The way we perceive the visual motion of objects as we move is a phenomenon called 'optic flow.' Now, Brown University researchers have discovered that optic flow helps us to walk. They've used ...

The cover of the Dec. 4 issue of Current Biology features breakthrough research in optic flow conducted by William Warren, professor and chair of the department of cognitive and linguistic sciences.

The way objects appear to stream by us as we move through the world is a phenomenon called optic flow. Think of the street signs and storefronts that sail across the car windshield as we drive. That's ...

PROVIDENCE, R.I. [Brown University] — The motion we perceive with our eyes plays a critical role in guiding our feet as we move through the world, Brown University research shows. The work was ...

Birds use a trick of the eye called “optic flow” to zip through forests without colliding. How do birds manage to fly through narrow spaces without constantly bumping into trees or buildings? It turns ...

Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...

Most modern aircraft, cruise missiles, spacecraft – in fact, almost all flying vehicles – use an accelerometer for flight stabilization. Living creatures that fly, on the other hand, rely on their own ...

In everyday life, the optic flow associated with the performance of complex actions, like walking through a field of obstacles and catching a ball, entails retinal flow with motion energy (first-order ...

How do birds manage to fly through narrow spaces without constantly bumping into trees or buildings? It turns out that they use a trick of the eye called optic flow. Understanding what optic flow is ...
