Home is the place where a person can rest, de-stress, and have a moment of peace. But sometimes, the place in which we call “home” can be more stressful than any other place, including the office, because of the countless household chores that we have to do. Ever since this realization, we humans have tried to figure out ways that would make chores a little bit easier.
One of the concepts that has prevailed over the years is the concept of house automation, or a smart home. But for Cheng Zhang, it would be very difficult to have such a home.
"In order to have a smart home at this point, you'd need each device to be smart, which is not realistic; or you'd need to install separate sensors on each device or in each area,"
This is why Zhang and a group of scientists developed a device that could move the concept of a smart home closer to reality.
The device, called VibroSense, uses lasers to capture subtle vibrations in walls, ceilings and floors, as well as a deep learning network that models the vibrometer's data to create different signatures for each appliance—bringing researchers closer to a more efficient and integrated smart home.

The device showed nearly 96% accuracy in identifying 17 different activities across five houses—including dripping faucets, an exhaust fan, an electric kettle, a refrigerator and a range hood—in five houses over two days, according to the paper. VibroSense could also distinguish five different stages of appliance usage with an average accuracy more than 97%.

Among other uses, the system could help homes monitor energy usage and potentially help reduce consumption.
