Usability of electronic communication aids in the light of daily use

L. Hoffmann, J.-O. Wülfing
Electronic communication aids (ECA) are daily used devices by people with specific needs. Daily used devices have to fulfil some standards like the ISO 9241 part 11. We deployed an online-survey and interviewed users of such ECAs in order to show how usable they are. As we can show, electronic communication aids have low usability values corresponding to the measurement of effectiveness, efficiency, and satisfaction. Optimisation has necessarily to be done, e.g. concerning voice output, weight, and handling.
