Abstract
Reader feedback is generally considered to be valuable input for writers who want to optimize their documents, but a reader-focused evaluation is often time-consuming. For this reason, we have developed Focus, a software tool for collecting reader comments more efficiently. The design and rationale of the software are described in this article. In a small-scale evaluation study, the results we obtained using Focus were compared to the reader feedback collected under the plus-minus method. It appeared that the number of problems detected per participant did not differ, but there were differences in the types of problems found. Focus participants appeared to comment more from a reviewer's and less from a user's perspective. Although the two methods are not interchangeable, Focus can be said to be a promising evaluation tool, deserving further research.
