As the visitor walks up to the podium, a laser-cut instructional panel guides the visitor to hover her hands above a LEAP Motion Device. The LEAP Motion Device can track hand gestures, and differentiate whether the user is grasping their hands or pinching.
If the user finds a stranger, friend, or family to work together and grasp their hands synchronously, the Arduino-controlled motor successfully waters the plant. The plant continues to live. As strangers or friends, they have worked together to keep the plant alive. Without this collaboration, the plant withers.
