MediaLab Eyetracker Slide Numbering

[JEC]

Chris,

Can you send me a link for documentation re: your eye tracker? Specifically, I'd like to see how it handles digital input.

Converting to binary is easy. If you're on a Windows machine, find the calculator. It's usually in the start menu, then under accessories.

When the program comes up, just type your decimal number in to the main window. Then, in the top left corner check 'Bin' instead of 'Dec.' The calculator will make the conversion for you.

You may need to prepend some zeroes to the answer you receive.

Example:

Decimal 32 is

100000 binary

You need it to be 8 digits long. So...

00100000

Make sense?

I would probably put this 'nametag' immediately following the trigger output you have in your MediaLab experiment, but before the stimulus is presented.

As far as placement goes...

My syntax is wrong, but the gist of it is:

--- Trigger EyeTracker
--- Send binary nametag
--- Display photo / video clip / etc

--- Repeat as required.
