The disclosed technology is generally directed to mixed reality devices. In one example of the technology, a mixed-reality view is provided to an operator. The mixed-reality view includes both a real-world environment of the operator and holographic aspects. The holographic aspects include at least a first hologram. The first hologram is displayed with a first hologram menu, such that the first hologram menu includes visible selectable menu options associated with the first hologram. In the mixed-reality view, the first hologram menu, including the visible selectable menu options of the first hologram menu, is rotated to face the operator as the operator moves, such that the first hologram menu rotates in a curved manner about the first hologram as the first hologram menu rotates. Responsive to the operator making a selection on the first hologram menu, the first hologram in the mixed-reality view is altered based on the selection.
