Their overall opinion was that the link lens would affect their browsing strategies. With the exception of the document abstract, there was no consensus about which parts of the link lens would be the most useful, but all subjects expressed a desire to be able to choose a subset of meta-data for viewing at one time. Depending on the task being undertaken, the subjects felt that some parts of the link lens could be beneficial to the usability of the system.
We are currently carrying out further testing of several versions of the link lens with groups of Web users. The objectives include evaluating the value to users of the various different kinds of link information. We are also investigating different ways of presenting the information, including enabling users to customise or adapt the link lens to match their needs, and more economical encodings based upon the appearance of the link in the referencing document. A particular emphasis of this work will be to explore how degrees of user experience affect their ability to make use of link information.
