Augmental Develops Mouth-Based Touchpad for People with Paralysis

Augmental, an MIT startup, is revolutionizing assistive technology with its innovative mouth-based touchpad, designed to help people with paralysis interact with computers using tongue, mouth, and head gestures. This groundbreaking technology offers new levels of independence and accessibility for individuals with severe physical impairments.

A New Era of Accessibility

Augmental’s first product, the MouthPad, is a significant advancement in assistive technology. This device allows users to control their computer, smartphone, or tablet through intuitive tongue and head movements. The MouthPad’s pressure-sensitive touchpad, positioned on the roof of the mouth, works in conjunction with motion sensors to translate gestures into cursor movements and clicks. This seamless integration of technology and human capability provides users with a new way to interact with their devices without the need for traditional input methods.

The creation of the MouthPad is a testament to the innovative spirit of Augmental’s co-founders, Tomás Vega and Corten Singer. Their journey began at the MIT Media Lab, where they were inspired to develop technology that could augment human abilities. Vega’s background in engineering and neuroscience, coupled with his personal experiences, fueled his passion for creating solutions that enhance accessibility and empower users.

The Technology Behind the MouthPad

The MouthPad uses a 3D model based on a scan of the user’s mouth to generate a customized retainer. This retainer, made from dental-grade materials, houses the electronic components. Users can perform various functions by sliding their tongue to scroll, using sipping gestures to right-click, and pressing their palate to left-click. For those with limited tongue control, the device can also recognize bites, clenches, and other gestures, while head-tracking technology allows users with more neck control to move the cursor on their screen.

The versatility of the MouthPad makes it suitable for a wide range of users, including those with spinal cord injuries, quadriplegia, and other conditions that limit hand or arm movement. The device has been particularly beneficial for gamers, programmers, and students, enabling them to engage with their devices for extended periods—some for up to nine hours a day.

Scaling and Future Developments

Augmental is focused on scaling its operations and improving the MouthPad’s capabilities. The company is seeking U.S. Food and Drug Administration (FDA) clearance, which will not only validate the device’s safety and effectiveness but also enable insurance reimbursements, making the technology more accessible to a broader audience. The FDA clearance will also pave the way for the MouthPad to be used in controlling wheelchairs and robotic arms, further enhancing its utility.

Innovation at Augmental doesn’t stop with the current version of the MouthPad. The team is working on a next-generation model that will respond to even more subtle movements, such as whispers and internal speech organ gestures. This development is crucial for users with impaired lung function, as it offers a more nuanced and responsive interface.

Real-World Impact

The impact of the MouthPad on users’ lives is profound. One user, who is living with quadriplegia, has been able to take notes in class, play games, and engage in social activities more independently. Such stories highlight the transformative potential of Augmental’s technology. The startup’s goal is to ensure that individuals with severe hand impairments can use phones and tablets as efficiently as those using their hands.

Augmental’s vision extends beyond just creating assistive devices; they aim to develop an always-available, robust, and private interface to intelligence. As advancements in AI and wearable technology continue, Augmental is positioned to lead the way in providing accessible and innovative solutions for people with disabilities.
