New Wearable Technology Can Sense Appliance Use, Help Track Carbon Footprint

A new wearable technology developed at the University of Washington called MagnifiSense can sense what devices and vehicles the user interacts with throughout the day, which can help track that individual’s carbon footprint, enable smart home applications or even assist with elder care.

In today’s smart home, technologies can track how much energy a particular appliance like a refrigerator or television or hair dryer is gobbling up. What they don’t typically show is which person in the house actually flicked the switch.  A new wearable technology developed at the University of Washington called MagnifiSense can sense what devices and vehicles the user interacts with throughout the day, which can help track that individual’s carbon footprint, enable smart home applications or even assist with elder care.   In a study to be presented this week at the 2015 ACM International Joint Conference on Pervasive and Ubiquitous Computing, MagnifiSense correctly classified 94% of users’ interactions with 12 common devices after a quick one-time calibration, including microwaves, blenders, remote controls, electric toothbrushes, laptops, light dimmers, and even cars and buses. Even without the calibration, MagnifiSense was still correct 83% of the time.   The sensor worn on the wrist uses unique electromagnetic radiation signatures generated by electrical components or motors in those devices to pinpoint when its wearer flicks a light switch, turns on a stove or even boards a train.    “It’s another way to log what you’re interacting with so at the end of the day or month you can see how much energy you used,” said Shwetak Patel, Washington Research Foundation Endowed Professor of Computer Science & Engineering and Electrical Engineering, who directs the UW Ubicomp Lab.
