I'm planning to use the diameter of an eye pupil in order to provide some parameters to adapt the Graphic User Interface according the diameter of the pupil.
Hi,
I think you can measure how tired someone is by looking at their eye. There was a researcher team here in Germany who created a device to measure how fatigued divers were on the rest spots of the autobahn. I am not sure if they had to stimulate their eye and look at their iris's reaction speed or measure the length of the blinks or a combination, but you can try to find out about their research to get you started.
Cheers,
Zoltan
In my opinion, pupil diameter can tell us about location of object in focus. Large diameter indicates that object of attention is far away while small diameter indicates that object of attention is near eye.
Peter, firstly, this work is on an initial stage, then, I'd like to detect any visual problem (physiological and/or pathological).
An example of data that I have is:
DiameterOfPupil[13,14,20,22,27,35,44,47,55,58];
Where is observed that the diameterOfPupil has increased significantly according to the time of observation.
Zoltan, I'll take a look on this project that you mentioned.
Thank you very much by the answer.
Some more facts:
1. You can use pupil diameter as a measurement for cognitive load (task difficulty).
2. Some folks use pupil diameter as a measurement for emotions while solving a task.
(But, first of all it would be better to think about a research question, then getting the design and after that the data.)
