More and more trustful reports seem to suggest that Apple is indeed working on the iPad Pro, and even the company's own patents seem to show it. It's not the first time when we're seeing this, but a fresh stylus concept was revealed in Apple's filing for "Expanded Function Touch Sensor Implement," published this week by the U.S. Patent and Trademark Office,
The invention describes an advanced stylus with a number of sensors to detect a variety of types of input, such as the angle at which the stylus is touching the display, or the distance of the stylus from the device. Of course, at the moment we're not sure if such a tool would be limited to the iPad Pro, but it would definitely make work easier on the device, if it does come with a screen size bigger than 12-inch.
The advanced stylus could allow for 3D input thanks to the many sensors that it comes packing. The “grip sensor” would sense the amount of force with which the user is gripping while the pressure sensor would measure how hard the user is pressing the stylus against the device.
Also, along with a built-in gyroscope or accelerometer, the stylus could allow for new features like 3D handwriting. But it could also be equipped with hardware buttons for alternative input methods.
It needs to be pointed out that there are already several pens available on the market for iPad devices, but of course, none of them could be as popular as the one on which Apple is allegedly working.
