Fisheye zoom and semantic zoom on citation network visualization

Searching for a relevant paper is usually done in a tedious and an inefficient way by searching from written references. Another approach is to use citation network. A citation network is a visualization from summary of papers that show the connectivity between the papers according to certain parameters. This paper describes a new way to see the detail from available data. Our approach is a combination of fisheye zoom and semantic zoom. Fisheye zoom is used to mark the data that will be selected by the user, while the semantic zoom is used to drill down the data. The methods employed in this paper are designed by considering usability and user experience goals. Usability testing involving ten people is employed to evaluate whether the design goals are achieved or not. According to the evaluation, our design approaches have fulfilled usability goals of effectiveness, efficiency & learnability as well as user experience goals of aesthetically pleasing, fun, comfortable & helpful.
