Designing choice experiments for visually impaired

[melvin]

Hello,

I'm asking whether anyone can point me to resources for (or has experience in) designing choice experiments for visually impaired people e.g., partially or completely blind. These would involve using voice prompts/sound etc.

I asked several colleagues, but none of us are familiar with such studies (although they may of course exist).

I guess reading out choice tasks could be done for each profile in each alternative ("column-wise"), or reading out the levels for each attribute across alternatives ("row-wise"). It may be difficult for respondents to remember all the levels, so it likely puts restrictions on how many alternatives and attributes you can consider in the choice experiment.
