ECVP Paper Perception of phase wave motion We shall describe a new class of motion stimulus, containing phase
wave motion. The stimulus consists of a 2-D array of pattern elements.
Each element oscillates in position over the same distance. When all
elements oscillate in-phase, the pattern moves rigidly back and forth.
When the relative phase of oscillation varies progressively across the
pattern, a travelling wave of oscillation can be created that has the
appearance of a fabric blowing in a breeze. Observers readily perceive
the direction and speed of the phase wave, even though it contains no
motion energy that can be detected by low-level motion processes, other
than the local element oscillation. The paper will present some initial
psychophysical data and review possible explanatory models based on
texture processing and second-order motion processing.

ECVP Poster Motion perception in art and design research What happens when visual perception theory and practice become a tool
for art and design? How can the science of vision be interpreted in
such as way as to provide new techniques for drawing and animation?
We will present the outcome of research from an art and design perspective
that uses science as both inspiration and problem solver. From exhibitions
in the UK, Europe and Korea, we will show biological motion used to
create an illusory army of figures marching around a quarry wall; path
guided apparent motion to provide a means of providing low-bandwidth
mobile phone media; and how depth and motion can be used to create a
new way of drawing. In addition we will introduce a new research program
where we are investigating how new physical forms can be created using
visual motion perception.
