33.2. Usability GuidelinesBy looking at the KaZaA network, we surmised that abuses are occurring, and their frequency demonstrates that they are not isolated events. Based on a list of security guidelines provided by Whitten and Tygar,[6] we created a modified list of usability guidelines adapted for peer-to-peer file sharing applications that take into account the unique demands of continuously connected systems that distribute personal files.
We then conducted a cognitive walkthrough and user study, paying close attention to whether the interface was able to meet these guidelines and, if not, why users were confused. |
