WHAT IS THE MOCAP IDENT

MATLAB motion capture (mocap) projects the humanjoints and limbs of a subject in a 3D virtual space

The default human projection (left) closely resembles ahuman body: each marker and line connector iscorresponds to a human body part (i.e. lfemur, rradius).

For the theme: LIMITS +/- D.F. we chose to showcasedifferent extreme, abstract, and distorted representationsof the motion capture stick fig.

In altering the images, we wanted to dramatize thevirtual human identity and see how it would stack up tothe physical human

For standardizations, all body or environment distortionswere set on a walk motion amc file.

Is it still considered a

extreme level?

ANATOMICAL DISTORTION

Now maintaining marker and line weight, what happensif when we alter the anatomical values

The figure (right) has shrunken left and right tibia, femur,thorax, neck, feet and elongated radii

At first glancedoes this resemble a human?

TECHNOLOGY + IDENTITY:DISCUSSION

Although technology can capture human form and ones identity, thiscan also be easily manipulated via software.

Mocap distortions illustrate technologys ability to manipulate the charof our identity (identity).

Markers, lines, and joint contortions show the contrast between the figdegrees of freedom versus a humans fewer degrees of freedom

Changing the body and anatomy proportions changes-enhances-limits the range of mstick figure

Does the complement hold true? What does it look like? Is it similar tomovement?

Via these abstractions and optical illusionswe are interested in possexploring:1. Using dancers choreography/movement to create motion capture distort

2. Value the warped motion capture images as choreographic inspiration C
