The design of ViVA: a mixed-initiative visual vocabulary for aphasia

The visual vocabulary for aphasia implements a novel approach that organizes the words in the vocabulary according to user preferences, word usage and certain semantic measures, thus continuously tailoring the tool to the user's profile.
