How many times has this happened to us? We leave charged with the purchase of the supermarket, a bag in each hand, and they call us by phone. Luckily we wear our Apple Watch, but how do we respond? Can we with the hand? Do we hug our noses without anyone seeing us? Apple has patented a system that just might put an end to these fun, albeit uncomfortable, situations.

An original idea, yes, but practical

In the patent titled “Knock and Mode Change Event Detection with an Electronic Device”, Apple explores how to use artificial intelligence to detect the sound of our watch’s breath to perform certain actions. The truth is, the nature of the patent might even make us smile at the idea, but technically it’s a lot more complex than it looks.

The Apple Watch should be able to distinguish our intentional blow from the gusts of wind that occur when we are biking, running, or simply walking in windy weather. The model should also be trained so as not to confuse the friction of a sleeve of our clothes with other noises.

Part of the system to achieve this would be to further internalize the microphone and sensor into the watch case. This, combined with the possible use of a pressure sensor, would allow us to gauge when we are consciously blowing the clock. Motion sensors would also come into play, to be able to eliminate situations in which it is due to movement that an air flow occurs around the watch.

A fun idea, but much more practical than it seems at first glance.

Once we were able to detect our blowing, the truth is that there could be many applications for this system. The most obvious is to interact with our Apple Watch when our hands are full, whether it is to answer a call or to silence it, for example. But the patent goes much further and proposes a complete system of interaction by air; something similar to what we saw in the last Apple Watch accessibility update, which we can now only use by moving the fingers of the hand in which we wear it.

It is not known when or if this patent will take shape in a future Apple Watch. What we can clearly see is that in the Cupertino laboratories they come up with some pretty extravagant ideas. A lot of them must be lost along the way, sort of like “there are a thousand no’s for every yes”, but some, as crazy as they may seem, can end up being part of the products we use in our. everyday life.

At the end of the year, there are many patents that Apple files with the corresponding office in the United States. Many of these patents do not apply to products, but it is also true that various ideas that we have seen in the patents have served as the basis for the development of systems that we now take for granted. Something as simple as the inertial scroll, without going any further, the Apple Watch’s electrocardiogram or the detection of oxygen in the blood have proven their worth at one point.
