in previous release of ccv (1.2 and 1.3), ccv was sending a blob point trough tuio with (0.0) coordinates (so in the upper left corner) each time a blob was detected outside the calibration grid… so if you were touching the edge of your screen but a little bit outside, or complitlyoutside if your calibration box is smaller than what the cam sees, ccv was sending a (0.0) point which was really anoying…
Now this is fixed, ccv only send a blob info if it is meant to be a real blob, so inside the calibration box…
