I have never used MAX or pure data before and have been directed here by someone else. I am wanted to create an interactive art installation. I would like to connect a motion detector or simply a webcam to my computer in order to read when someone has entered the room which then triggers my installation (which is placed directly on the wall) to light up as they walk around it. Can anyone help me with this OR has anyone else done this before? thanks, i would really appreciate the help.
