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.
