PC Tablet Platform SDK – WISPTIS.EXE
WISPTIS.EXE is part of the Tablet PC Platform SDK. You'll probably find it in your Windows\System or System32 folder. It is described as follows: "This executable runs as a system service that provides pen-data collection for other components of the SDK. When a component needs to interact with the pen (for example, to collect ink or to detect gestures), this executable is spawned as a service to communicate directly with the input device. On a Tablet PC, Wisptis.exe interacts with the digitizer, whereas on a desktop it interacts with the mouse as well. The executable’s name is an acronym that references an outdated internal name for the team that developed it (Windows Ink Services Platform Tablet Input Subsystem)."
