Cursor Control on the MouthPad^

Corten gives an overview of the MouthPad^s two main operating modes.

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.

• Tongue Cursor Control: In this mode, your tongue's movements on the MouthPad^ control the cursor and activate click gestures on the device.
• Head Cursor Control + Tongue Gestures: In this mode, you can use gentle head movements to move the cursor around the screen, keeping the tongue free for clicks and other gestures.

Tongue Cursor Control

The MouthPad^ offers tongue-based cursor control via an 8-way directional pad (D-pad). The mapping at the moment is:

In order to successfully control cursor movements with your tongue, you must position your tongue in the desired directional section on the touchpad. ******You do not need to apply force/pressure with the tongue when positioning it on the touchpad—only light contact is needed.

Head Cursor Control

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

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:

1. Lightly touch the trackpad with your tongue to pause head-tracking. (Avoid applying much pressure, which may trigger a Left-Click).
2. Move your head to reset the cursor’s reference point.
3. Release the tongue to continue moving from the new position.

Trackpad controls + gestures

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.

Left Click

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.)

Right Click

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).
