Following Samsung’s use of the S Pen in its latest Galaxy S III smartphone, Microsoft is planning its next-generation stylus, according to a patent approved recently.
Besides touch sensors, Microsoft’s ePen will have a gyroscope, accelerometers and other sensors, said PCWorld.
For example, users of the ePen would be able to adjust the thickness of a line by virtually sharpening the digital pen with a twist, or turn it into an eraser using a different grip.
