Apple has patented technology for stylus pen at the Office of Patents and Trademarks United States, most likely, intelligent stylus that Apple will be named iPen.
Unlike the stylus in general, Apple stylus works can be called intelligent because it can give feedback. Stylus can feel the vibration, how much pressure a user when drawing, when the pressure of the stylus is rather strong, so he can draw a thicker line.
Uniquely, the digital pen can also give voice to stimulate the action of the user. Stylus will give voice that was a pencil drawing on paper, or brush that are painting on canvas. In his patent files, Apple also promised a stylus can be used in the air, without having direct contact with the screen.
All functions can be done because of Apple's technology utilizes accelerometers, gyroscopes, and a camera embedded in the stylus. And currently, there is some stylus for iPad made by third parties. However, none of the stylus which has the same functions as that patented by Apple.
This stylus patent marks a change in Apple's strategy in the business of mobile devices. Because, the late Steve Jobs had mocked the stylus in 2007 ago is widely used as an accessory. "Who wants a stylus? You have to get it, save it, and eliminate them," complained Steve Jobs.
