Usable Persona Interface: Persona-Bookmark

We present a design that assigns persona information and uses it to selects one identity from several user identities in user resources such as bookmarks. As a proof of concept, we implemented a persona-bookmark system. In this system, a user can assign his persona information to his bookmarks so that the system automates login processes using the persona information. Thus, the user can log into a service just by selecting its bookmark. We estimated the operation time for logging into services by using the GOMS-KLM model. The results indicate the usefulness of our model and its implementation.
