Single button HEMS printer for tangible on-demand delivery of smart home information

摘要

We propose a HEMS Printer that prints smart home-related information on small pieces of paper on demand. Triggered by entrance door motion, demand-response signals, or error signals from home appliances, it prints electricity saving information, upcoming schedules, coupons of nearby stores (to encourage "cool sharing"), maps of repair shops, and so on. Our device is essentially a portable thermal printer with one LED illuminated button. The LED blinks when some information is ready. Pressing the button prints a slip of paper similar to a receipt. The main advantages of our system is its simplicity, portability and disposability of the paper, and low mental burden.
