Abstract: The advent of mobile devices imposes great challenges for
user-friendly displays for effective browsing for Web contents. This paper
reports some initial findings in an empirical study that explores the problem
of finding a highly-efficient, user-friendly interface design method on small
display devices. We compare three models using our PDA interface simulator:
presentation optimization method, semantic conversion method, and zooming
method. A controlled experiment has been carried out to identify the pros and
cons of each method. The results show that of the three interface methods, the
zooming method is slightly better than the semantic conversion method, while
they both outperform the optimizing presentation method. The results provide a
useful guidance for future design of small display devices.
