We propose a new technology called the Camera-TypingInterface, which can read printed characterssuch as URLs with a low-resolution camera. It realizesa type of ubiquitous information service using smartphones with cameras. This method includes two mainadvantages: automatic concatenation of sequentialshots and automatic error correction by re-shooting.The automatic concatenation enables a user to takesegmented images of a character string, thus a low-resolutioncamera can be used as the interface device.The automatic error correction enables the user tocorrect misrecognized characters just by retakingimages around them, providing an easy and naturalway of error correction. We present two experimentalresults to prove effectiveness of our method. Bothresults indicate that our proposed method is helpful.
