Microsoft's new patent exposure: expected to launch a multi-function Surface Pen

The United States Patent and Trademark Office announced a new patent on May 23, 2019, which was originally filed by Microsoft at the end of 2017. In this patent document called "Multi-Functional Stylus", Microsoft detailed the new features of this suspected new Surface Pen: the new stylus program replaces all the operations of a traditional mouse.

According to the patent document, the top of the stylus has a unique "joystick" that is similar to the use of a touchpad on a laptop. The user can control the cursor on the touch device by moving the joystick. At the same time, the joystick can also sense the applied external force and work as a "button". Similar to the click function of the mouse, the user can also assign different functions to the buttons.

Microsoft's patent also includes a concept of changing the way wireless data is transmitted based on whether the pen tip is in contact with the touch screen. Depending on how close the pen tip is, the stylus will automatically switch the data transfer between the electrostatic channel and the wireless channel.

In addition, this patent document mentions another idea to add an optical sensor to the stylus that accurately detects and tracks movement. The data collected by the optical sensor will be transmitted via an additional wireless transmitter configuration. The patent also details how to use the stylus control circuit to control the transmission of the sensor output.
