From Dave: 
Hi guys, nice job on your sketches and it's clear you have spent some time thinking about how to add interaction to your system. Thanks for taking our comments into consideration. 

From Kimiko: 
Nice sketches and great idea to add tokens! (And I need this system installed in my door!) We would still like you to discuss your answers to the following questions we asked you before: There are several items which we need to have with us everyday. But there are also several items which are more exceptional. How does one program a system to make sure that you have that one particular item on a rare occasion, and how do you do the mapping? Have you considered how a user would configure the system? We would also encourage you to do prior arts research (both products and academic research) to make sure there is not an existing system that does similar service. For your presentation, be prepared to present and discuss a user journey that unfolds and possibly evolves over time. Good luck!
