A field-sequential color projection system displays color images using a single panel and a color filter wheel. The wheel spins very rapidly, and creates a sequence of red, green, blue, and white images that combine to create a single full-color image. Although the use of a single panel can reduce both projector size and costs, the field-sequential color projection mechanism causes the observer to perceive trichromatic separation during times of rapid eye movement. This phenomenon is called "color breakup". We examine the characteristics of saccadic eye movement, which result from viewing images containing color breakup. We describe two experiments that were conducted to examine the effects of color breakup as manifested through the ergonomic indices of eye movement and the subjective symptoms of asthenopia.
