Cooperation of Virtual Reality and Real Objects with HoloLens

We propose several approaches when programming applications for Microsoft HoloLens. These applications aim at close cooperation of real world with holographic objects (virtual reality). Often a precise placement that does not change with the position of a user can be challenging. One way of avoiding such problems is to use technology of anchors. Another way proposed in this paper is a prior scanning of object of interest with an application aimed for Vuforia plugin. Both concepts use close cooperation with user-friendly environment for developing of mixed reality applications - Unity. We present and discuss examples in this article. The area of precise location for mixed reality (augmented reality mixed with real reality in a way that one can interact witch each other) is of paramount importance. If we know precise position of virtual objects in the scene and precise position of the device in the scene, we can alleviate the burden of massive computing within HoloLens. As a result, we gain better experience from mixed reality.
