Interacting with digital lighting systems opens new opportunities and challenges, especially when those systems are connected to the Internet of Things (IoT). This workshop aims at investigating richer interactions with interconnected lights. We strive for interactions that happen in our everyday environments and that go beyond not only swiping and tapping on a screen, but also the mere tangible switch. This workshop will be an opportunity to discuss and practice novel interactions with light, exploring human bodily and cognitive skills to grasp better the ephemerality of light and of the IoT.
