During Europe’s biggest exhibition for assistive technologies for blind and visually impaired people, Inventivio introduced the latest prototype of the Tactonom. We thank the many visitors for their interest and their many enouraging comments. For us your support is a huge motivation to finalize the Tactonom and bring it into the hands of blind peole as soon as possible!

How the Tactonom works

The Tactonom translates the screen content and displays these via tactile points. The DIN A4 sized touch pad contains more than 10.500 tactile points which can display graphics and up to 22 rows of text.

The integrated camera can scan printed documents, convert these and display them on the Tactonom.

The finger recognition coupled with the voice out function simplifies the understanding of digital content.

With the zoom- und scroll functions the user can get an overview, zoom into details or scroll in all directions.

We provide an open software platform for the Tactonom which enables independent developers to bring their applications onto the tactile display. We will provide a free and open Software Development Kit for developers.
