A conventional keypad user interface of mobile phones is unsuitable for some modern situations. Here we present a visual tagging system and show how such a system can be used for fast and efficient user interface, utilizing a camera phone as a pointing device. We also present our two optional mobile phone implementations, one aiming for very fast processing and the other for high detection resolution. These efficient implementations are achieved by taking into account the strict constraints of the mobile environment. We present a flexible system where varying physical and storage sizes of the visual tag can be used in different applications through one interface application and we present some performance statistics of our implementations. We also identify some of the constraints on the mobile device programming environment concentrating on Symbian Series 60 mobile phones.
