Implementing a natural user interface for camera phones using visual tags
Pointing is a natural way of communicating. Children in all cultures use pointing inherently. Attaching tags to our environment enables interaction by pointing. Visual tags are a good choice when low-cost and easy production are the issues. Adding visual markers to printed media adds a new dimension to it. A magazine can have direct links to web-pages related to the articles and ordering something from a catalogue is made straightforward. The use of the visual markers is reasonable in printed mass media as there is no additional cost. 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...
