Perceptual Load in the Kitchen: Measuring Distraction in Immersive Virtual Reality

X O O N O O O K M Z N H X W

Perceptual Load Theory: Distraction is stronger when perceptual load is low, rather then high.

Perceptual Load - Experiment

Congruent Incongruent Low Load

(target=soda)

High Load

(target=yogurt)

  • User searched for target within the circle (soda or yogurt)
  • Flanker (congruent or incongruent) had to be ignored.
  • Perceptual load was manipulated by the color of the distractors.

24

slide-25
SLIDE 25
  • Contrary to theory, distractor effect not modulated by load.
  • Use VR to test traditional research, in complex ecologically valid scenarios.
