Dear Stefania, I have completed the survey, but unfortunately find it confusing. I have completed the survey valid for me personally (as a paraplegic), in which contrast, braille, etc. is unimportant. But of course this is important for other users. Further, symbols, language are more or less important in different situations which I feel is inadequately covered in the survey. i.e. pre-info, info at attendance, signage during attendance, etc.. I fear that your return will not offer what you seek. Please consider my criticism as constructive as I know that effective survey constructs are not easy.
