An Ink and Voice Annotation System for DENIM

I have implemented ink and voice annotations in DENIM, a sketch-based web site design and prototyping tool. I also performed an informal evaluation of the annotation feature with four participants, one of whom was a professional web designer. The evaluation focused on how people use ink and audio annotations to review existing designs of web sites. The participants in the experiment tended to use many more words in voice annotations than ink, and they used a more conversational tone with voice than with ink, which were usually short sentence fragments. Out of the four participants, one preferred ink, one preferred voice, and two had no preference for these specific tasks, although all four perceived a need for both types.
