** Bug Fixes and Improvements
The following bugs have been fixed in Version 2.3:
Precision and accuracy improvements.
** Known issues
Shiny objects such as a shiny bracelet or watch may cause ghost pointers when using Pen with Xbox sensor on a very reflective projection surface (like a white board).
The tilting function might fail due a bug in Kinect for Windows SDK. Unplug and replug the sensor if you want to use the tilting function.
Noise might occur on the left boundary of the screen. Restart Ubi if there are ghost pointers occur.
Switching the modes too fast might caused Ubi to crash or recalibration to fail.
There is a delay after clicking mode switch before it is interactive.
Switching mode from pen will cause ghost pointers during the delay time.
