This paper presents u-Photo Mobile a clickable digital still image to visualize and operate ubiquitous services. U-Photo Mobile is designed and implemented to be executed on smart phones e.g. Apple's iPhone. Users shoot the ubiquitous services attached with a two-dimensional bar-code. The u-Photo Mobile system decodes the ID and finds functions of the service. The touch screen of u-Photo Mobile lets users check and control the service. The operation of ubiquitous services are realized by making a network connection between u-Photo Mobile and the services. With this intuitive method, the users can interact with ubiquitous service through the metaphor of “taking and tapping a photograph.” The u-Photo provides users with an instinctive technique, which realizes a seamless interaction between user's mobile phones and intelligent environments.
