Eyelink 1000 (scattered around the department)

Shih-Yu has used pylink code in his visionegg program to successfully talk to the eyetracker.

The same code should be used in psychopy, which we haven't done yet, but others have and there is a heap of information here: http://groups.google.com/group/psychopy-users/browse_thread/thread/4eaa80283f5a7030

CRS prototype Eye Tracker

This eye tracker is set up in Testing Booth 524B. It is connected to an Imac which is remotely accessible from any computer connected to the Psychology department's local area network. This means that after setting up your experiment as you usually would, and starting the subject on the experiment, you can return to your own computer, turn on the eye tracker and set it to record / run the software even as they are doing the task.

To do this:

  1. Open a "Finder" window on your own machine.
  2. Under "Shared" in the menu on the left (you may have to click on the triangle to expand the list and/or click on "All..." to see the full list of computers on the network), find the computer called "Holcombelab-eyetracker". This is the Imac that the eye tracker is connected to.
  3. Double click on it. This will connect you to the Imac as "Guest". Note that you only have access to "Public" folders on the eye tracker's Imac as a guest.
  4. In the top right hand corner of the finder window you can select to "Share Screen..."** if you want to control the computer connected to the eye tracker. This will give you remote access to the Imac's desktop environment in a window. Thus you'll be able to turn the eye tracker on or set it to record etc.
  5. If you want to transfer files or data onto your own computer from the eye tracker's Imac, Click on "Connect As..."** and some more folders will appear in the finder window. You can drag and drop files from these folders onto any folders on your own computer to transfer them across the network.
**To access these functions, you will need to log in. The user name is HolcombeLab (note 
the capitalisation), and the password is the common lab password (ask either me or Alex if you 
don't know what it is).

Currently (02/11/2010), we're still waiting on the software which will allow us to program the eye tracker, record from it, and collect data from it. But once we have it I'll update this page with the extra information. If you want to have a play with it right now (I.e. just try out screen sharing and start up the eye tracker), just share screens with "Holcombelab-eyetracker" and use the program "PiP" which you'll find to the right of the "Photobooth" icon on the dock bar.

Note. It's best if you don't start the eyetracker using the Imac in the lab as you then have to deal with the light emitted by it's screen (it will take about a minute to go back to sleep). If you access it remotely, the screen will stay asleep maintaining the dark in the testing booth.
