Hiding graphic updates during long saccadic suppression periods. Herpers, R., Schumacher, J., & Allison, R. In Dynamische Perception 2004, pages 77-82, 2004. Infix- IOS Press BV Amsterdam. -1 abstract bibtex Abstract. During visual exploration of a scene human beings can be insensitive to even large changes in the scene when the eye is executing rapid or saccadic eye movements. In this contribution, this period of saccadic suppression was exploited to hide graphics updates in immersive environments. Two experiments were conducted. In the first experiment the general sensitivity of observers to trans -saccadic translations of large images of complex natural scenes was studied. It was found that trans -saccadic changes of up to 1.2 degrees of visual angle were seldom noticed during saccades with duration of at least 66 ms. In the second experiment, the perceived magnitude of trans -saccadic translation was compared to the perceived magnitude of image translation when no saccade was performed to determine the point of subjective equality. It was found that trans-saccadic displacements were perceived as approximately half as big as equivalent sized inter-saccadic displacements.
