We've become accustomed to our smartwatches and smartphones sensing what our bodies are doing, be it walking, driving or sleeping. But what about our hands? It turns out that smartwatches, with a few tweaks, can detect a surprising number of things your hands are doing.
Researchers at Carnegie Mellon University's Human-Computer Interaction Institute (HCII) have used a standard smartwatch to figure out when a wearer was typing on a keyboard, washing dishes, petting a dog, pouring from a pitcher or cutting with scissors.
By making a few changes to the watch’s operating system, they were able to use its accelerometer to recognize hand motions and, in some cases, bio-acoustic sounds associated with 25 different hand activities at around 95 percent accuracy. And those 25 activities are just the beginning of what might be possible to detect.
