What's the eyeboard?
The Eyeboard is an open source eye-tracking project built with the intention to help people with disabilities.
People with physical disabilities face a lot of communication problems with other people.
This is why we were motivated to build an inexpensive, yet reliable, human-computer interface that detected eye movements using the technique used in the biomedical
field, Electrooculography (EOG).
How it works?
Electro- oculography (EOG) is a technology that consists of placing electrodes around the eyes on the person’s forehead to record eye movements.
The voltage that exists between the eyes is a very small electrical potential that can be detected using electrodes. People with certain disabilities may use these
systems in order to have certain communication. However, systems like these tend to be very expensive due to their complexity; therefore, this open source project
could be beneficial to a lot of people around the world.
Building the eyeboard
If you would like to know how the eyeboard circuit works, start by reading
this guide about the eyeboard's functionality.
If you are interested in building your own eyeboard, you can read the
MAKE Magazine article that explains the building process, and you can download the source code
The Eyeboard Kit
There is considerably enough documentation available so you can build the eyeboard on your own. However, if you would like to just go straight to the building phase
with all the necessary elements and a step-by-step tutorial (not the one in MAKE), we suggest you to take advantage of our experiential learning program and get the
eyeboard DIY kit from our store. The tutorial will guide you through the process, and will start from the basics to more advanced concepts
so you can build the eyeboard. You will learn concepts such as ADC, the use of filters and operational amplifiers, etc.
