ABSTRACT
Since the onset of cinematic virtual reality (cine-VR), one technique that has proven helpful in drawing the viewer's attention is a graphical overlay. This chapter explains how the author arrived at constructing a spherical grid to map various safe areas for graphic overlay placement. The graphics overlay within that range can be perceived with ease and comfort. In placing text overlay (intertitles or subtitles), The New York Times seems to prefer the latter, but the author reckon it does not really matter as long as they are constant. In VR documentaries where intertitles (or subtitles) are an integral part of the narrative, three orientation points work best, especially if the viewers are watching in a sitting position. While the ideal text size for reading in print is between ten and twelve points, in VR, the safest minimum body text size is twenty-four points.
