adaptive processor

Adapro is an open-source, multi-platform and multi-user text processor especifically aimed at people with learning difficulties such as dyslexia or other developmental disorder (i.e. autism). Its adapted, seamless and configurable interface provides a simplified environment that can be relied, fostering the user’s sustained attention. It’s available in English, Spanish and Portuguese.

The “design thinking” process was critical to study the current market and understand the needs of users with learning disabilities.

Several funtional communication tools were analyzed, and applying etnographic observation helped in understanding both their strenghts and weaknesses from the users’ perspective.

This enabled us to establish a clear goal in order to design and develop an adaptable, seamless, lightweight, portable and configurable pictogram based word processor, carefully designed to meet the particular needs of these type of users.

During the first phase of our research, the following main insights were discovered:

  • Current adapted word processors do not offer a user-friendly document management system.
  • Users with dyslexia frequently mix up the letters “pbdq” due to their typographic similarities.
  • It is essential to provide users with other text input methods to speed up their interaction with the processor.
  • Picto-word processors don’t allow the file to be exported to a fully editable format.
High-contrast modes

Adapro allows the user to shift between different background colour schemes in the document area to enhance visual aid. The user can choose between the traditional white, yellow or black.

10,000+ pictograms

In-line representation of words through graphic symbols is possible as the suite includes more than 10,000 pictograms provided by the ARASAAC catalogue.

Virtual keypads

Adapro incorporates virtual keypads; a simulation of keys with pre-defined phrases. A separate keypad editing tool is also included.

Sarakanda, an accessible typeface

Created in 2008 by Alejandro Valdez Sanabria, the typeface was especially designed for children with dyslexia. Its stems, serifs, ascenders and descenders enable a clearer legibility due to the contrasting patterns perceived in different word formations (silent reading).


Highlighting of the letters p, b, d and q to allow more contrast between them and provide further reading assistance to dyslexics.

Friendly document management and RTF export

The file system is seamless, avoiding any file management through the operating system and assisting the user in quick document searching in the application itself. Quick view is available to examine the content of the document before opening it. Any content can be exported to RTF format, allowing the user to continue with their work using any other word processor such as Microsoft Word, Pages or OpenOffice.

Adapro makes their life easier

Many users have shared their experience with the platform on the Internet. An example is a video uploaded on YouTube by Galician school Escola de Casalonga in Teo, A Coruña, Spain, where Adapro is implemented in classes to aid students with special needs.
