The EyeWriter is a low-cost eye-tracking apparatus + custom software that allows graffiti writers and artists with paralysis resulting from Amyotrophic Lateral Sclerosis to draw using only their eyes.

The original design, as shown here, featured a pair of glasses as the basis for the eyewriter design:


Since that first video, we've been hacking on and developing the project, and we have a new design, which we've called "eyewriter 2.0" which improves the accuracy of the device, and allow for people who's heads are moving slightly to also use an eye tracker. The original eyewriter, designed for a paralyzed Graffiti artist TEMPT1, is designed to be worn on a completely motionless head. The 2.0 design, which uses a camera and LED system mounted away from the head, can be used by people whose heads are moving slightly, such as MS patients, and people who wear glasses, etc.


This eyewriter system is cheap, and completely open source.  At the moment, it costs about 200$ in parts.  Traditional commercial eye trackers costs between $9000-$20,000, so this is a magnitude of order cheaper, and is designed to help anyone who wants or needs an eyetracker.

This fall, we've been showing off and demoing the 2.0 device -- check out the eyewriter 2.0 in action --  we even hooked it up to a robotic arm, to draw the artwork people make with their eyes:

(The 2.0 device was designed with help and input from Takayuki Ito, Kyle McDonald, Golan Levin and students of the eyewriter collab at Parsons MFADT.  Thanks also to the Studio for Creative Inquiry / CMU for hosting a session for development)

MOSFET - IRL3714ZPBF is obsoleted and no more available for buying.

can any one point me alternative MOSFET can be used here.

also asked on the circuit forum : http://forum.allaboutcircuits.com/threads/alternat...

There are two other things I would like to know:

1- does the EyeWriter work with an external display connected to a macbook pro?

2- does the EyeWriter software work with any higher OS X than Snow Leopard? Mountain Lion or Lion?

thanx a lot!!!

hi everybody,

I have a question about step 9 - getting the v-sync off the camera and LED flashing

- I build the circuit for the test

- Arduino is connected via USB

- I load StrobeEye.pde

- PSEye (v8.2) is connected via USB

- I start the macam driver

Before even the VSync contacts the thin wire the red LED flashs rapidly and continuously.

Is this the way it should be? If not what have I done wrong?

thanx

hi ^^
i have the same problem , i want to ask you if you solved the problem ???
I found out that in my case as decriped above:
- the red LED flashs rapidly and continuously as soon as I build the cicuit for the test.
- but as soon as I connect the VSync with the thin wire the flashing rhythm changes and is little slower.
Thats how I could find out that I have the right VSync point...

I can't remember exactly from my build but maybe that's the default
flash rate in the arduino sketch. The Vsync synchronizes the led
flashing rate of the arduino with the frame rate of the camera.

please tell me if some one has made this project on win plateform as i am trying to make this project for past few months but not even suucceded to compile code in code block..

Ben Mattinson made an excellent Windows
version of the software called EyewriterB that you just download from
GitHub and install like any windows program - no compiling.

and click "Raw" or "view full file"

Are there any specific webcams that won't work for this?

SimonV12 months ago

Hi, i have also struggled to build and run this. Do you think it would be possible to put this software into a downloadable app that could plug-and-play with an infrared USB webcam? Long shot but it would be brilliant if so. You could get this technology to so many people that way.

I need help compiling the RemoteEyeTracker Program. Any suggestion? I am using OS X Yosemite. Thanks

hey can we use a web cam for this and can we control a servo
of 9 g using our eye movements using arduino pls give me answer fast and it
would be nice of you to provide me with the codes and if web cam can be used
then how

yes there are some web cam available in market with ir capabilities you can use it.. but you have to work from scratch to control the servo .......

But can u tell me what variation in the codes i have to do if i want to control it with my arduino UNO

i have a question regarding hardware of eye writer ...... i follow each and every step .. vsyn works fine but when i turn on the entire circuit leds would not fleshes instead they stay on.. when i cut off supply of vsyn, leds start flashing any help regarding to this problem will be appreciated thanks
