Abstract

This paper describes the integration of augmented-reality-glasses into a helicopter simulator with front projection. Therefore the Microsoft HoloLens is used as a head-mounted-display for pilots. The paper focuses on the fundamental integration with the encountered problems and related solutions. In a simulator, the projection of the outside world causes multiple errors regarding the position of the objects, such as distances from the eye. A proposed solution to these errors is the repetition of the projection transformation at the glasses, thus doing the same errors to match the projected outside world. Another problem arises with the need of head-fixed holograms on the HoloLens. They are very shaky and they fan out. To solve, a non-linear filter is proposed. The drawing of lines, as the graphic core element, is investigated to find a tradeoff between good aesthetics and sufficient frames-per-second. Furthermore a method for calibration is proposed to align the holograms with the world, and save or load the result. The overall quality of the system is excellent. It is extremely cost-effective and got very positive feedback from pilots and engineers.
