Abstract
The repetitive scanpath eye movement, EM, sequence
enabled an approach to the representation of visual images in the
human brain. We supposed that there were several levels of
binding--semantic or symbolic binding; structural binding for the
spatial locations of the regions-of-interest; and sequential binding for
the dynamic execution program that yields the sequence of EMs.
The scanpath sequences enable experimental evaluation of these
various bindings that appear to play independent roles and are likely
located in different parts of the modular cortex. EMs play an essential role in top-down control of the flow of visual information. The
scanpath theory proposes that an internal spatial-cognitive model
controls perception and the active looking EMs. Evidence supporting the scanpath theory includes experiments with ambiguous figures, visual imagery, and dynamic scenes. It is further explicated in
a top-down computer vision tracking scheme for telerobots using
design elements from the scanpath procedures. We also introduce
procedures--calibration of EMs, identification of regions-of-interest,
and analysis and comparison programs--for studying scanpaths.
Although philosophers have long speculated that we see in our
mind's eye, yet until the scanpath theory, no strong scientific evidence was available to support these conjectures.
