First Claim
Patent Images
1. A touch-based apparatus, comprising:
- a display screen for displaying images thereon;
a sensitive screen sensing touching inputs at a touched portion of the sensitive screen to produce electrical signals representing positional coordinates of the touched portion in response to the touching inputs; and
a micro processing unit coupled with the display screen and the sensitive screen, the micro processing unit calculating an area of the touched portion according to the electrical signals, and deriving a display ratio of the images corresponding to the calculated areas of the touched portion.

Abstract
A touch-based apparatus includes a display screen, a sensitive screen, and a micro processing unit. The sensitive screen and the display screen are coupled to the micro processing unit. The display screen is used for displaying images or icons. The sensitive screen is used for detecting positional coordinate of the touched portion. The micro processing unit is used for calculating an area of the touched portion according to the positional coordinate, and adjusting a display ratio of the images and icons based on the calculated areas.
