Plants working as light sensors is exactly what Elowan was designed to convey—Deep integration of technology with our nature. One small capability such as response of plants to light shows how plants could be harnessed for our physical devices or interaction purposes.
This leads to applications such as sensing a surrounding environment through a plant or tree signals or routing those signals through our interactive devices. The plants could be used as sensing platforms for monitoring their own health, minute changes in the environment or to give rise to new organic interactive devices.
I think such a process of hybridizing with nature leads us to think about how we design our future devices. The way we have seen environment and sustainability efforts have been much more passive and always about saving while we are the back foot, but if we start looking at capabilities in the environment, we align ourselves with the development, as opposed to being divergent from it. I called this new type of interaction design as convergent design.
