GrabIt Hiroshi Ishii, Angela Chang, Adam Kumpf
GrabIt allows users to collaboratively explore the principles of power generation, transfer, and consumption via tangible wooden sticks. Pushing on one stick generates power that is transfered to other sticks in real time allowing users to see, and feel, the effects of losses and electrical loading. All energy in the GrabIt system is derived from its users and therefore makes the mapping between input, output, and losses transparent. Variable-color light bulbs can also be connected to the system to serve as simplified voltage indicators during use.
