Hello The Eye Tracking Researchers
I would like to design a study on some features of ADHD using eye tracking method in my lab (Dhaka University Memory Research Unit). I am seeking a suggestion regarding suitability of the eye tribe device to study in that area. Point to be noted, I am not expert utilizing eye tracking, you can say I am a beginner. My budget is pretty low and as a result I am planning to buy eyetribe ($99).
My question is will it be worthy to buy that device for conducting experiments as a beginner? Or what are the areas of research I can do with that device?
I would be happy if you provide any basic paper or book (with pdf download link) through I can be benefited.
Thanks
Asheek
Hi Asheek,
seems to be an interesting question for research.
As a possible starting point I suggest:
Dalmaijer, Edwin S. (2014): Is the low-cost EyeTribe eye tracker any good for research? DOI: 10.7287/PEERJ.PREPRINTS.585V1
Best,
Matthias.
Dear Asheek,
I recommend really thinking about "saving money" on the eye tracker. If you want to do purely scanpath based studies (just where people looking at), then a low-cost, low-sampling eye tracker will be fine. But if you want to do more thorough research on how people look (e.g. analyze saccades including their peak velocities) you need a higher sampling rate (250Hz+). In addition, you also pay for the software when buying a more expensive eye tracker, which is a large advantage for people with little programming skills or time.
On the other hand if you have a lot of time and very little money, EyeTribe might suffice - or you could even built you own (see papers).
Also have a look at the list in the Conclusion of Anderrsons paper (p.11; see link) where some considerations are given w.r.t to sampling rate and experiment design.
Greetings, David

who will be wearing the eye tracker? The therapist or the subject? It is important to know what you are measuring.
Dear Lode Goukens
Thanks for hour concern. Surely, the eye tracking device would be weared by participants. I want to know the nature of attention deficit in ADHD sufferers. I interested to develop a pre-screening marker on the basis of eye tracking. Hope you got your answer.

most persons with ADHD are excellent sportsmen. Especially in ball games. This might become very interesting.
