On the touch surface area, there is a zone where the projector reflects and causes a very difficult touch detection, on the remaining area the touch sensitivity is acceptable.
We came with an idea, put another mirror in order to attenuate the intensity of reflected light.
Some temporary changes were made in Maria "body":
1- Added a mirror (a bit bigger than the other) for the extra refletion;
2- Moved the infrared lamps to another position;
3- Removed the tracing paper cover of the IR Lamps;
4- Lifted the camera calibration base.
Thus creating a set of mirror reflections (the projector to a mirror that reflects to another mirror which in turn reflects on the touch surface) that will hopefully mitigate the zone of high light intensity caused by the projector.
But we were not really successful...
That zone, that we refered, is visible at the beginning of the video (0:01), the dark squares should be homogeneous, but it is possible to see the area (bottom below, user perspective) of greater intensity.
Next days will be to improve the changes on Maria body, in order to continue on fine calibration.
