Abstract : Progress over the past year has been rapid and wide ranging, covering two primary areas. First, in the area of visual attention, we have shown both the existence of a sustained and a transient component of enhanced pattern recognition. This cannot be explained by visual transients or eye movements. Second, we have examined a wide range of issues related to partial visibility (occlusion) using stereoscopic displays. In particular, we have shown that pattern recognition of partially hidden objects is superior if the pattern is in a rear vs. front stereoscopic plane, that the solution to the aperture problem for motion is dictated by whether line terminators are seen as real terminators or the result of occlusion by other surfaces, and finally, we have shown that the depth interpretation of untextured stereograms requires that the visual system edges before evaluating their depth.
