Evaluating interfaces is part of his daily work. He uses different sets of heuristics depending on the particular project (some times more than a single set), but the selection is always made based on his knowledge; he doesn't uses any tool to make that decision. For the final report he uses some templates he has refined during his career, but he doesn't use any specialized tool during the evaluation itself: he documents his findings in a spreadsheet.

He would like to use some tool to help selecting the heuristics for every situation, and also to document and report all the details of the issues as they are found (including the related guidelines).

Their purpose is to evaluate an interface to check whether it follows some common principles to make it accessible to users with disabilities. Besides those principles, the experts may use other tools that run automatically or semi-automatically.
