I would also venture to say that unlike a mobile phone, a wrist-worn connected device can hear pretty much what your ears can hear. In theory with better hardware it could hear even more. The point I am coming to in this article is that I want to propose the idea that by constantly listening to your surroundings, a smartwatch can fulfill a new and as of yet under-utilized purpose. That purpose is to use machine learning to allow software to recognize what a user is currently doing, all the while offering information or an experience that is relevant to that specific contextual situation. In very simple terms, a watch that hears you are outside (by listening to sounds it has learned) might display a particular watch dial better suited to being readable in a high-light environment. Conversely, while exiting a building at night into the outside, a watch dial might offer an automatically activating backlight in order to offer darkness visibility. This would be because the watch might recognize simple noises such as evening insects or less traffic as being an indicator that it is likely nighttime.
