A new customizable interface for smart devices based on hyperlink associability is presented. Although mobile devices should be easy to use, many current devices have complex and widely varying interfaces for users. The proposed architecture, Hyrax, attempts to improve the menu structure and accessibility of functions with consideration of user preferences. In Hyrax, the user interface is constructed and customized using hyperlinks for access to application functions. We focus on the user interface of a phone and present the customizable menu structure of the phone using XLink defined in W3C and External Function Interface (EFI) defined in the WAP Forum specifications.
