Augmental has officially opened public US sales for its innovative MouthPad, successfully transitioning its highly anticipated 2024 prototype into a fully available commercial product. The $1,400 device takes the form of a custom-fitted dental retainer that functions as a fully wireless, tongue-controlled computer mouse. While it represents a major leap in wearable technology, the device is designed primarily to empower individuals with severe mobility challenges, offering them unprecedented digital autonomy.

A Retainer That Functions as a Mouse

The MouthPad is engineered to fit securely over the upper teeth, closely resembling a standard slim orthodontic retainer. A highly sensitive, pressure-responsive trackpad rests flush against the roof of the user's mouth, allowing them to smoothly control a digital cursor, execute clicks, and perform complex swipe gestures using only their tongue.

To complement these tongue-driven commands, the system also integrates advanced head tracking for added movement control. All of these inputs and gestures are completely customizable, allowing individuals to tailor the experience through a dedicated companion app.

To acquire the specialized device, prospective users must first undergo a required 3D dental scan. This preliminary step costs approximately $100 on top of the base price and ensures a perfect, comfortable fit for everyday wear.

Unlike invasive surgical brain-computer interfaces, the MouthPad completely skips the operating room while still aiming to match their high level of precision. Augmental reports that a recent user successfully achieved a cursor accuracy of 10.47 bits per second during testing, an impressive benchmark used by the company to prove the hardware's viability for complex daily computing tasks.

The currently available second-generation model includes several specific upgrades over the original prototype:

• Extended battery life: The device now supports over seven hours of continuous use on a single charge.
• Multi-device connectivity: Users can pair the retainer via Bluetooth with multiple gadgets simultaneously, seamlessly switching between devices.
• Gaming support: Features a WASD remap mode designed for players looking for alternatives to standard PC hardware setups.
• Keyboard shortcuts: Supports complex, tongue-triggered command combinations to streamline digital workflows.

Vox: Translating Whispers into Keystrokes

Alongside the commercial launch of the MouthPad, Augmental introduced a beta release of Vox, a $200 wearable pendant. This complementary device is designed to handle the typing half of the hands-free computing experience, effectively acting as a wearable keyboard.

Vox is worn so that it sits directly against the skin on the user's throat. Instead of relying on traditional microphones, it reads speech through subtle body vibrations rather than picking up sound from the open air.

Borrowing key design principles from a medical stethoscope, the pendant effectively filters out disruptive background noise in busy environments. This allows the hardware to pick up accurate dictation even when the user speaks at a near whisper.

This deliberate activation method also serves as a strict privacy feature, firmly distinguishing Vox from always-listening smart speakers that passively record audio. The device is scheduled to ship in beta later this year, with Augmental directing proceeds from its first batch toward funding MouthPads for users who cannot afford the base price.

The Path to Silent Speech

Augmental notes that over 100 people with varying mobility challenges already rely on the MouthPad for their daily computing needs. The comfort of the custom-fit resin allows some early adopters to wear the device for up to 16 hours a day without experiencing severe fatigue.

In the long term, the company has highly ambitious plans for its hardware ecosystem. Augmental intends to combine the unique acoustic data gathered from the Vox pendant with the physical tongue-movement patterns recorded by the MouthPad's trackpad.

This deep integration aims to establish a reliable "silent speech" system. Ultimately, this technology could allow users to communicate entirely with their devices, writing emails and navigating software without making any audible sound whatsoever.
