Tangible search system using RFID technology

Many types of information input methods into computers have been invented and used from keyboard and mouse to touch-panel display. However, each operation method is totally different and it often takes much time to learn how to operate it. For example, when customers use an information terminal at a retail store, they may have to browse more than a few pages or type several appropriate words with a keyboard or something to get to the information they want. It is very laborious and complicated especially for inexperienced users. Therefore, more intuitive and simple user interface has been desired for a long time.
