Hi everybody,

how it is possible to define some regions on the webcamscreen like rectangles. When the user puts his hand infront of that region (image difference) than an action should be triggered.

It would be cool if someone has already something like that done.

thank you very much.

you can use pix_movement and pix_blob to detecet the motion action. find the XY of the motion to compare with the region position to trigger.

Be aware that there is an arm just after the hand and a whole body then. If you define regions in the webcam frame you may get your arm triggering unwanted regions when moving your hand. The main problem in using movement detection is the target on which detection will focus on.
Just in case you did not foresee this point in your project.
All the best
