Schematic diagram of Tecla Access user case

Tecla Access is a collection of mobile open source and open hardware applications that may be used to enable access to, and extend the functionality of, mobile devices for people with motor impairments.

Our initial goal is to enable access to mobile devices through the same interfaces that powered-wheelchair users employ to move around, thus allowing them to easily select between controlling their wheelchair or accessing their mobile device. The resulting tools and designs will also likely benefit other users with mild to severe motor impairments.

Tecla Access is part of the AEGIS (Ontario) Project. It is funded and supported by the Ontario Ministry of Research and Innovation and the AEGIS (Europe) Project.
