This week I looked into various Max 7 tutorials and patcher help files, this included looking at the CV.JIT object guide. This object guide showed various uses for the CV patcher from pattern recognition, pixel tracking and uses with blobs. Looking through tutorials on interactive Max projects, I found a patcher created by a user (YANIKI), who commented on a post asking how to trigger zones using a camera. This patcher triggers when movement is detected in a certain camera area.

I linked this to a previous patcher which uses Syphon to send code to MadMapper and project an image. This creates the basic interactive element to my project where hand movement picked up by a camera triggers a video to project. However, two issues have presented themselves through this patch:

  • Unless there is constant movement in the camera zone the video pauses and resets itself.
  • MapMapper connects to the patch and finds the video, but will not play the video.
  • Max 7 cannot find the external PS2 EyeToy and this patch works using the internal camera.

In order to resolve these problems I will look into jitter tutorials on video and other relevant help articles. I will also look into buying an external webcam compatible with Max 7.
