= Use Case Brain Storm = Please add new ideas to this page! * SpecificIdeasFromEric * JamieAndEricsDiscussion * Design == Use Cases == * energy saving * turn out lights based on motion * set AC to powersave (turn up temperature in summer, down in winter) while everyone is away * use system to locate lost items * game (there has to be some game that can take advantage of this system) * cell phone based control * as Chung was describing * universal remote * away from home (fire, burglar, etc.) * notifications * phone ringing message, new mail, etc. displayed on TV and other devices * TV can control devices like TVs, speakers, lights * video camera sends video directly to TV or computer * base station based control * provides cell phone and web based control * both poll and event (aka, push v. pull) based communication * difference between time left on microwave and fire alarm == Relevant Non Functional Aspects == * security * cost * installation * communication in a big house will be more difficuilt in a large house - range of wireless, etc. * maintanence * use * ease * installation * maintanence * use * a big house would need the interfaces to be able to scale (scrolling through 100+ devices would not be fun) * form queries to "search" through available devices * devices can share metadata: * room * category (entertainment, security, etc.) * use metadata to sort through devices (can order devices in different ways - akin to the different ways songs can be sorted on your iPod) * extensibility == Available Architectures == * centralized (aka. one base station) * fault-tolerant centralized (aka. one base station, but backups available) * ''EA: I don't actually know what this means to us.'' * distributed (aka. no central base station - all devices can communicate directly with all other devices) == Devices == * TV, stereo, home entertainment system * refigerator * computer * cell phone * lights * security cameras * tub * schedule it to fill up the tub with X° water to Y height * kitchen sink * we need to come up with a use case for this - it would be great to say "everything and the kitchen sink" == Communication Possibilities == * 802.11 (wireless) * Ethernet * USB * Bluetooth * IR * electric outlets
