How the Computer Works Based on Pen

How the Computer Works Based on Pen.
Even the mouse is far from achieving the elimination of the keyboard, for sure the main barrier to computer use in various situations. This barrier is being attacked now by PCs with stylus.
The aim of this type of computer is to simulate a pad of paper and a pen common. With the width and height of a block paper, but generally thicker, such a computer can be supported with one hand while the other
write, draw or pick something on the flat screen LCD.

To achieve this simplicity, the computer needs to achieve two goals: to recognize the movements of the pen and translate movements in intelligible characters or functions. Operating systems-based computers recognize pen certain movements of the pen related to certain actions, such as drawing a circle or delete a word. Are
also capable of recognizing characters written with incredible accuracy, and must be trained to recognize characters written by the user, which are not always legible.

The pen-based computing is still in its infancy, and the processors found in them are not
powerful enough to convert, simply and quickly, writing in plain text. For this reason, the trend
applications for pen-based computers must prioritize model forms that can be filled
through dialog boxes and menus of options, such as forms, purchase orders and tickets
passages.

Even when processing performance and program reach a satisfactory level, the technology of this type of
computer remains very similar to what you will see in the next topics. We will examine the two ways of detecting movements of the pen and the way these PCs incorporate movements texts or actions.
