Using the native camera as a proximity or motion sensor

This is not currently part of Kiosk Pro nor something that we are looking to develop. We have looked into this in the past and there are several areas of difficulty:

  1. This type of functionality would not be compliant with the review guidelines Apple has in place for iTunes (which, in this case, require that the user be explicitly aware that the camera is being used).
  2. This type of solution may not work well in situations with low-lighting or where the subject did not stand out from the background. In addition, it would be difficult to set certain parameters like minimum distance.

Still stuck? How can we help? How can we help?
