A partial zoom-in method for presbyopic people is proposed. The area of a user's attention is zoomed in to read clearly, and the magnification rate of the area around it is gradually reduced to zoom-out rate so that all information is displayed in the small display. Our idea is applied to an actual document containing text and image, i.e. a PDF file and a web page, and our method is implemented on a tablet PC to develop an experimental system. Presbyopic people tried it to see how it works, and they evaluated it positively.
