We hear about the saving and the wasting of energy all the time. It seems like we don’t actually pay attention until it affects us in the real world. Which is how this light switch helps. Peter Russo and Brendan Wypich of Stanford University developed the SmartSwitch, a light control with tactile feedback that helps you “see” how much energy is already being used, whenever you try to flick the switch.
If the total energy consumption in the house is low, the SmartSwitch is easy to flip. But if the consumption is higher, the SmartSwitch is physically harder to flip, thanks to a brake pad within the mechanism. The idea is that people will use this tactile feedback to decide if they really really need that light on or not. And it gives users a physical interaction with how much they are using.
