It is convenient not only for ordinary people but also for elderly and disabled people to have a real-world oriented interface that allows us to "click" real-world objects for obtaining their relevant information as well as to establish hyperlinks by taking their pictures. In this research, we have implemented such functionality based on a large-scale, high speed recognition/retrieval method which realizes real-time processing for databases of 1 million pictures, 55 small objects, several historical buildings in Kanto and Kansai areas, and 20,000 document pages.
