Smart tupperware: Active containers for kitchen automation

Smart Tupperware is an example of a personal task assistant (PTA) for kitchen automation. The system is intended to automatically maintain inventory status of kitchen foodstuffs for the purpose of updating the userpsilas shopping list. A variety of system configurations were investigated ranging from an active system with microcontroller-based kitchen containers instrumented with sensors to passive systems with only identification tagging on the containers. A base station provides network connectivity if the application warrants.
