Are you doing a demo of working code or are you describing unwritten code? If it is the latter then you can be expect confusion, even among techies. You can describe your idea enthusiastically and people won't understand. You can sketch you idea on paper and people won't understand. You can make a mock screenshot and people won't understand. You can do a proof-of-concept implementation and people won't understand. So, you'll just have to code your app in full. You're done when people only comment negatively about your graphic design. This is especially true if they've got less experience or aptitude in usability and graphic design.
