On April 2nd, according to the list recently published by the United States Patent and Trademark Office (USPTO), Microsoft has been granted a patent for a headset, which focuses on introducing a solution for "tongue gesture" interaction.
In the patent description, Microsoft envisions a system or application controlled using "tongue gestures," and even proposes typing on a virtual keyboard using "tongue gestures."
Microsoft suggests installing special sensors on the headgear, with one example being the installation of inertial sensors to receive one or more motion signals, thereby tracking and monitoring "tongue gestures."
After the sensors track and receive these "tongue gestures," their data is transmitted to a computing system (comprising at least one processor and a storage medium). The system then analyzes these motion signals and controls applications based on the tongue gestures. Here is a screenshot related to the patent:
