Apple Insider reported that Apple is working on a new mechanism to allow users to control Apple Watch smart watches or iPhone smart phones and other devices through "blow". On Thursday, the United States Patent and Trademark Office (USPTO) announced a new patent application outlining a new solution for "detecting hit events" and "switching between different modes of electronic devices."

Interestingly, the so-called "hit event" mentioned here actually refers to the user "blow" to the device to trigger different functions. Although it sounds strange, there are several use cases mentioned in the documentation.
Portable electronic devices usually require the user to hold with one hand and then physically interact with the device with the other hand to achieve user command input for specific functions.
But when the user cannot directly use physical contact to input interactive commands to the electronic device, the actual experience will be greatly reduced.

If the wearer of the Apple Watch smart watch cannot click on the dial because both hands are carrying the bag, the new scheme still allows them to trigger specific functions-such as answering calls.
detects changes in pressure and value through sensors to identify related "hit" events. However, in order to improve the recognition accuracy, sensor components such as a temperature and humidity meter can also be integrated. The

patent states that in addition to triggering a specific single "hit" event, the system can also map various commands to different events. In addition to wearable devices, the patent document also shows that this technology can be applied to iPhone smart phones.
It is worth mentioning that Apple has also tried other non-contact interaction methods before, including 3D aerial gestures for Mac and AirPods .As for when the new technology will officially arrive, it is currently unknown.
