Comparing Microsoft Pen Protocol(MPP) 1.51 and 2.0: Understanding the Differences between the Two Versions

Microsoft Pen Protocol (MPP) is a technology used in digital pens and styluses for use with Microsoft devices. MPP enables the pen or stylus to interact with the device, allowing users to write, draw, and navigate on the screen. There are currently two versions of MPP available: MPP 1.51 and MPP 2.0. In this article, we will compare the two versions of MPP and highlight the key differences between them.

Pressure Sensitivity One of the most significant differences between MPP 1.51 and MPP 2.0 is the level of pressure sensitivity supported by each version. MPP 2.0 supports up to 4096 levels of pressure sensitivity, while MPP 1.51 only supports up to 1024 levels. This means that MPP 2.0 is more responsive to the user's touch and allows for more precise control when writing or drawing on the screen.

Latency Latency is the time it takes for the device to respond to the pen's input. MPP 2.0 has significantly reduced latency compared to MPP 1.51, with as low as 20ms latency. This makes MPP 2.0 much more responsive than MPP 1.51, which can have latency of up to 42ms.

Tilt Support MPP 2.0 includes support for tilt functionality, which allows the pen to detect the angle at which it is held. This means that users can adjust the thickness and angle of their lines by tilting the pen, providing a more natural and intuitive writing and drawing experience. MPP 1.51 does not support tilt functionality.

Conclusion In summary, MPP 2.0 is a significant improvement over MPP 1.51 in terms of pressure sensitivity, latency, and tilt support. The increased pressure sensitivity and reduced latency make MPP 2.0 more responsive and accurate, while tilt support provides more options and flexibility for users.
