Power to be You

Our technology benefits those who use it and the people around them – parents, siblings, grandparents, caregivers, teachers and clinicians as well as others they encounter in everyday life. We empower people with complex communication and mobility needs to decide what to say and do on their own terms.

Solutions for a better life

We ensure that our technology and solutions for augmentative and alternative communication (AAC) are easy to use and can withstand daily stresses. Whether you need an assistive technology device, a communication app, eye gaze control of your computer, low tech materials or specialized training solutions, we strive to develop top quality, effective products.

Tobii Dynavox history

The roots of Tobii Dynavox lie in two assistive technology industry pioneers: Sweden-based Tobii Technology and U.S.-based DynaVox. In 2014, the companies merged to give a voice to people with disabilities worldwide.

The Tobii story

Founded in 2001, Tobii Technology began selling eye tracking technology for gaze analysis to provide insightson human viewing behavior in areas such as psychology, athletics, and market research. In the summer of 2003, the Tobii founders met Dr. Mick Donegan, an assistive technology specialist, during a technology demo. Dr. Donegan saw that beyond gaze analysis, eye tracking computers could also be used for gaze control to benefit people with conditions that cause profound physical and verbal limitations. Eager to help him explore the concept further, Tobii sent Dr. Donegan a simple demo application to evaluate the technology’s potential as a communication aid.  

That September, Dr. Donegan began working with Tobii programmer Kirk Ewing to create the interface for a gaze control system. Their effort resulted in the launch of the MyTobii D10, the first desktop eye gaze communication aid. A tablet version of the system, the MyTobii P10, soon followed. With the launch of its first eye gaze AAC system, the MyTobii P-Series, Tobii began to build an international presence and opened an office in the U.S. in 2004, Germany in 2007, and China and Japan the following year. North American expansion continued with the 2008 acquisition of Assistive Technology Inc., founded in 1983 by doctors at Boston Children’s Hospital who developed tools to help children with disabilities. 

The Dynavox story

In 1983, Gary Kiliany, a graduate student at Carnegie Mellon University volunteering at the Rehabilitation Institute of Pittsburgh, met a woman with cerebral palsy who couldn’t communicate verbally. With guidance from Professor Mark Friedman, Killiany created a device known as the EyeTyper that allowed the woman to compose and speak what she wanted to say. Killiany and Friedman teamed up with local businessman Tilden Bennett to form Sentient Systems Technology, Inc. They mass-produced and marketed three generations of the EyeTyper across the US, giving Americans with significant speech impairment the ability to communicate.

In 1991 they shipped the first DynaVox-branded products — AAC devices that featured touch screens with dynamic displays. Two years later, the company introduced word and grammar prediction, allowing faster message composition. This touch-controlled technology would become DynaVox’s signature product.

In 1998 Sunrise Medical and Sentient Systems merged to become DynaVox Systems Inc. At that time, the traditional consumer of AAC devices had evolved from school-age children with congenital physical conditions to include adult survivors of head injuries, strokes, and other accidents that left them without functional speech. DynaVox led a lobbying effort resulting in Medicare coverage for AAC devices, a milestone that would prove beneficial to thousands of people.

Throughout the 2000s, DynaVox continued to set new industry standards for portable AAC devices, including the launch of the EyeMax, a device that individuals could access through their eye movements.

Better together

Tobii Technology’s May 2014 acquisition of DynaVox merged two companies dedicated to raising the quality of life for people with communication and mobility challenges. By this time, Tobii had become well established as the leading provider of eye tracking solutions for communication and computer/environmental access for individuals with conditions such as ALS, Rett syndrome, spinal cord injury and cerebral palsy. Simultaneously, DynaVox was known as the premier source of AAC solutions for speech, language and learning challenges related to autism, aphasia, cerebral palsy and other neurological disorders.

The union of the two companies as Tobii Dynavox gave the new entity an even stronger geographic presence in existing and emerging markets around the globe.

Today Tobii Dynavox has offices in Stockholm, Pittsburgh, Norway, Germany, France, the UK, China, Japan, South Korea, and Taiwan. Through its nearly 500 employees and a global network of partners, the company reaches thousands of people, empowering them to more fully engage in life via technology.
