What we do

Our aim is to bring easy access of visual STEM (Science, Technology, Engineering and Mathematics) data to blind and visually impaired Students. We believe that scientific data of all forms should be accessible to anyone.

Grapheel’s projects are born of the desire to help open the doors to STEM to everyone, and as such we are keen to welcome new ideas and volunteers from around the world.

Why we do it

Founded by a small team of scientists from the University of Sussex and headed up by a blind theoretical physicist, Grapheel knows the challenges faced by STEM students, let alone those who don’t have access to all available resources.

Our founder, Daniel Hajas, wants to harness his unique perspective and enable students like him to pursue their passion for STEM and open doors to future opportunities.

We are developing a web app, available across all online platforms, making use of a network of researchers, programmers and other scientifically minded people who are passionate about making sure nobody gets left in the dark.

Consultancy and training

We know how difficult it is to find support when it comes to making scientific learning and teaching content accessible. In addition to our other services, we wish to offer practical help with tackling science classes with ease.

MIDAS – A Golden Touch

Grapheel’s MIDAS project focuses on developing technologies to support a new class of device, tactile displays. This involves both hardware and software research, including the creation of an app store for tactile displays.  We’re also working on providing new technologies

What our Community Says

I do enjoy IRIS, of course it satisfies the human desire to feel helpful which makes me very happy to help others but I also like that it forces me to stop and think about what I am seeing. This both gives me a kind of mindfulness feeling but also helps me practice giving attention to small details, and I hope in time this will make me into some kind of super skilled graph expert.
