1. A method of operating a virtual image generation system, the method comprising: allowing an end user to visualize an object of interest in a three-dimensional scene; spatially associating a text region within a field of view of the user, wherein the text region is spatially associated with the object of interest; generating a gesture reference associated with the object of interest; generating a textual message that identifies at least one characteristic of the object of interest; streaming the textual message within the text region; sensing gestural commands from the end user by detecting an angular position of an anatomical part of the end user relative to a plurality of different regions of the gesture reference; and controlling the streaming of the textual message in response to the sensed gestural commands, wherein the gesture reference is an annular ring surrounding the object of interest, and wherein a first side of the annular ring forms one of the different regions, and a second side of the annular ring opposite of the first side of the annular ring forms another one of the different regions.
