Demos & Experiments
(Many of these demos had been implemented with Macromedia Flash. Unfortunately, some browsers are not longer supporting this technology)
Guess the sex
In this experiment, you’ll be shown point-light animations of humans doing various actions. Your job will be to guess whether they are male or female.
BMLgender
Analysis of sex-specific differences in walking style reveals that the dynamic part of the motion contains more information about gender than motion-mediated structural cues.
Size and Speed Demo
Gravity and its Role in Biological Motion Perceptions Gravity links spatial and temporal aspects of the behaviour of objects in our visual environment. Gravity also imposes constraints on moving animals. Our visual system employs knowledge about these constraints in order to detect, perceive and adequately interpret biological motion. Psychophysical experiments show how this is achieved. […]
BML Scrambled: Direction from scrambled motion
This interactive animation contains stimuli that demonstrate our ability to derive information about the direction from scrambled biological motion. If the stimulus is inverted performance declines to chance level. For details, read these papers (Troje & Westhoff, 2006, Troje & Chang, 2013).
BML Rating
Derive your own attributes! This demo allows you to derive your own axis in motion space. You will be prompted to input whatever attribute you are interested in.
BML Walker (Old version)
Biological motion contains information about sex, weight, emotional state and personality traits. Based on the walking patterns of 100 individual walkers, we derive dimensions that reflect how walking changes as a function of biological and psychological attributes. The BMLwalker was first published as part of a paper that appeared in 2002 in the Journal of […]
