What is the moving room paradigm?

What is the moving room paradigm?

We couple these intrinsic dynamics to visual information that stabilizes posture in the visual world. This leads to a theory of postural sway induced by an optic flow field (“moving room” paradigm). The optic flow is parametrized in a simplest approximation by the expansion rate of a relevant perceptual target.

What does the swinging room experiment show?

… Indeed, the specification of ecological self as a global transformation of optic flow was cleverly demonstrated by David Lee’s now classic “swinging room” research. Lee (Lee and Aronson, 1974; Lee and Lishman, 1975) constructed a room with a fixed floor, but with walls and ceiling that can be swung back and forth.

What is global optic flow?

Sequences of ordered images could provide the estimation of motion as either instantaneous pixel velocities or discrete-time image displacements. In the proposed method, we have calculated global optical flow, which is a single optical flow value for the whole image.

What is optic flow in psychology?

Optic Flow. Optic flow can be defined as the motion of all the surface elements from the visual world. As you move through the world, the objects and surfaces within the visual environment flow around you. The human visual system can determine your current direction of travel from the movement of these surfaces.

What is movement parallax?

Motion parallax refers to the fact that objects moving at a constant speed across the frame will appear to move a greater amount if they are closer to an observer (or camera) than they would if they were at a greater distance.

What is induced motion in psychology?

an illusion of movement that occurs when a small stationary stimulus is surrounded by a large moving stimulus. The small object appears to move, while the large object appears to be still. An example is the haunted swing illusion.
