Conventional scrolling methods for small sized display in PDAs or mobile phones are difficult to use when frequent switching of scrolling and editing operations are required, for example, browsing and operating large sized WWW pages.In this paper, we have proposed a new user-interface method to provide seamless switching of scrolling / zooming mode and editing mode, based on a "Paperweight Metaphor". A sheet of paper that has been placed on a slippery table is difficult to draw on. Therefore, in order to write or draw something on the sheet of paper, a person must secure the paper with his/her palm to avoid the paper from moving. This will be a good metaphor to design switching operation of scroll and editing modes.We have made a prototype system by placing a touch sensor under a PDA screen where user's palm will be hit. We also have developed an application program to switch scrolling / editing mode by the sensor output and assessed our method.
