Corten gives an overview of the MouthPad^s two main operating modes.
The MouthPad^ has two modalities for cursor control: tongue-tracking and head-tracking. In either mode, you can use the MouthPad^ like a mouse or trackpad, with the tongue-operated trackpad available for gestures such as left and right clicks, drag-and-drop, scroll, and more.
The MouthPad^ offers tongue-based cursor control via the touchpad in the center of the device. Simply move your tongue freely on the trackpad in the direction you would like the mouse to move — just like moving a finger on the trackpad of a laptop. When using tongue-tracking on the MouthPad^, note that you do not need to apply force or pressure when moving the tongue — only light contact is needed.

The MouthPad^ supports head-tracking in any orientation — even while the user is horizontal. Simply tilt your head in the direction you want to point, and use your tongue for click gestures.
“Ratcheting” in head-tracking mode
Moving across a big screen? Use the MouthPad^s ratcheting feature to easily cover greater distances by resetting your range of motion — much like the “ratchet” mechanism of a socket wrench. To ratchet while in head-tracking mode:
In both head-tracking and tongue-tracking modes, the tongue is used for gestural inputs such as clicks. Most gestures are the same in both modes, with just a few variations, noted below.
Press your tongue against the trackpad on the roof of your mouth. With the MouthPad^ app open, you will see the blue line go up as you apply pressure. (A click will happen once the blue line crosses the green line.)
A right click ******is achieved with a sharp suction. This is usually achieved with your mouth closed and your tongue off the touchpad. One helpful technique is to imagine you are sipping through a straw, but with your lips closed (almost like a kissing gesture).
