Large interactive wall displays for multi-user interaction are readily available today. However, little is known about the specific aspects influencing usability for applications supporting several users interacting simultaneously and co-located with wall displays. Especially for large screen information applications in public or semi-public places, the ease of notic- ing and reading text is very important. In this study we are focusing on determining readability in corresponding single- user and multi-user scenarios. Participants in our laboratory study are presented with four different text moving directions in different settings. The evaluation of the results shows that the typical text moving direction (right to left) is not always the optimal choice. When just one user is standing in front of the screen our results showed a preference for a vertical text movement. For reading while walking we found it to be optimal if the text moves with the reader.    «
