There are technologies out there attempting to make capacitive screen/pen pressure sensitive but those pens are very expensive and it's not certain how well they work. as long as the application supports it, you can actually make a line thicker by writing harder on the screen just as with real paper and pen.

An active digitizer can send data of pressure sensitivity, i.e. Writing without resting palm on the screen for prolonged time is very uncomfortable.

So as soon as your palm rests on the screen, you lose writing. However, capacitive cannot distinguish between palm touch and pen touch as it only recognizes that something is touching the screen.

Just write things on your paper and you should quickly realize your natural writing behavior is to rest the palm on the paper. Since inductive technology recognizes the digitizer as a separate input device, if you rest your hand on the screen, it can ignore the palm. In fact, even regular handwriting size is probably too small for it to be well detected. On the opposite, a capacitive pen needs certain amount of contact surface, therefore you can not write too small. Similarly, a well implemented active digitizer will let you write as small as you can actually write. Try writing very small letters on actual paper with your pen/pencil. Wacom are actually screen recognizing pen itself as a special input device.Ī few major advantages of having an active digitizer, but in short capacitive can not give true paper & pen feeling, whereas an active digitizer can (potentially).Īccuracy. instead of using your finger, the pen tip has enough contact surface that mimics finger touch. Capacitive pen means nothing but finger replacement, i.e.
