Telepresence technology may soon appear in the home where changing light conditions could make it difficult to portray a person well on video. This research investigated whether the amount of telepresence fill light required for a well-lit appearance was enough to cause discomfort glare. Thirty participants adjusted the output of two fill lights: one in front of them (focusing on discomfort) and one in front of the remote telepresence user (focusing on appearance). Ambient light levels (48-71 lux, 118-130 lux, 269-281 lux) and fill-light positions (top of display, 30.5 cm higher) were varied. For all conditions, the amount of light required to produce a pleasing portrayal was greater than that at the point of discomfort. The mean discomfort threshold was the same for all ambient light conditions (663.46 cd/m 2, 8.44 lux at 2.44 m), possibly because background luminance did not change enough. The amount of light that produced a well-lit appearance was about the same for dim and moderate ambient light (3,348.65 cd/m 2, 51.61 lux at 2.44 m) but lower for bright ambient light (1,204.47 cd/m2, 17.81 lux at 2.44 m). Raising the light source did not affect discomfort but did require more light for a good portrayal. Technology providers should consider collocating the fill light with the display, limiting its luminance to 663.46 cd/m2 for low-light environments similar to this research, and raising or lowering that limit as the background luminance changes.
