We tested the Surface Pen in Microsoft’s preinstalled FreshPaint app and found the amount of pressure needed to draw a satisfyingly dark line was ridiculous. In practice, this technology is a bit iffy, though. Microsoft boasts that its pen can experience 256 different levels of pressure. The new stylus also features pressure sensitivity technology, which means that the harder you press down on the screen, the darker or thicker the line gets. When we wrote and drew pictures with the pen, it felt effortless, like using an ink-based pen on a normal sheet of paper. In fact, it almost seems like there is no delay at all. The Surface Pro 3 has a great reaction time. The next step Microsoft took to make the Surface Pro Pen the beautiful stylus it is today, was to limit the latency, or delay time, between the moment when you finish drawing a line and the moment it appears on the screen. That’s pretty impressive. One of the things that helped Microsoft reduce the effect of parallax to that extent was its efforts to make a very thin display stack. After lots of practice and revision, the Surface Pen team managed to get the pen within 0.5 millimeters of perfection 98 percent of the time. Doing so helped them track the accuracy of the cursor as it traveled across the display. They enlisted the help of a robot to mark the Surface Pro 3’s display at 2-millimeter intervals, in a grid pattern. Microsoft engineer Stevie Bathiche and Chris Whitman, the Surface Pen Program Manager, worked tirelessly to reduce parallax until it wasn’t even noticeable anymore.
