Embodiments that relate to selectively filtering geo-located data items in a mixed reality environment are disclosed. For example, in one disclosed embodiment a mixed reality filtering program receives a plurality of geo-located data items and selectively filters the data items based on one or more modes. The modes comprise one or more of a social mode, a popular mode, a recent mode, a work mode, a play mode, and a user interest mode. Such filtering yields a filtered collection of the geo-located data items. The filtered collection of data items is then provided to a mixed reality display program for display by a display device.
