MultiTouch is a library for computer-vision -based multi-touch screens.
MultiTouch uses a series of near-infrared (NIR) cameras to track user interaction (fingers, hands etc) on a touch-screen.
About the coordinate systems: The configuration files indicate what are the "real" coordinates used by the display device and all functions return coordinates in those coordinates. It is quite common to output coordinates that match the application window coordinates exactly (i.e. coordinates are relative to te window top-left corner). Usually the origin of the coordinate system in the top-left corner (as in GUI programming), although you can change that to your liking with the configuration settings.
The MultiTouch library has been designed to be source- and binary-compatible across different SDK releases, to the extent possible.
| QString MultiTouch::cornerstoneRoot | ( | ) |
Get the path to the root folder of the Cornerstone runtime.
| bool MultiTouch::doHardwareCheck | ( | ) |
Checks if MultiTouch hardware can be found.
| bool MultiTouch::isSDK | ( | ) |
Check if the Cornerstone SDK is installed.
| void MultiTouch::setCornerstoneRoot | ( | const QString & | root | ) |
Manually set the root folder for Cornerstone.
This can be used to overrule the default path and select where to load data etc.
| root | Cornerstone root path |
