If it determines you smell unpleasant and you’re on your way, the device will use social networks to locate friends and suggest a different route. It also emmits deodorant so that your sweat is at least covered a bit.
“The route suggesting portion may provide an alternate route to travel such that the predicted odor may not offend others that are socially connected to the user and that travel the same routes as the user”, Google writes in the patent proposal. To determine whether you smell bad the device uses various sensors to measure e.g. your body temperature and heart rate. These indicators assist in determining the perspiration level. In other words: how much and how bad you sweat.
But will this wearable odour-neutraliser mean that Google has another platform to have our every movement tracked???
