Despite research having shown that signing users vary in their preferences and needs of distinct sign language (SL) parameters, current research on SL avatars lacks consideration of the UI context’s options for individualization or configuration of such parameters. Our paper addresses this gap as it presents our ability-oriented online survey, in which we asked native signers about parameters they would like to configure, as well content types that should be offered for translation within travel contexts. Our results indicate that parameters with a direct influence on the understandability of the avatar are most important for individual adjustments and situations with high time-pressure are valued highly for translation within travelling contexts. Also, our study design revealed that assessing the language background of participants in the form of an example-based self-assessment can help achieve more sensitive results, emphasizing the need for adequate research approaches.
