A Scenario

Introduction to HACS What is HACS? –Acronym for Home Appliance Control System –Integrates wireless devices and home appliances Purpose of HACS –Enables users to remotely control home appliances using their wireless devices SAVES TIME & RESOURCES!!!

Overview of HACS HACS Cell Phone PDA Oven TV Alarm

Overview of HACS (contd.) It is a system controlled by remote devices like: –Cell phones –PDAs –Palm tops –Laptops etc. In turn it controls, monitors and co-ordinates home appliances like: –Air conditioner –Alarm –Oven –TV etc.

Why HACS will work 1.Two places at once 2.Saves time 3.Save money (Long run) 4.Self Maintenance 5.Laziness

Assumptions User can operate computer, WAP enabled mobile phone, or a PDA. Servers are always on. Communication Link. Appliance are assumed to be on and in working condition.

Interaction Diagrams Model the dynamic aspects of a system. Show the interaction of any kind of instance in any view of a system’s Architecture (classes, interfaces, components, and nodes). Model the system as a whole. Are attached to use cases to model a scenario  Sequence diagram Emphasizes time ordering of messages. Depicts the lifeline of objects.  Collaboration diagram Emphasizes structural organization. Potentially easier to model complex interactions
