Abstract
Recently, an interest in a mobile search is increasing according to the growing propagation of smart phones. However, a keypad, which is not appropriate for mobile environment, is the only input media for the mobile search. As an alternative, voice emerged as a new media for the mobile search, but this also has weaknesses. Thus, in the paper, we propose a mobile content called Orthros for searching the Internet using images as an input. Orthros extracts texts from images, and then inserts the texts to public search engines as a keyword. Also, Orthros can repeat searching with the extracted texts by storing result URL to internal databases. As an experiment, we analyze properties of recognizable images and present the implementation method in details.
