This paper is a nice small introduction to how legal information systems can be possibly made more usable, and to diverse populations when it comes to education and ability. Software Usability and Legal Informatics by Anna Ronkainen :: SSRN.
This paper examines software usability from two different perspectives within legal informatics. Firstly, the current state of legal regulation of usability of medical systems is explored briefly. Secondly, different levels of usability in legal information systems are examined through two examples of trademark databases based on a high-usability represented model (Onomatics Quick Search) and the more traditional implementation model (USPTO TESS) with poor usability.
