This paper summarises some of the findings from a preliminary survey conducted to evaluate the comprehension of pictographs for patient responses in the speech-to-speech translation tool BabelDr, a system designed to improve communication between doctors and allophone patients or minority groups. Despite the relatively low number of respondents, the gathered data could serve as a starting point for discussion in future decision-making processes about how to design a bidirectional interface for patients with a range of pictographs and how to evaluate their comprehension.
