Mobile devices are quickly becoming powerful devices enough to run personal computers. However to control large visual information is still the critical issue for them. This paper introduces several zooming tools such as a focus zoom, a file zoom and a search zoom which are based on geometric and semantic zooming methods as new viewing methods. These zooming tools are developed to devise an efficient method for handling the viewing issue, displaying large visual information on a small size screen. In addition, the paper introduces usability testing method on mobile devices to find hidden issues in the tool, and mentions further progress to improve the usability of working on devices.
