Mixing Molecules is a full-body immersive simulation demonstrating the collision of molecules at the nanoscale. The digital interface allows visitors to use their shadows to “push” animated molecules that are projected onto a screen in a darkened room. Visitors can manipulate the collsion of the molecules, speeding or slowing the formation of new compounds. The piece demonstrates the connection between the nanoscale - where individual molecules collide with each other - and the macroscale where many small random collisions appear as one larger, consistent motion.
Three Drops is a full body immersive simulation that allows visitors to interact with water at three size scales using their shadows. At each scale, different physical forces can be observed. At the macro (human) scale, where gravity is the noticeable force, visitors are showered with water drops from a simulated shower. At the microscale--one thousand times smaller--where surface tension becomes more apparent, visitors play with a beach-ball sized water drop.
A formative evaluation was conducted on Three Drops, an Immersive Digital Interactive (IDI), that allows visitors to interact with simulations of water at different size scales where different physical forces dominate. This evaluation revisits the exhibit after changes were made to address issues identified in the first series of formatives.
