- 2. Introduction There were 40.04 million users accessing the mobile Internet at least once a month and number increased by 33% over a period of year.

- 14. Conclusion The mobile Web poses several unique challenges to usability researchers and designers. These challenges are compounded by the mobile Web environment being only a part of the Web universe. What may be most needed in mobile/Web usability is a standardization of the usability process so comparisons can be easily made between devices and systems.
