Test
Hello and welcome from Hamburg, Germany!
Thank you so much for your interest in my survey. For the past two months I have been working on my Bachelor thesis about problems for people with color vision deficiency (color vision impairment, colorblindness) in street maps. Your participation helps me finally put my research and work to a real-life test.
The majority of questions is about identifying street classes in map images. The whole survey should take about 20 minutes.
If you do not have a color vision deficiency, this survey is not for you. Thanks for your interest though. :-)
If you are interested in the outcome of this survey or my thesis (german language, but I will probably write something about it in english) feel welcome to send me a message at johannes.kroeger@hcu-hamburg.de
This survey is hosted by myself, no data ends up in the hands of others unless you specifically allow me to share it (that is asked at the end of the survey).
Thanks, Hannes
There are 68 questions in this survey

If you do not have a color vision deficiency then this survey is not for you. So it is an early good-bye. :-)
Thank you for your interest and please share the link so color vision impaired people see and get the chance to participate.
All the best and thanks again, Hannes
Only answer this question if the following conditions are met:
° ((whatcvd.NAOK == "A9"))

Alright, let's go!
You will be presented quite a lot of questions but since they are hopefully simple, each should not take much longer than 15-20 seconds. Overall the test should not take much longer than 20 minutes, I aimed for 15 minutes. If it takes too long, blame my design, not yourself. You can skip all questions but of course that would make me rather sad.
You can pause and resume this test at any time.
If you usually wear glasses when working at the PC, please wear them now. Make yourself comfortable. The test should be in normal conditions (distance to screen, lighting etc). Apart from normal glasses, please do not use any vision-altering devices like lenses or smartphone apps.

May your answers be publically released?
Any personalised information (IP address, time, location, e-mail address etc) would be removed beforehand. Privacy is very important to me. Important enough to invest the extra time to host this survey on a webserver of my own so no one else gets your data.
I have no idea how successful this survey will be but I believe in open science. Allowing others to use data I collected seems like a good idea.
If you do not choose an option below, it will be considered a "No".
Please choose only one of the following:
-
Yes
-
No
Thank you so very much for completing this survey.
If you marked yourself interested in the results or later similar surveys, we'll be in touch.
In any case, have a fantastic day!
All the best, Hannes

Do you have a color-vision deficiency?
If you can or want, please feel welcome to further specify the kind of your color-vision deficiency in the comment box. If you have an additional different vision deficiency, please specify in the comment box.
If you know that you have a color vision deficiency but not what kind, you could try this hue arrangement test (link opens a new browser window) by colblindor.com. It just takes a few minutes (5-10). While this can not replace a proper examination by an eye specialist, it might give a good approximation. If you decide to take it, please copy the results into the comment field, it might help tremendously on the analysis. I took the test myself and found it quite fun, almost like a game.
