Control your PC with your tongue using the Mouth Pad

The world of PC gaming, despite its massive reach, often overlooks a significant segment of the population. Beyond the financial barrier of high-end components and games, standard peripherals like keyboards and mice can present physical limitations for gamers with limited mobility. But a new wave of assistive technology is poised to redefine what’s possible, promising to bridge this gap through innovative body-coupled interfaces.

Enter Augmental, a company specializing in Skinware—body-coupled interfaces designed to let users control computers, communicate with AI, and interact with digital worlds without relying on their hands. Their latest groundbreaking project is the Mouth Pad, an ingenious device that allows users to command PCs, tablets, and phones using only their tongue.

The technology behind the Mouth Pad is remarkably clever. It looks like the top half of a retainer, encased in custom 3D printed dental resin, but beneath the surface are flexible circuits. Instead of traditional clicks, users register inputs by running their tongue over the trackpad covering the roof of their mouth. Right-clicks and other functions are achieved through subtle gestures like sucking or sipping, allowing for complex click and drag motions.

This isn’t a radical concept; mouth-operated pens have existed in assistive tech for some time. However, Augmental has brought this innovation into the realm of high-performance gaming. The Mouth Pad offers an entirely novel way to engage with digital environments, moving control beyond physical constraints and opening up new avenues for interaction.

The journey to this device began with founder Tomás Vega, who initially pursued a vision for a brain-machine interface. However, recognizing the immense potential of immediate solutions—the need for aid “yesterday”—he pivoted his focus to developing practical interfaces. In 2019, Vega built an early prototype, describing it as a “lollipop with a bunch of sensors”.

Since that time, Augmental has refined the design, collaborating with early access users, including popular streamers who have demonstrated incredible skill in using mouth-based controls. This iterative process ensures that the technology is not just futuristic, but genuinely functional for real-world applications.

While the promise of improved accessibility—extending control far beyond gaming—is immense, the path forward still requires overcoming practical hurdles. Currently, the Mouth Pad remains a premium device, costing $1,400, and it is not yet FDA approved, meaning insurance reimbursements are still on the horizon.

Despite the price tag, the potential impact of this technology extends far beyond the gaming sphere. As the industry continues to explore human-computer interaction, there is growing hope that devices like the Mouth Pad will become more affordable sooner rather than later, ushering in a new era of inclusive digital experiences.
