Sym-Ulations allows participants to explore the asymmetry of their own faces.It also allows them to use their own face to create humorous impossible faces.
User Interaction:
The user holds a "Setup" button and sees a mirror image of his face on a video monitor. A dotted line runs down the center of the monitor indicating the symmetry point. When the button is released the image is instantly frozen and manipulated based on the current mode or the machine.
The manipulations are:
* L/R - a mirrored image.
* R/L - a non-mirrored image the way others see you.
* L/L - left side repeated.
* R/R - right side repeated.
* All four images at once for comparison.
