A purpose-built speech generating device controlled with your eyes to communicate and access Windows.

Unlock possibilities

TD I-Series is an eye gaze-enabled speech generating device featuring the world’s leading eye tracker. Purpose-built for people with conditions such as cerebral palsy, Rett syndrome or ALS, this Windows-based device is controlled completely with your eyes to communicate and live more independently.

Multiple Access Methods

Outdoor Eye Tracking

Powerful Speakers

Partner Window

Assistive communication

The TD I-13 and TD I-16 are custom-built AAC devices that enable communication and independence for people with disabilities via eye control and other access methods.

Built for AAC

TD I-Series is a light, fast and durable speech generating device purpose-built for augmentative and alternative communication. It can be controlled via eye tracking in all kinds of lighting conditions, even outdoors. TD I-Series comes pre-loaded with AAC software to meet a range of communication needs, and projects your voice loud and clear thanks to powerful speakers. The device also offers a rear-facing Partner Window™ for more natural face-to-face conversations.

Built for independence

TD I-Series encourages independence, offering the ability to control your own doors, lights and phone, to turn your device on and off using Wake On Gaze™, and to customize key functions – all with your own eyes, fingers or with a switch. Feel confident using the water resistant and anti-glare TD I-Series wherever you go – even by water in bright sunshine.

Built for eye control

Tobii Dynavox’s newest eye tracker is based on 15+ years of research and testing across all types of ethnicities, disabilities, eyewear and lighting conditions, both indoors and outdoors. It offers precise eye gaze selection to quickly select screen targets, and the fastest recovery time if your eyes move outside of the tracking box.
