AbstractWe report on three ongoing human-powered interactionexplorations with a focus on batteryless interactions using hand cranking movements. Importantly, our explorations concerned not only the matter of powering but also using human physical engagement for controlling interactive systems, and how to support designers in testing, exploring, and making such interactions. The three demonstrators consist of a) a hand cranked quote reader, b) an email sending device, and 3) a new bit for exploring this mode of interaction within the LittleBits ecosystem.
