Introduction to RoboBraille

RoboBraille is an e-mail and web-based service capable of automatically transforming documents into a variety of alternate formats for the visually and reading impaired.

RoboBraille is accessible 24/7 as a self-service solution and is available free of charge to individual, non-commercial user not affiliated with an institutional setting obligated to provide support (academic institution, organisation, association or similar). Users need not register in order to use the service. The objective is to support and promote self-sufficiency of people with special needs socially, throughout the educational system and on the labour market. As an additional benefit, RoboBraille helps to protect the privacy of of those who need material in alternate formats.

For institutional use (including academic institution, organisation, association or similar), the RoboBraille web interface is available in customised versions to academic institutions and other organisations that wish to include it on their websites as an accommodation. The document conversion capabilities of RoboBraille can also be integrated with library systems and learning management systems in order to support users with special needs. Institutional use is subject to a subscription fee. Please contact Sensus at or +45 48 22 10 03 to obtain a service agreement to use RoboBraille for academic and/or institutional purposes.

RoboBraille was originally created by Synscenter Refsnæs (the National Centre for Visually Impaired Children and Youth in Denmark) and Sensus ApS. Today, the service is developed and operated by Sensus and RoboBraille Outreach, a non-profit association. Since its launch in 2004, RoboBraille has received numerous international awards including the WISE 2012 Award for Inclusion in Education, the BETT 2010 Award for Best Special Education Needs solution and the 2008 European Commission e-Inclusion Award for e-Accessibility.

RoboBraille is part of the Raising the Floor Initiative to improve accessibility and further inclusion. RoboBraille is also a friend of the DAISY Consortium, implementing several parts of the DAISY Pipeline into RoboBraille. RoboBraille wishes to thank the DAISY Consortium for providing access to its open source projects. RoboBraille also wishes to thank Microsoft for donating Microsoft Office-licenses to the service.
