Reducing Popping into View of Objects and Detail in Area‐of‐lnterest Displays

Summary Eye‐coupled area‐of‐interest displays may offer an alternative to more traditional multichannel simulator displays at a fraction of the cost but with the same or better resolution. Developers of any new system must concern themselves with potential limitations of the new devices; a potential issue for area‐of‐interest displays is “popping.” Popping is the compelling phenomenal appearance of new scene content, as it passes from low levels of detail available in the periphery, or background, to the high levels of detail with the area‐of‐interest. The results of these experi ments suggest that popping will be more pronounced for lower spatial frequencies (larger sizes); that popping depends upon the slope of the temporal onset and offset of the high level of detail material; and finally that popping is more apparent with more frequent changes in level of detail. From these findings we derive recommendations for minimizing popping. These results can also be translated into general principles describing how to make display changes conspicuous or inconspicuous.
