information is beneficial when presented on an HMD or should remain on a head-down display.
