Intermittent occlusion enhances the smoothness of sampled motion.

Discrete sequences of sampled motion often appear flickering and jerky. We present evidence showing that a target in sampled motion is perceived as smoother when structure in the background appears and disappears synchronously with the target. Specifically, we found that target flicker is turned into permanent target visibility at short interstimulus intervals and jerkiness is replaced by smoot...

Occlusion improves the interpolation of sampled motion

Several studies show that the perception of occlusion may affect various aspects of motion perception. Here we present data indicating that occlusion cues also influence the visual interpolation of sampled motion. Normally, sampled motion stimuli are perceived as less smooth and jerkier when the spatial gaps between successive presentations of the "moving" target stimulus increase. Adding surfa...

Apparent speed of sampled motion

Perceived speed was measured for stimuli moving unidirectionally in apparent motion with different sampling steps. The stimuli were displayed at successive locations for very brief durations (on-time = 1 msec). The basic result is an elevation of apparent speed produced by increasing the sampling step. This speed-up effect is maximal at low speeds (2 deg/sec), then progressively decreases with ...

Motion from occlusion.

Vision uses specific image features or cues to infer physical properties of the world. Here, we use a novel illusion to show that occlusion, traditionally thought of as a cue to depth, is also a powerful cue to motion. A display of stacking disks that contains only occlusion as a cue to depth generates a vivid sense of movement that is likely computed in early or middle levels of visual process...

Ocular following response to sampled motion

We investigate the impact of monitor frame rate on the human ocular following response (OFR) and find that the response latency considerably depends on the frame rate in the range of 80-160 Hz, which is far above the flicker fusion limit. From the lowest to the highest frame rate the latency declines by roughly 10 ms. Moreover, the relationship between response latency and stimulus speed is aff...
